BACKGROUND OF THE INVENTION
  The present inventionDrawing device, drawingMethod,andDrawingThe present invention relates to a computer-readable recording medium on which a program is recorded, and in particular, it is possible to express the overlap between figures in various ways.Drawing device, drawingMethod,andDrawingThe present invention relates to a computer-readable recording medium on which a program is recorded.
[0002]
[Prior art]
A graphic processing method called a draw system that records an image as a combination of circles, polygons, or polygon figures, compared to a graphic processing method called a paint system that records an image as a bitmap or compressed data and displays it on the screen There are various application programs using the.
[0003]
The draw-type graphic processing method is smaller than the paint-type graphic processing method, so the recorded data size is small, so it is easy to handle on a computer or a network. Since it is a figure, there is an advantage that correction is easy. In particular, the advantage of the small data size is noticeable in the case of animation data whose illustration changes with time. As an example of a technique for creating and reproducing an animation using a draw-type graphic processing method, EVA animator (registered trademark of Sharp Corporation) manufactured by Sharp Corporation is known.
[0004]
On the other hand, in the draw type graphic processing method, since the image is composed of figures, it is difficult to express in detail. For this reason, in order to express a complicated shape, it is common to express a plurality of figures in combination. This is because if a complicated shape is created by one figure, for example, one polygon, the method of expressing colors in one polygon is limited. For this reason, there is a problem that it is difficult to make a shape configured with the intended color, and if a part of the shape is changed later, the operation becomes complicated. In general, a figure has attributes of its outline shape, outline color, and fill color inside the figure surrounded by the outline. For this reason, if one shape is created by combining a plurality of figures, it is possible to easily express a more complicated shape than to express one shape with one polygon.
[0005]
When creating a composite figure that combines multiple figures like this, if you do not devise any way to draw the part where each figure overlaps, it will be drawn with the outline of the figure drawn later and the internal color. The However, from the viewpoint of an operator who creates an image, there are various demands regarding how the overlapped portion is desired to be drawn.
[0006]
For example, there is a demand that the outline of each figure in a portion where a plurality of figures overlap is not desired to be drawn. As a solution to this demand, a “composite figure creation method” disclosed in Japanese Patent Laid-Open No. 3-149678 is known. This method does not draw the outline of the overlapping part of the figure only in the case of a composite figure composed of a plurality of figures having the same outline and the same internal color.
[0007]
[Problems to be solved by the invention]
As described above, there are several application programs that create illustrations and animations using a draw-type graphic processing method, and have the following problems in drawing a portion where a plurality of figures overlap.
[0008]
First, as a first problem, there is a case where an outline of each figure is not desired to be drawn at a portion where a plurality of figures of the composite figure overlap. This point will be described with reference to the drawings.
[0009]
Here, a scene in which a shape expressing a “shirt” is created is assumed. As shown in FIG. 43 (a), the “shirt” is represented by a composite figure in which the body part and the sleeve part are created with different figures, and each is partially overlapped as shown in FIG. 43 (b). Also, the body part and the sleeve part have different internal colors.
[0010]
FIG. 44 (a) is a drawing of this “shirt” using a conventional method, and it can be seen that the outline of the body portion is drawn at the boundary with the sleeve portion. However, there is a case where it is not desired to draw a boundary line with the sleeve portion, that is, as shown in FIG. In order to obtain the result shown in FIG. 44 (b) by the conventional method, in order to eliminate the boundary line with the sleeve portion, an elongated figure having the same internal color as the body portion color and having no outline is used. It must be created and placed in a position that covers the border with the sleeve. This makes the operation cumbersome and increases the data size. Therefore, a method of obtaining the drawing result shown in FIG. 44B by a simple operation without increasing the data size is desired.
[0011]
Next, as a second problem, when the composite figure is made semi-transparent for the part where multiple figures of the composite figure overlap, the internal color and outline color of the hidden part of the figure are transparent if it is opaque. There is a case where you want to make it invisible. This point will be described with reference to the drawings.
[0012]
FIG. 45A is a drawing in which the body portion and the sleeve portion of the “shirt” illustrated in FIG. 44A are rendered translucent by a conventional method, and the body portion becomes translucent. The underside can be seen through. For this reason, in FIG. 44 (a), the sleeve part hidden by the trunk | drum part will be visible. However, in this case, since the “shirt” is expressed by combining the body part and the sleeve part, as shown in FIG. 45 (b), the whole is maintained while maintaining the shape of FIG. 44 (a). It should be expressed translucently. In order to obtain the result shown in FIG. 45 (b) by the conventional method, it is necessary to create the figure of the body part and the sleeve part so that they are in close contact with each other and do not overlap. , Very troublesome. Therefore, a method for obtaining the drawing result shown in FIG. 45B by a simple operation is desired.
[0013]
Next, as a third problem, when the composite figure drawn as shown in FIG. 44B is to be translucent, if it is opaque, the internal color of the hidden part of the figure cannot be seen through. There are cases where you want to This point will be described with reference to the drawings.
