  The drawing creation program storage unit 21 is configured by a storage medium such as a ROM, for example, and various types such as a drawing creation program (including a three-dimensional shape figure creation program) for causing the control unit 11 to execute various processes related to drawing creation. This is a storage medium for storing the data.

  The graphic-related data storage unit 22 is configured by a storage medium such as a ROM or a RAM, for example, and is a storage medium that stores various data such as graphic-related data described later.

Next, the operation of the drawing creation apparatus 100 of this example will be described.
FIG. 2 is a flowchart showing an example of a figure creation process (three-dimensional shape figure creation process) executed by the drawing creation apparatus 100. The graphic creation process is started, for example, in response to the user X starting the drawing creation software. Note that the contents of processing not related to the present invention may be omitted.

  First, the control unit 11 performs a process of displaying the initial screen of the graphic creation screen on the display unit 13 (step S101).

  FIG. 3 is an explanatory diagram showing an example of a graphic creation screen. In the figure creation screen, for example, as shown in FIG. 3, a display area 101 for displaying a drawing such as the figure being created, and a three-dimensional shape figure displayed in the display area 101 are edited in detail (enlargement and reduction). Edit button 102 that is pressed when the display area 101 is deformed, an enlargement button 103 that is pressed when the figure displayed in the display area 101 is enlarged, and a figure that is displayed in the display area 101 is reduced. A reduction button 104 that is pressed when the drawing is performed, an end button 105 that is pressed when the creation of the drawing including the graphic is finished, a drawing button 107 that is pressed when the two-dimensional part data is created, and the display area 101 A save button 106 that is pressed when saving a drawing including a figure displayed on the screen, adjustment buttons 201 to 203 that are selected when adjusting two-dimensional component data, and a two-dimensional portion. Data is provided and a part display area 301 to 303 to be displayed, further cursor K is displayed.

  In the initial screen, no graphic is displayed in the display area 101 and the component display areas 301 to 303. Note that the adjustment buttons 201 to 203 provided on the graphic creation screen are buttons that are selected for editing the planar shape graphic indicated by the two-dimensional component data displayed in the display area 101. . These adjustment buttons 201 to 203,... Can be arbitrarily selected for each planar shape figure indicated by each two-dimensional component data.

  Here, “two-dimensional part data” will be described. “Two-dimensional part data” means data indicating a planar shape figure constituting a part of a three-dimensional shape figure. The two-dimensional component data includes two-dimensional base part data indicating a planar shape figure serving as a base of the three-dimensional shape figure and two-dimensional superposition indicating a plane shape figure superimposed on the plane shape figure indicated by the two-dimensional base part data. It is assumed that there is part data. In this example, a three-dimensional shape figure is created from the two-dimensional base part data indicated by the two-dimensional base part data and the one or more two-dimensional superimposed part data indicated by the two-dimensional superimposed part data superimposed on the plane shape figure. Is done.

  In the initial screen, when the control unit 11 accepts pressing of the drawing button 107 by the operation of the operation unit 12 of the user X (for example, the operation of the cursor K), the control unit 11 displays a planar figure according to the operation of the operation unit 12 of the user X. For example, as shown in FIG. 3, the created planar shape figure is displayed in the display area 101 (step S102). In this example, the control unit 11 creates two-dimensional base part data indicating a planar shape figure corresponding to the operation of the operation unit 12 of the user X in step S102.

  Next, the control unit 11 copies the two-dimensional base part data created on the display area 101 in accordance with the operation of the operation unit 12 of the user X, and the planar shape figure indicated by the copied two-dimensional base part data Are displayed in part or all of the component display areas 301 to 303 (step S103). In this example, in accordance with the operation of the operation unit 12 of the user X, the planar shape figure indicated by the copied two-dimensional base part data is displayed in three parts of the part display areas 301 to 303.

  Next, the control unit 11 adjusts the planar shape figure in the region selected by the operation of the operation unit 12 of the user X among the component display regions 301 to 303 according to the operation of the operation unit 12 of the user X. Thus, a process of creating two-dimensional superimposed part data is performed (step S104). In this example, the control unit 11 displays, in the display region 101, the planar shape figure in the region selected by the operation of the operation unit 12 of the user X among the component display regions 301 to 303, and the operation unit 12 of the user X The adjustment of the content indicated by the adjustment buttons 201 to 203 pressed by the operation is executed on the display area 101 in accordance with the operation of the operation unit 12 of the user X. The adjustment contents executed on the display area 101 are reflected in the display contents of the corresponding component display area among the component display areas 301 to 303.

