Description

Method and device for drawing image in computer aided drawing

Technical Field

The invention relates to the technical field of computer-aided drawing, in particular to a method and a device for drawing an image in computer-aided drawing.

Background

Computer drawing technology is an indispensable application technology means for each engineering designer in the modern times, and computer drawing refers to a technology for realizing graphic display, auxiliary drawing and design by applying drawing software and computer hardware. With the development of modern science and production technology, the drawn patterns become more and more complex, and higher requirements are put on the precision and speed of drawing, so that the manual drawing is dwarfed in the drawing precision and the drawing speed. The successive advent of computers and plotters and the development of related software technology enable the application of computer plotting to meet the requirements of high precision and high speed, and enable the modern plotting technology level to reach an unprecedented level.

At present, in the industry of domestic landscape architecture, drawing software commonly used by various large, medium and small enterprises or individual garden designers is CAD, and the most common CAD is Tianzheng building CAD and Zhongcheng building CAD. The two CAD software are oriented to the design industry, and comprise mechanical design, architectural design, indoor design, advertisement design and the like. Even if all the drawing functions are universal, the requirements of garden design can be basically met on the use level. However, in the face of the day-to-day landscape industry market, the existing functions of these mapping software gradually lose competitiveness in the mapping speed and quality of the design project, and for this reason, we begin to explore to improve our competitiveness through the secondary development of software.

On the CAD software platform, although the function of filling one-key patterns for circular roads in projects is provided, the function corresponds to a linear circular road or platform, and the filling of arc roads in the projects needs to use a single manual function expected to be carried by the user, draw lines and offset one by one according to the shape, length and width of the roads, and realize centripetal paving and butt joint of offset line segments. This simple pavement filling pattern can be filled manually, but is relatively complex and time consuming for the pavement pattern shown in fig. 1.

Fig. 2 is a schematic flow chart of a method for drawing an image in computer-aided drawing according to an embodiment of the present application. As shown in fig. 2, the method may include the steps of:

s210, determining a target legend to be arrayed and a target array path, wherein the target array path has radian, and the target legend corresponds to a standard section and discrete points.

The array is mainly used for creating object copies arranged in a specified manner, and in the embodiment of the application, the specified manner includes a manner of arranging according to a target array path.

The target graph is an object to be arrayed, and the target graph can be, for example, a mat, a fill, a primitive, or a part, etc.

The standard segment may be a pattern of a target legend, such as a paving pattern. The standard section of the pavement pattern can be manufactured in advance, and the width and the length of the circular road filled by the standard section of the pavement are not limited.

The target array path may be a full arc or a partial arc. Typically the center line of a road or the edges of two sides of a road.

The discrete points may be key points for the profile criteria segment. For example, the number of discrete points may be determined according to a discrete accuracy, which may be determined according to actual needs. For example, the discrete accuracy may be higher for a standard segment having a relatively complex structure, and the discrete accuracy may be lower for a standard segment having a simple structure, which is determined according to the kind and number of graphics included in the standard segment.

Wherein the standard segment may comprise a physical line. The discrete accuracy may be determined first; the solid line is then discretized into discrete points according to a discretization precision.

And S220, determining the to-be-arrayed section corresponding to the target array path and the reference line of each to-be-arrayed section based on the standard section, wherein the reference line of the to-be-arrayed section corresponding to the array path with the radian also has the radian.

A segment to be arrayed may refer to an area for placing a copy of an object. I.e. the target array path may be divided into a plurality of segments according to the standard segments.

The reference line may be used to indicate the deformation of the to-be-arrayed segment relative to the standard segment.

S230, updating the discrete points of the target legend based on the reference lines for each reference line having a radian.

The discrete points of the target legend can be updated based on the deformation recorded by the reference line relative to the standard segment, so as to obtain deformed discrete points (i.e. updated discrete points).

And S240, filling the target legend in the segment to be arrayed based on the updated discrete points.

And deforming the target legend based on the updated discrete points to obtain deformed object copies.