[0014]
FIG. 46A is a drawing in which the body portion and the sleeve portion of the “shirt” illustrated in FIG. 44B are rendered translucently, and the outline of the portion where the figures overlap is not drawn. The internal color of the body part and the internal color of the sleeve part are mixed. In this case as well, as in the second problem, the “shirt” is expressed by combining the body portion and the sleeve portion. The whole should be translucent with its shape maintained. Therefore, a method for obtaining a drawing result as shown in FIG. 46B by a simple operation is desired.
[0015]
Next, as a fourth problem, there is a case where all the contour lines of each figure are desired to be drawn at a portion where a plurality of figures of the composite figure overlap. This point will be described with reference to the drawings.
[0016]
Here, a scene in which a shape expressing “stained glass” is created is assumed. The “stained glass” is created by three different figures as shown in FIG. 47 (a), and each is expressed by a composite figure partially overlapped as shown in FIG. 47 (b). Each figure has a different internal color.
[0017]
FIG. 48 (a) is a drawing of this “stained glass” using a conventional method. The outline of the left rhombus figure (hereinafter referred to as “left figure” as appropriate) is the right rhombus figure (hereinafter referred to as appropriate). There is a part that is not drawn because it is overwritten by the internal color of "right figure". However, there is a case where it is desired to draw all the contour lines of the left figure, that is, as shown in FIG. In order to obtain the display result as shown in FIG. 48 (b) by the conventional method, the same color as the outline of the right figure is placed at the position of the outline of the left figure overwritten by the internal color of the right figure. Line figures must be overwritten. This makes the operation cumbersome and increases the data size. Therefore, a method of obtaining the drawing result shown in FIG. 48B by a simple operation without increasing the data size is desired.
[0018]
Next, as a fifth problem, when a composite figure drawn as shown in FIG. 48 (b) is to be translucently expressed, if it is opaque, the internal color of the figure hidden, that is, the right side There is a case where it is desired to draw so that the internal color of a part of the left figure hidden behind the figure cannot be seen through. This point will be described with reference to the drawings.
[0019]
FIG. 49 (a) is a drawing of the three figures “stained glass” illustrated in FIG. 47 (b) in a semi-transparent representation, and the outlines of the portions where the figures overlap are all drawn. Of the part where the two figures overlap, that is, the part where the rhombuses overlap, the part inside the figure that is not the outline is seen through. In this case, as in the second problem, the entire “stained glass” drawn as shown in FIG. 48B should be maintained and the whole should be expressed translucently, as shown in FIG. A method for obtaining the drawing result shown in FIG.
[0020]
As described above, an object of the present invention is to provide a graphic processing method and apparatus for improving drawing of an overlapping portion of a plurality of figures, and graphic processing when an illustration or animation is created using a draw-type graphic processing method. To provide a computer-readable recording medium in which a program is recorded.

[0044]
FIG. 5 illustrates the structure of translucent pixel information. The translucent pixel information includes pixel color information 501, pixel transparency information 502, and pixel part information 503. The pixel transparency information 502 takes any value from 0 to 100. If it is 0, it is completely opaque, and if it is 100, it represents completely transparent. The pixel part information 503 takes one of three values from 0 to 2. Here, 1 represents the inside of the figure, 2 represents the outline of the figure, and 0 represents the outside of the figure.
[0045]

FIG. 7 explains the structure of the composite graphic information. In this embodiment, a plurality of composite figures can be handled. For this reason, it is necessary to identify each composite figure. Therefore, composite graphic information in which a plurality of graphic information are collected together is provided.
[0047]
The composite graphic information includes a plurality of graphic information 701 and one drawing method type information 702. The drawing method type information 702 takes a value between 1 and 5. When the drawing method type information 702 is 1, this means that if the entire composite figure is opaque, the composite figure is drawn translucently in a state in which the internal color and outline color of the hidden part are not seen through ( Corresponding to the second problem). When the drawing method type information 702 is 2, this means that the contour line of the figure is not drawn (corresponding to the first problem).

FIG. 8 is a flowchart showing a procedure until one composite graphic is recorded in the image information in the present embodiment. FIGS. 10 to 12 are flowcharts for explaining the important steps in the flowchart of FIG. FIGS. 13 to 42 illustrate the results of processing according to the steps of the flowcharts of FIGS. 8 and 10 to 12 as images. Hereinafter, the process until one composite graphic is recorded in the image information will be described with reference to the flowchart of FIG. It is assumed that a picture as shown in FIG. 9 has already been recorded in the image information before starting this processing. Further, it is assumed that the processing is started after 100, that is, completely transparent is recorded in the pixel transparency information 502 among all the translucent pixel information included in the translucent image information of FIG. This is due to the following reasons. As the final step of each execution example, the information of each pixel is synthesized and transferred from the translucent image information to the image information. At that time, when 100 is recorded in the pixel transparency information 502 of the semitransparent pixel information in the semitransparent image information, there is no figure to be synthesized or there is a figure to be synthesized. Because it is completely transparent, it is possible to judge that it is not necessary to synthesize. Therefore, it is possible to omit the step of synthesizing and transferring the pixel information itself.