  Specifically, when the adjustment button 201 for performing highlight processing is pressed, the control unit 11 determines a part of the corresponding planar shape figure in accordance with the subsequent operation of the operation unit 12 of the user X. Is adjusted so that light is received from a predetermined direction. Further, when the adjustment button 202 for performing Jado processing is pressed, the control unit 11 darkens a part or the periphery of the corresponding planar shape figure in accordance with the subsequent operation of the operation unit 12 of the user X. Then, the adjustment processing is performed so as to indicate the shadow portion of the planar shape figure indicated by the corresponding two-dimensional base component data. Further, when the adjustment button 203 for performing the trimming process is pressed, the control unit 11 cuts out a part of the corresponding planar shape figure in response to the subsequent operation of the operation unit 12 of the user X. The adjustment processing is performed so as to show a part of the planar shape figure indicated by the two-dimensional base part data. The adjustment contents indicated by the adjustment buttons 201 to 203 are merely examples, and other contents may be adjusted. Further, a plurality of types of adjustments may be performed on the same planar figure.

  In this example, in step S104, the planar shape graphic displayed in the component display area 301 is subjected to highlight processing, and the planar shape graphic displayed in the component display region 303 is subjected to shadow processing. To do. Since the planar shape graphic displayed in the component display area 302 is handled as a planar shape graphic indicating the two-dimensional base component data, no processing is performed in step S104. Therefore, for example, as shown in FIG. 4, a planar shape figure subjected to highlight processing is displayed in the component display area 301 on the figure creation screen, and the planar shape figure indicated by the two-dimensional base part data in the component display area 302. Is displayed as it is, and a planar shape figure subjected to shadow processing is displayed in the component display area 303. In FIG. 4, the planar shape figure displayed in the currently selected component display area 301 is displayed in the display area 101.

  Then, the control unit 11 creates a three-dimensional shape figure using a plurality of two-dimensional part data displayed in the part display areas 301 to 303 according to the operation of the operation unit 12 of the user X, for example, FIG. As shown in FIG. 5, processing for displaying in the display area 101 is performed (step S105). That is, in step S105, the control unit 11 displays the two-dimensional part shape figures indicated by the plurality of two-dimensional part data displayed in the part display areas 301 to 303 created by the user X in a predetermined order. By superimposing, a three-dimensional figure is created. In this example, for example, the planar shape figure HAb indicated by the two-dimensional base part data displayed in the part display area 302 is placed on the planar shape figure HAc indicated by the two-dimensional superimposed part data displayed in the part display area 303. A three-dimensional shape graphic is created by superimposing and further superimposing the planar shape graphic HAa indicated by the two-dimensional superimposed component data displayed in the component display area 303 thereon. Note that the order of superimposition may be specified by the user X.

  When the edit button 102 is pressed in a state where a three-dimensional shape graphic is displayed in the display area 101, the control unit 11 can execute a graphic creation screen (not shown) that can perform editing operations (deformation, enlargement, reduction, coloring, etc.). Is displayed on the display unit 13. In this example, it is assumed that 3D graphic data indicating a 3D shape graphic is composed of vector data, and various editing operations such as deformation can be performed.

  Thereafter, when the save button 106 is pressed by the operation of the operation unit 12 of the user X, the control unit 11 stores drawing data including 3D shape graphic data indicating the 3D shape graphic displayed in the display area 101. The data is stored in a storage medium included in 100 (step S106).

  When the end button 105 is pressed by the operation of the operation unit 12 of the user X (Y in step S107), the control unit 11 ends the graphic creation process.

[Second Embodiment]
In the first embodiment described above, a plurality of two-dimensional part data is created from the beginning in accordance with the operation of the user X. However, a plurality of planar shape figures that constitute a part of a three-dimensional shape figure in advance are used. Each of the two-dimensional component data shown may be stored, and a plurality of new two-dimensional component data may be created using the plurality of two-dimensional component data. In this case, each of the two-dimensional parts indicating a plurality of planar shape figures constituting a part of the three-dimensional shape figure together with the three-dimensional shape figure data indicating the three-dimensional shape figure when saved in step S106 described above. Save the data. In addition, the administrator of the drawing creation apparatus 100 may create and save each two-dimensional part data indicating a plurality of planar shape figures constituting a part of the three-dimensional shape figure.