[0049]
With reference to FIG. 8, a flow of a series of processes will be described. Data relating to the composite graphic to be drawn is acquired from the composite graphic information of FIG. 7 stored in the memory 110 (S802).
[0050]
It is determined whether or not all the figures have been drawn (S803). This condition judgment is to control the loop formed from S804 to S806 for creating the image of all graphic information 701 included in the composite graphic information on the translucent image information of FIG. 4 (S803). .
[0051]
If it is determined that there is an undrawn graphic (N in S803), one graphic information 701 included in the composite graphic information is acquired (S804). Next, the outline of the figure is recorded in the translucent image information of FIG. 4 (S805). Next, the inside of the figure is recorded in the translucent image information of FIG. 4 (S806), and the process returns to S803.
[0052]
When the drawing for all the figures is completed (Y in S803), the translucent image information in which the outlines and the insides of all the figures are stored is transferred to the image information in FIG. 2 (S807), and the composite figure The drawing process is terminated.
[0053]
With reference to FIG. 10, the process of S805 of FIG. 8 will be described.
A value is acquired from the drawing method type information 702 of the composite graphic information. It is determined whether the value of the drawing method type is 2 or 3 (S903). When the value of the drawing method type is 2 or 3 (Y in S903), the pixel part information 503 of the semitransparent pixel information of the portion where the outline of the semitransparent image information is to be drawn is acquired (S905). It is determined whether or not the pixel part information 503 of the translucent pixel information of the acquired translucent image information represents the inside of the figure (S906). If the pixel part information represents the inside of the figure (Y in S906), the process ends without doing anything. If the pixel part information represents something other than the inside of the figure (N in S906), the outline color of the figure and the transparency of the figure are recorded in the semi-transparent image information (S907, S908).
[0054]
If the value of the drawing method type is other than 2 and 3 (N in S903), it is determined whether the value of the drawing method type is 4 or 5 (S904). When the value of the method drawing type is 4 or 5 (Y in S904), the color of the outline of the figure is acquired from the outline color information 602 of the figure, and the translucent pixel of the translucent image information in FIG. Information is recorded in the pixel color information 501 (S909). Which semi-transparent pixel information of the semi-transparent image information is recorded is determined by whether or not the semi-transparent pixel information is at a position corresponding to the contour line of the graphic determined by the graphic outline information. That is, the value acquired from the contour color information 602 is recorded in all the translucent pixel information at the position corresponding to the contour portion of the figure.
[0055]
The transparency of the figure is acquired from the transparency information 604 of the figure and is recorded in the pixel transparency information 502 of the semitransparent pixel information of the semitransparent image information in FIG. 4 (S910).
[0056]
2 is recorded in the pixel part information 503 of the semi-transparent pixel information of the semi-transparent image information, that is, a value indicating that the figure is a contour line (S911). The translucent pixel information to be recorded is all the translucent pixel information at the position corresponding to the outline of the figure.
[0057]
When the value of the drawing method type is 1 (N in S904), the processing of S912 and S913 is executed. The processing of S912 and S913 is the same as the processing of S909 and S910, respectively. Therefore, detailed description thereof will not be repeated here.
[0058]
With reference to FIG. 11, the process of S806 of FIG. 8 will be described.
A value is acquired from the figure drawing method type 702 (S1002). It is determined whether the drawing method type is 4 or 5 (S1003). When the value of the method drawing type is 4 or 5 (Y in S1003), the pixel part information 503 of the semi-transparent pixel information of the part to be drawn inside the figure of the semi-transparent image information is acquired (S1005). If the value of the pixel part information 503 is 2, that is, the portion representing the contour of the graphic (Y in S1006), S1007 and S1008 are not executed.
[0059]
In a portion where the value of the pixel part information 503 is not 2 (N in S1006), the color and transparency inside the figure are recorded in the translucent image information (S1007 and S1008).
[0060]
If the drawing method type is other than 4 or 5 (N in S1003), it is determined whether the drawing method type is 2 or 3 (S1004). If the value of the drawing method type is 2 or 3, (S1004). Y), the internal color information and the transparency information of the figure are recorded in the translucent image information (S1009 and S1010). 1 is recorded in the pixel part information 503 of the translucent pixel information of the translucent image information, that is, a value indicating the inside of the figure (S1011).
[0061]
If the value of the drawing method type is not 2 or 3 (N in S1004), the internal color of the graphic is acquired from the internal color information 603 of the graphic and recorded in the translucent image information of FIG. 4 (S1012). . Further, the transparency of the figure is acquired from the transparency information 604 of the figure and is recorded in the pixel transparency information 502 of the semitransparent pixel information of the semitransparent image information in FIG. 4 (S1013).
[0062]
With reference to FIG. 12, the process of S807 of FIG. 8 will be described.
It is determined whether all the translucent pixel information in the translucent image information has been transferred to the corresponding pixel information of the image information (S1102). If the transfer has been completed (Y in S1102), the process is terminated.
[0063]
If the transfer has not been completed (N in S1102), the pixel transparency information 502 and the pixel color information 501 are acquired from the translucent pixel information 401 in the translucent image information (S1103, S1104). It is determined whether or not the value of the acquired pixel transparency information 502 is 0 (S1105). If the value of the pixel transparency information 502 is not 0 (N in S1105), the pixel color information 301 of the pixel information in the image information to be recorded is acquired (S1106). A color obtained by mixing the color acquired in S1106 and the color acquired in S1104 is created (S1107). After the processing of S1107 or when the value of the transparency information 502 is 0 (Y in S1105), the color generated in S1107 or the color acquired in S1104 is recorded in the pixel information of the image information (S1108). Thereafter, the process returns to S1102.
[0064]
[First execution example]
First, as a first execution example, 1 is recorded in the drawing method type information 702 in the composite graphic information of FIG. 7, and there are two graphic information included in the composite graphic information. It is assumed that the transparency information 604 records 0, that is, a value indicating complete opacity. Further, when two pieces of graphic information included in the composite graphic information are combined, it is assumed that contour information having a shape as shown in FIG. 13 is stored in the graphic information.
[0065]
First, data relating to a composite graphic to be drawn is acquired from the composite graphic information stored in the memory 110 (S802). The loop shown in S803 to S806 is a loop for creating images of all graphic information 701 included in the composite graphic information as the translucent image information of FIG.
[0066]
It is determined whether or not all figures have been drawn (S803). If there is an undrawn figure (N in S803), one figure information 701 included in the composite figure information is acquired (S804), and the outline of the figure is recorded in the translucent image information in FIG. 4 (S805). . FIG. 10 describes the process of S805 in detail. Based on FIG. 10, the process of S805 will be described in detail. First, a value is acquired from the figure drawing method type 702 (S902). The obtained result is 1, and the process proceeds to S912 as a result of the process for branching the process depending on the drawing method type (S903, S904). In S912, the color of the contour line of the graphic is acquired from the contour color information 602 of the graphic and is recorded in the pixel color information 501 of the translucent pixel information of the translucent image information in FIG. The translucent image information is obtained by arranging the translucent pixel information along the arrangement of the image, and the pixel of the translucent pixel information at a position corresponding to the contour portion of the figure determined by the outline information of the figure The color of the outline of the figure is recorded in the color information. That is, the value acquired from the contour color information 602 is recorded in all the translucent pixel information at the position corresponding to the contour portion of the figure. Similarly, in S913, the transparency of the figure is acquired from the transparency information 604 of the figure and recorded in the pixel transparency information 502 of the semitransparent pixel information of the semitransparent image information in FIG. The symbols recorded in the translucent image information at this time are as shown in FIG.
[0067]
Referring to FIG. 8 again, the inside of the graphic is also recorded in the translucent graphic information of FIG. 4 (S806). FIG. 11 illustrates the details of S806, and the processing of S806 will be described in detail with reference to FIG.
[0068]
A value is acquired from the figure drawing method type 702 (S1002). The acquired result is 1, and the process proceeds to S1012 as a result of the process of branching the process depending on the drawing method type (S1003, S1004). In S1012, the internal color of the graphic is acquired from the internal color information 603 of the graphic and recorded in the translucent image information of FIG. The translucent image information is obtained by arranging the translucent pixel information along the arrangement of the image, and the translucent pixel information of the position corresponding to the inside of the outline of the figure determined by the outline information of the figure. The color inside the outline of the figure is recorded in the pixel color information. That is, a value acquired from the internal color information 603 is recorded in all the translucent pixel information at a position corresponding to a part inside the figure. Similarly, in S1013, the transparency of the figure is acquired from the transparency information 604 of the figure and recorded in the pixel transparency information 502 of the semitransparent pixel information of the semitransparent image information in FIG. The symbols recorded in the translucent image information at this time are as shown in FIG.
[0069]
Returning to S803 of FIG. 8, there are two figures included in the composite figure. For this reason, the loop formed in S804 to S806 is executed again. The symbols recorded in the semi-transparent image information when the loop is executed twice are as shown in FIG. In this way, after the outlines and the insides of all the figures in the composite figure are recorded in the semi-transparent image information, the semi-transparent image information is transferred to the image information in FIG. 2 (S807), and the process ends.
[0070]
FIG. 12 illustrates the details of the inside of S807, and the processing of S807 will be described in detail based on FIG. S1102 is a process for controlling the loop composed of S1103 to S1108 for combining and transferring all the translucent pixel information in the translucent image information to the corresponding pixel information of the image information.