  FIG. 7 is an explanatory diagram showing an example of graphic-related data used in this example. The figure-related data is data associated with each three-dimensional shape figure corresponding to each of two-dimensional part data constituting a part of the three-dimensional shape figure. Specifically, in this example, as shown in FIG. 7, the graphic-related data can specify the specific shape of the three-dimensional shape graphic in the corresponding graphic category in the graphic category indicating the type of the three-dimensional shape graphic. This is data in which a graphic type is associated with a plurality of two-dimensional component data (2D component data) constituting a three-dimensional shape of the corresponding graphic type. It is assumed that the graphic related data is created in advance and registered in the graphic related data storage unit 22. It is assumed that a plurality of two-dimensional component data constituting a three-dimensional shape includes one two-dimensional base component data and one or more two-dimensional superimposed component data.

  Examples of the figure category include three-dimensional shapes such as an ellipsoid, a cigar, a polyhedron, and a cone. Further, it is assumed that a specific shape of a solid shape indicated by each graphic category to which the graphic type belongs is assigned to each graphic type. Specifically, for example, as a graphic type belonging to the graphic category “ellipsoid”, a sphere (type A), an ellipsoid when rotated about the major axis of an ellipse whose distance between the focal points is 1 cm (type B) ), An ellipsoid (type C) obtained by rotating the long axis of an ellipse having a distance between the focal points of 5 cm as an axis. Further, for example, regular tetrahedron (type A), regular octahedron (type B), and the like correspond to the graphic type belonging to the graphic category “polyhedron”.

  The two-dimensional component data is planar shape graphic data that constitutes a part of the corresponding graphic type of three-dimensional shape graphic. By using a plurality of two-dimensional part data associated with the graphic type, a corresponding three-dimensional graphic figure of the graphic type is created. The two-dimensional part data is associated with each graphic type. However, when the same two-dimensional part data can be used for a part of a three-dimensional shape graphic of a different graphic type, the same two-dimensional part data is used. May be associated with three-dimensional shape figures of different figure types.

  The two-dimensional component data includes plane shape graphic data in which pixel information has been changed and plane shape graphic data in which no pixel information has changed. There is also two-dimensional component data indicating a shadow appearing by a three-dimensional shape graphic of a corresponding graphic type.

Next, the operation of the drawing creation apparatus 100 of this example will be described.
FIG. 8 is a flowchart illustrating an example of a figure creation process (three-dimensional shape figure creation process) executed by the drawing creation apparatus 100. The graphic creation process is started, for example, in response to the user X starting the drawing creation software. Note that the contents of processing not related to the present invention may be omitted. Further, parts that perform the same processing as in the first embodiment described above are assigned the same step numbers, and detailed descriptions thereof are omitted.

  First, the control unit 11 performs processing for displaying the initial screen of the graphic creation screen on the display unit 13 (step S101), and accepts a reading graphic selection request by the operation of the operation unit 12 of the user X (step S201). Upon receiving the read figure selection request, for example, as shown in FIG. 9, the control unit 11 displays figure category buttons 401 to 403 on the figure creation screen in order to present categories of three-dimensional figure figures that can be created. In this example, a read button 108 is provided on the initial screen for requesting to select a figure to be read (see FIG. 9).

  Next, when accepting selection of a graphic category by the operation of the operation unit 12 of the user X (step S202), the control unit 11 presents a graphic type of a three-dimensional shape graphic that can be created (step S203).

  For example, when the user X operates the cursor K on the figure creation screen (see FIG. 9) and presses the figure category button 402 of the figure category “cigar shape”, the control unit 11 accepts the selection of the figure category “cigar shape”. In step S203, for example, a graphic creation screen provided with graphic type buttons 402a to 402c indicating graphic types belonging to the graphic category “cigar shape” as shown in FIG. 10 is displayed.

  Next, when the control unit 11 accepts selection of a graphic type by the operation of the operation unit 12 of the user X (step S204), the two-dimensional component constituting a part of the three-dimensional graphic of the graphic type selected by the user X Each piece of data is read from the figure-related data storage unit 22, and a figure creation screen is displayed in which the planar shape figure indicated by the read two-dimensional part data is displayed in the part display areas 301 to 303.