[0071]
In the loop, pixel transparency information 502 and pixel color information 501 are acquired from the translucent pixel information 401 in the translucent image information of FIG. 4 (S1103, S1104). The value of the acquired pixel transparency information is 0, indicating that the pixel is completely opaque. For this reason, it is not necessary to mix with the color of the pixel of the image information, and it is determined not to perform the color composition step (Y in S1105). That is, when the value of the pixel transparency information is 0 (Y in S1105), the pixel color information of the translucent pixel information in the translucent image information is simply overwritten on the corresponding pixel information of the image information. Become.
[0072]
If it is determined that the loop has been executed for all the translucent image pixels (Y in S1102), the translucent image composition / transfer process ends, and the composite graphic drawing process of FIG. 8 also ends. The symbols recorded in the image information at this time are as shown in FIG.
[0073]
In the above description, the drawing method type of the composite graphic information is 1. That is, in the overlapping part of the composite figure, a setting for drawing neither the outline nor the inside when the figure is completely opaque is recorded. The transparency information of each graphic included in the composite graphic information is 0, that is, it is completely opaque. For this reason, the same result as that obtained when the figures are simply overlaid is obtained. The effect of the present invention does not appear in the pattern obtained in FIG. 17, that is, the drawing result as shown in FIG. 17 is always obtained if the present invention is not carried out.
[0074]
[Second execution example]
As a second execution example, the composite graphic information drawing method type information 702 in FIG. 7 is 1, that is, if the entire composite graphic is opaque, the internal color or outline color of the hidden part of the graphic cannot be seen through. The case where the composite graphic is set to be rendered semitransparent and the transparency information 604 of each graphic included in the composite graphic information is 50, that is, recorded as translucent is described. The outline information of the figure is the same as in the first execution example. Here, the processing other than S805, S806, and S807 is exactly the same as the description of the first execution example, and therefore the description thereof will not be repeated here.
[0075]
Hereinafter, the processing of S805, S806, and S807 will be described.
First, the process of drawing the first of the two figures, that is, the first process of the loop constituted by S804 to S806 will be described. The process of generating the contour line of the graphic is the same as the process of generating the contour line of the graphic at the first loop described in the first execution example. However, the difference is that the value 50 is recorded in the transparency information of the translucent pixel information at the position corresponding to the contour line of the figure in the translucent image information. The symbols recorded in the translucent image information at this time are as shown in FIG.
[0076]
Next, the process for generating the inside of the figure is the same as the process for generating the outline of the figure in the first loop described in the first execution example. However, the difference is that the value 50 is recorded in the transparency information of the translucent pixel information at a position corresponding to the inside of the figure in the translucent image information. The symbols recorded in the translucent image information at the time when the contour line and the inside of the figure are generated in the first loop are as shown in FIG.
[0077]
Next, the second process of the loop constituted by S804 to S806 when drawing the second figure of the two figures will be described. The process of generating the contour line of the graphic is the same as the process of generating the contour line in the first loop. The symbols recorded in the translucent image information at this time are as shown in FIG. The process for creating the inside of the figure is the same as the process for creating the inside of the figure at the first loop. The symbols recorded in the translucent image information at this time are as shown in FIG. That is, in the contour generation of the graphic and the internal generation of the graphic performed at the second time of the loop, the contour line and the inside of the first graphic generated at the first time of the loop are used as the contour line of the second graphic. And the inside will be overwritten on the overlapping part.
[0078]
Since the two figures included in the composite figure information are drawn as described above, the translucent image information is transferred to the image information shown in FIG.
[0079]
With reference to FIG. 12, the process of S807 in the second execution example will be described in detail. The processing in S1102 is the same as that described in the first execution example. Therefore, detailed description thereof will not be repeated here. In S1103, pixel transparency information 502 is acquired. As a value to be acquired, 50 is acquired in the part corresponding to the inside of the figure and the outline. In step S1104, pixel color information 501 is acquired. The value of the acquired pixel transparency information is not 0, indicating that the pixel is translucent. Therefore, it is determined to proceed to the process (S1106) of mixing the colors of the pixels of the image information (N in S1105). That is, in S1106, the pixel color information 301 of the pixel information in the image information to be recorded is acquired. The acquired value is the value of the pixel color information of each pixel information constituting the pattern as shown in FIG.
[0080]
Next, a color obtained by mixing the color acquired in S1106 and the color acquired in S1104 is created (S1107). However, in the color mixing, the value of the pixel transparency information of the semitransparent pixel information of the semitransparent image information acquired in S1103, 50 in this example, is added. That is, a color is generated when the color acquired in S1104 overlaps with the color acquired in S1106 with a transparency of 50%. For this color generation method, an existing technique may be used.
[0081]
As an example of the existing technology, there is a method for determining a color used when drawing a figure having transparency, which is adopted in EVA Animation Ichiban Ver1.5 developed by Sharp Corporation. In this method, the R value of the color of the translucent image information acquired in S1104 is Rt, the G value is Gt, the B value is Bt, and the transparency information of the translucent image information acquired in S1103 is Tf (value range is 0 to 100). The R value of the color of the image information acquired in S1106 is Ro, the G value is Go, the B value is Bo, the R value of the color to be generated and overwritten on the image information is Rf, the G value is Gf, and the B value is Bf. Then, the color to be generated is determined by the following equation.
[0082]
Rf = Rt × (100−Tf) / 100 + Ro × Tf / 100
Gf = Gt × (100−Tf) / 100 + Go × Tf / 100
Bf = Bt × (100−Tf) / 100 + Bo × Tf / 100
In step S1108, the color generated in step S1107 is recorded in the pixel information 301 of the image information. As a result of combining the translucent pixel information of all the translucent image information with the pixel information of the corresponding image information, the pattern recorded in the image information is as shown in FIG. In FIG. 22, if the entire composite figure of the composite figure shown in FIG. 13 is opaque, the composite figure is expressed translucently in a state where the internal color and outline color of the hidden part are not visible. I understand that.
[0083]
[Third execution example]
Next, as a third execution example, the drawing method type information 702 of the composite graphic information in FIG. 7 is set to 2, that is, the overlapping portion of the composite graphic is set not to be drawn on the contour line or the inside. The case where the transparency information 604 of each graphic included in the graphic information is recorded as 0, that is, completely opaque will be described. The outline information of the figure is the same as in the above execution example. Here, processes other than S805, S806, and S807 are exactly the same as described above. Therefore, detailed description thereof will not be repeated here.
[0084]
Hereinafter, the processing of S805, S806, and S807 will be described.
First, the process of drawing the first of the two figures, that is, the first process of the loop constituted by S804 to S806 will be described.
[0085]
With reference to FIG. 10, processing for generating a contour of a graphic will be described. First, a value is acquired from the figure drawing method type 702 (S902). The acquired result is 2. As a result of the process for branching the process depending on the drawing method type (S903), the process proceeds to S905. In step S905, the pixel part information 503 of the translucent pixel information of the portion where the outline of the translucent image information is to be drawn is acquired. Since no graphic has been generated in the translucent image information yet, the acquired value is 0, that is, outside the graphic. A judgment that is not inside the figure is made in S906, and the color and transparency of the contour line are recorded in the translucent image information in S907 and S908. The processing in S907 and S908 is the same as the processing in S912 and S913 described above. Therefore, the description thereof will not be repeated here. The symbols recorded in the translucent image information at this time are as shown in FIG.
[0086]
With reference to FIG. 11, processing for generating the inside of a graphic will be described. First, a value is acquired from the figure drawing method type 702 (S1102). The acquired result is 2, and the process proceeds to S1009 as a result of the process (S1003, S1004) that branches the process depending on the drawing method type. In S1009 and S1010, the internal color information and the transparency information of the graphic are recorded in the translucent image information, respectively. This process is the same as S1012 and S1013 described in the first execution example. Next, in S1011, 1 is recorded in the pixel part information 503 of the semitransparent pixel information of the semitransparent image information, that is, a value indicating the inside of the figure. The translucent pixel information to be recorded is all translucent pixel information at a position corresponding to the inside of the outline of the figure. The symbols recorded in the translucent image information at this time are as shown in FIG.
[0087]
Next, the second process of the loop constituted by S804 to S806 when drawing the second figure of the two figures will be described.
[0088]
With reference to FIG. 10, processing for generating a contour of a graphic will be described. Processes other than S906, S907, and S908 are the same as the first loop process. Therefore, the description thereof will not be repeated here. Here, in the creation of the inside of the graphic of the first loop, the translucent pixel information recorded as being inside the graphic exists in the translucent image information. For this reason, S907 and S908 are not executed for the portion of the pixel for which the outline is to be drawn that is determined to be recorded in the semi-transparent pixel information as being inside the figure (Y in S906). . In a portion where the inside of the figure is not recorded in the semi-transparent pixel information (N in S906), the outline color information and the transparency information of the figure are included in the semi-transparent pixel information as in the first loop. It is recorded (S907, S908). The symbols recorded in the translucent image information at this time are as shown in FIG.
[0089]
Next, the inside of the figure is created. This process is the same as the first process, and the internal color information and transparency information of the figure are recorded in all the translucent pixel information at positions corresponding to the inside of the figure. The symbols recorded in the translucent image information at this time are as shown in FIG.
[0090]
Since the two figures included in the composite figure information are drawn as described above, the translucent image information is transferred to the image information shown in FIG. In the processing of S807, since the transparency of the graphics included in the composite graphics is all 0, it is the same as the processing of S807 shown in the first execution example. The symbols recorded in the image information at this time are as shown in FIG.
[0091]
In FIG. 27, it can be seen that the outline of the overlapping portion of the two figures (FIG. 13) constituting the composite figure is not drawn.
[0092]
[Fourth execution example]
Next, as a fourth execution example, 3 is drawn in the drawing method type information 702 of the composite graphic information in FIG. 7, that is, the entire composite graphic is drawn translucently without drawing the outline of the graphic and mixing the internal colors. A case will be described in which it is set and the transparency information 604 of each graphic included in the composite graphic information is recorded as 50, that is, translucent. The outline information of the figure is the same as in the first execution example. Here, the steps other than S805, S806, and S807 are exactly the same as the description of the first execution example. Therefore, detailed description thereof will not be repeated here.