  For example, when the user X operates the cursor K on the figure creation screen shown in FIG. 10 and presses the figure type button 402a of the figure type A, the control unit 11 selects the figure type A in the figure category “cigar shape”. Accepts and reads each of a plurality of 2D part data constituting 3D shape figure data indicating a 3D shape figure of figure type A from the figure related data storage unit 22, and the plane shape figure indicated by the read 2D part data is a part. The graphic creation screen (for example, see FIG. 4) displayed in the display areas 301 to 303 is displayed.

  Next, the control unit 11 displays the planar shape figure indicated by the two-dimensional base part data displayed on the display area 102 selected by the operation of the operation unit 12 of the user X according to the operation of the operation unit 12 of the user X. Is adjusted according to the operation of the operation unit 12 of the user X to perform processing for creating new two-dimensional base part data (step S102). In this example, the control unit 11 adjusts the content indicated by the adjustment buttons 201 to 203 pressed by the operation of the operation unit 12 of the user X, scale adjustment, color adjustment, texture adjustment indicated by other adjustment buttons (not shown), The shape adjustment is executed on the display area 101 in accordance with the operation of the operation unit 12 of the user X. The adjustment contents executed on the display area 101 are reflected in the display contents of the component display area 302. In addition, for predetermined adjustment (for example, scale adjustment, texture adjustment, color adjustment, shape adjustment, etc.) in the planar shape figure indicated by the two-dimensional base component data, the control unit 11 is displayed in the other component display areas 301 and 303. It is desirable to perform the process of reflecting in the planar shape figure indicated by the two-dimensional superimposed component data.

  Next, the control unit 11 selects the planar shape graphic in the region selected by the operation of the operation unit 12 of the user X among the component display regions 301 and 303 in which the planar shape graphic indicated by the two-dimensional superimposed component data is displayed. A process of creating new two-dimensional superimposed component data is performed by adjusting according to the operation of the operation unit 12 of the user X (step S204). In this example, the control unit 11 adjusts the content indicated by the adjustment buttons 201 to 203 pressed by the operation of the operation unit 12 of the user X, scale adjustment, color adjustment, texture adjustment indicated by other adjustment buttons (not shown), The shape adjustment is executed on the display area 101 in accordance with the operation of the operation unit 12 of the user X. Note that in this example, the adjustment in step S202 may be automatically reflected in the two-dimensional superimposed component data, and the process in step S204 may not be executed.

  Then, the control unit 11 creates a three-dimensional shape figure using a plurality of newly created two-dimensional component data displayed in the component display areas 301 to 303 in accordance with the operation of the operation unit 12 of the user X. Then, a process of displaying in the display area 101 is performed (step S105). Then, the process of step S106-step S107 is performed and a figure creation process is complete | finished.

  In the above example, a specific example in which the graphic category “cigar shape” is selected has been described, but the same applies to the case where another graphic category is selected. For example, the user X operates the cursor K on the graphic creation screen shown in FIG. 9 and presses the graphic category button 403 of the graphic category “polyhedron”, and then displays the graphic creation screen (as shown in FIG. 10). When the graphic type button of graphic type X is pressed on the screen), the control unit 11 accepts selection of the graphic type X in the graphic category “polyhedron” and configures a three-dimensional graphic of graphic type X in the graphic category “polyhedron”. A plurality of two-dimensional component data is displayed in the component display area of the graphic creation screen. Then, after a plurality of two-dimensional part data is adjusted (steps S102 and S104), a three-dimensional shape figure is created by superimposing the respective plane shape figures indicated by the new adjusted two-dimensional part data, For example, as shown in FIG. 11, the created three-dimensional figure is displayed in the display area 101. In this example, as shown in FIG. 12, the 3D shape figure of the figure type X in the figure category “polyhedron” is created by using the 2D part shape figures TXa to TXf indicated by the 6 2D part data, respectively. Shall. Specifically, it is created by superimposing the two-dimensional part shape figure TXe on the upper side of the two-dimensional part shape figure TXfc, and further superimposing the two-dimensional part shape figures TXa to TXd on predetermined positions above the two-dimensional part shape figure TXfc.

  In the above example, the graphic related data as shown in FIG. 7 is used. However, for example, graphic related data as shown in FIG. 13 may be used. That is, the same is true for the point that the figure-related data is data associated with the corresponding three-dimensional shape figure of each of the two-dimensional part data constituting a part of the three-dimensional shape figure. The graphic category indicating the type may be data in which a plurality of two-dimensional component data (2D component data) constituting a three-dimensional shape in the corresponding graphic category is associated. That is, a three-dimensional figure having a predetermined shape may be associated with each figure category.