[0093]
Hereinafter, the processing of S805, S806, and S807 will be described.
First, the process of drawing the first of the two figures, that is, the first process of the loop constituted by S804 to S806 will be described. The processing for generating the contour line of the graphic is the same as the processing for generating the contour line of the graphic at the first loop described in the third execution example. However, the difference is that the value 50 is recorded in the transparency information of the translucent pixel information at the position corresponding to the contour line of the figure in the translucent image information. At this time, the symbols recorded in the translucent image information are as shown in FIG. Next, the processing for generating the inside of the graphic is the same as the processing for generating the inside of the graphic in the first loop described in the third execution example. However, the difference is that the value 50 is recorded in the transparency information of the translucent pixel information at a position corresponding to the inside of the figure in the translucent image information. The symbols recorded in the translucent image information at the time when the contour line and the inside of the figure are generated in the first loop are as shown in FIG.
[0094]
Next, the second process of the loop constituted by S804 to S806 when drawing the second figure of the two figures will be described. The process of generating the contour line of the graphic is the same as the process of generating the contour line of the graphic in the second loop described in the third execution example. However, the difference is that the value 50 is recorded in the transparency information of the translucent pixel information at the position corresponding to the contour line of the figure in the translucent image information. The symbols recorded in the translucent image information at this time are as shown in FIG.
[0095]
Next, the process for generating the inside of the figure is the same as the process for generating the inside of the figure in the second loop described in the third execution example. However, the difference is that the value 50 is recorded in the transparency information of the translucent pixel information at a position corresponding to the inside of the figure in the translucent image information. The symbols recorded in the translucent image information at the time when the contour line and the inside of the figure are generated in the second loop are as shown in FIG.
[0096]
Since the two figures included in the composite figure information are drawn as described above, the translucent image information is transferred to the image information shown in FIG. The processing in S807 is the same as the processing for synthesizing and transferring the semi-transparent image in the second execution example because the composite graphic contains a graphic whose transparency is not 0. The symbols recorded in the image information at this time are as shown in FIG. In FIG. 32, the outline of the overlapping part of each figure included in the composite figure shown in FIG. 13 is not drawn, and the figure shown in FIG. It can be seen that it is drawn with the expression.
[0097]
[Fifth execution example]
Next, as a fifth execution example, the drawing method type information 702 of the composite graphic information shown in FIG. 7 is set to draw 4, that is, all the contour lines of the graphic, and each graphic included in the composite graphic information The case where the transparency information 604 is 0, that is, it is recorded that it is completely opaque will be described. The outline information of the figure is the same as in the first execution example. Here, the steps other than S805, S806, and S807 are exactly the same as the description of the first execution example. Therefore, detailed description thereof will not be repeated here.
[0098]
Hereinafter, the processing of S805, S806, and S807 will be described.
First, the process of drawing the first of the two figures, that is, the first process of the loop constituted by S804 to S806 will be described.
[0099]
With reference to FIG. 10, processing for generating a contour of a graphic will be described. First, a value is acquired from the figure drawing method type 702 (S902). The acquired result is 4, and the process proceeds to S909 as a result of the process of branching the process depending on the drawing method type (S903, S904). The processing of S909 and S910 is the same as the processing of S912 and S913 described in the first execution example.
[0100]
Next, in S911, 2 is recorded in the pixel part information 503 of the semi-transparent pixel information of the semi-transparent image information, that is, a value indicating the contour line of the figure. The translucent pixel information to be recorded is all the translucent pixel information at the position corresponding to the outline of the figure. The symbols recorded in the translucent image information at this time are as shown in FIG.
[0101]
With reference to FIG. 11, processing for generating the inside of a graphic will be described. First, a value is acquired from the figure drawing method type 702 (S1002). The acquired result is 4, and the process proceeds to S1005 as a result of the process for branching the process depending on the drawing method type (S1003).
[0102]
In S1005, the pixel part information 503 of the translucent pixel information of the part to be drawn inside the figure of the translucent image information is acquired. It is determined that the next S1007 and S1008 are not performed on the portion where the value acquired in S1005 is 2, that is, the contour line of the figure (Y in S1006).
[0103]
If the value acquired in S1005 is not 2 (N in S1006), the color and transparency inside the figure are recorded in the translucent image information in S1007 and S1008. However, in the first loop, only the outline image of the first figure is recorded in the semi-transparent image information, and the outline and the inside of the first figure are always in different positions. For this reason, S1007 and S1008 are necessarily executed. The processing of S1007 and S1008 is the same as the processing of S1012 and S1013 described in the first execution example. The symbols recorded in the translucent image information at this time are as shown in FIG.
[0104]
Next, the second process of the loop constituted by S804 to S806 when drawing the second figure of the two figures will be described. The process for generating the contour line is the same as the process for generating the contour line in the first loop. That is, in the generation of the contour line in the second loop, the contour part of the first graphic generated in the first loop is overwritten with the contour part of the second graphic. become. The symbols recorded in the translucent image information at this time are as shown in FIG.
[0105]
The process of creating the inside of the figure is the same as the process of creating the inside of the loop for the first time, but here it is recorded in the translucent image information that it is the outline of the first figure. It should be noted that semitransparent pixel information exists. It is determined that S1007 and S1008 are not executed for the portion where the semi-transparent pixel information is recorded as the outline of the figure (Y in S1006). For this reason, the translucent pixel information recorded in the translucent image information as the outline of the first graphic is not overwritten and recorded with the internal color and transparency of the second graphic. The color and transparency of the outline of the eye figure are retained. The symbols recorded in the translucent image information at this time are as shown in FIG.
[0106]
Since the two figures included in the composite figure information have been drawn (Y in S803 in FIG. 8), the translucent image information is transferred to the image information in FIG. The process of S807 is the same as the process of combining and transferring the translucent image described in the first execution example. The symbols recorded in the image information at this time are as shown in FIG. In FIG. 37, it can be seen that the outlines of the two figures (FIG. 13) constituting the composite figure are all drawn.
[0107]
[Sixth execution example]
Next, as a sixth execution example, 5 is drawn in the drawing method type information 702 of the composite graphic information shown in FIG. 7, that is, the entire contour of the graphic is drawn semitransparently without mixing the outline of the graphic. A case will be described in which the transparency information 604 of each graphic included in the composite graphic information is recorded as 50, that is, translucent. The outline information of the figure is the same as in the first execution example. Here, the steps other than S805, S806, and S807 are exactly the same as the description of the first execution example. Therefore, detailed description thereof will not be repeated here.
[0108]
Hereinafter, the processing of S805, S806, and S807 will be described.
First, the process of drawing the first of the two figures, that is, the first process of the loop constituted by S804 to S806 will be described. The process of generating the contour line of the graphic is the same as the process of generating the contour line of the graphic in the first loop described in the fifth execution example. However, the difference is that the value 50 is recorded in the transparency information of the translucent pixel information at the position corresponding to the contour line of the figure in the translucent image information. At this time, the symbols recorded in the translucent image information are as shown in FIG.
[0109]
Next, the processing for generating the inside of the graphic is the same as the processing for generating the inside of the graphic in the first loop described in the fifth execution example. However, the difference is that the value 50 is recorded in the transparency information of the translucent pixel information at a position corresponding to the inside of the figure in the translucent image information. FIG. 39 shows the symbols recorded in the translucent image information at the time when the contour line and the inside of the figure are generated in the first loop.
[0110]
Next, the second process of the loop constituted by S804 to S806 when drawing the second figure of the two figures will be described. The processing for generating the contour line of the graphic is the same as the processing for generating the contour line of the graphic in the second loop described in the fifth execution example. However, the difference is that the value 50 is recorded in the transparency information of the translucent pixel information at the position corresponding to the contour line of the figure in the translucent image information. The symbols recorded in the translucent image information at this time are as shown in FIG. Next, the process for generating the inside of the graphic is the same as the process for generating the inside of the graphic in the second loop described in the fifth execution example. However, the difference is that the value 50 is recorded in the transparency information of the translucent pixel information at a position corresponding to the inside of the figure in the translucent image information. The symbols recorded in the translucent image information at the time when the contour line and the inside of the figure are generated in the second loop are as shown in FIG.
[0111]
Since the two figures included in the composite figure information are drawn as described above, the translucent image information is transferred to the image information shown in FIG. In the processing of S807, since the translucency is not 0 in the translucent pixel information of the translucent image information, that is, there is a pixel indicating that it is translucent, the translucent image described in the third execution example is synthesized. It is the same as the process to transfer. The symbols recorded in the image information at this time are as shown in FIG. In FIG. 42, it can be seen that the outlines of the two figures (FIG. 13) constituting the composite figure are all drawn and that the entire composite figure is drawn translucently.
[0112]
As described above, according to the present embodiment, when an illustration or animation is created using a draw-type graphic processing method, it is possible to improve the conventional problems related to the drawing of overlapping portions of a plurality of figures. It becomes like this.
[0113]
The embodiment disclosed this time should be considered as illustrative in all points and not restrictive. The scope of the present invention is defined by the terms of the claims, rather than the description above, and is intended to include any modifications within the scope and meaning equivalent to the terms of the claims.
[0114]
【The invention's effect】
According to the present invention, it is possible to perform an expression such that the outline of each figure is not drawn or all of the overlapping parts of a composite figure in which a plurality of figures are overlapped is drawn. In addition, with respect to the overlapping portion of the composite figures in which a plurality of figures are overlapped, it is possible to express the composite figure in a translucent state while not expressing the outline of each figure or drawing all of them.