The standard section of the pavement pattern can be manufactured in advance, the width and the length of a round road which is filled by the standard section of the pavement are not limited, and then the path (generally, the center line of the road or the side lines on two sides of the road), the interval (if the road needs to be beaten by waves, namely, different stones are separated, the interval needs to be input) and the fitting precision (the fitting precision of the arc road) of the array are selected; after the array path, the distance and the fitting precision are determined, if the selected path is a road center line, the lofting step can be completed by generally pressing a space key as a default, the complicated step of manually shifting line segments one by one according to the arc shape can be omitted, only a small section of paving pattern standard segment needs to be prepared in advance, the center line or the circular path side line of the arc circular path is selected, and one-key filling can be performed, so that the opposite-seam centripetal paving of the arc circular path stone is realized.

In some embodiments, the standard segment comprises an outsourcing rectangle, the outsourcing rectangle having a length and a width corresponding thereto; the step S220 may include the following steps:

step 1), according to the width of a standard segment, carrying out left-right offset on a target array path to obtain a multi-segment line;

and 2) segmenting the multiple sections of lines according to the length of the standard section to obtain sections to be arrayed, wherein the arcs with small radius in the sections to be arrayed are the datum lines of the array. The left and right offset lines after being divided can be compared one by one for judgment, and if the arc lines exist, the arc line with the small radius is judged to be the datum line of the array. Accumulating the segmented reference lines of each section, wherein the total length is the total length of the array line; the total length/length of the outer rectangle yields the number of arrays of standard segments.

Based on this, the step S230 may specifically include the following steps:

step 3), corresponding the standard section to a corresponding section to be arrayed according to the position of each section of reference line;

and 4), recalculating the X, Y value to obtain the updated discrete point by taking the tangential direction of the datum line as the X-axis direction and the vertical direction as the Y-axis direction of the discrete point of the standard section.

Based on this, the step S240 may specifically include the following steps:

and 5) connecting the updated discrete points by using lines to obtain an image after the array.

As an example, a first setup interface may be provided in which standard segments may be set and the precision of the dispersion may be set. For example, as shown in fig. 3, the first setting interface may include a standard segment selection control, and clicking the reselection control may jump to the standard segment selection interface, as shown in fig. 4, the standard segment selection interface may be an image drawing interface, a drawn image may be selected on the image drawing interface as a standard segment, or the standard segment may be drawn on the drawing interface. For another example, the first setting interface may include a standard segment selection control, and the standard segment selection control may include a standard segment selection list, and alternative standard segments may be provided in the list and may be selected from the alternative standard segments. The first setting interface can be displayed after the super lofting control or the function is triggered in the drawing process. The function of triggering the super lofting can be triggered by a shortcut key or a shortcut command.

After the standard segment is determined, the discrete accuracy may also be set. The discrete precision may be the number of discrete points or the density of discrete points, etc.

In some embodiments, the discrete precision may also be set based on the standard segment. For example, a discrete precision setting control may be provided in the first setting interface, and a jump may be made to the discrete setting interface by clicking the discrete precision setting control, as shown in fig. 5, where the reference segment is a rectangle, the discrete setting interface may be an image drawing interface, a graph of a standard segment and initial discrete points corresponding to the standard segment may be displayed in the discrete setting interface, the number of discrete points may be increased or decreased in the interface, and the positions of the discrete points may also be moved. The increase or deletion of the number of discrete points may be performed with respect to one or more selected points, or increase the vicinity or middle of one or more selected points, or increase or delete the number of discrete points as a whole, for example, a numerical value of the number of discrete points may be input, and the corresponding number of discrete points may be automatically arranged on the standard segment based on the numerical value, for example, the discrete points may be uniformly arranged. For the movement of the position of the discrete point, the discrete point can be directly dragged, or the discrete point can be selected and the coordinate of the position of the discrete point is input. For the positions and the number of the discrete points, constraint conditions can be configured in advance, and the constraint conditions can include the maximum value and the minimum value of the number of the discrete points; the location of the discrete points must be on the graph, and so on. The position and the number of discrete points may be set based on a constraint condition.

After the standard segment is determined, an array path may also be selected. For example, an array path selection control may be provided in the first setting interface, a jump may be made to the array path selection interface by clicking the control, the array path selection interface may be a drawing interface of an image, a part of a drawn graph may be selected as an array path in the array path selection interface, or an array path may be drawn, where the array path may include a radian.

As shown in fig. 5, after the information is determined, the length and width of the standard segment outsourcing rectangle can be calculated; and (3) dispersing each entity line in the standard segment into discrete points according to the input discrete precision to obtain a discrete point set (comprising discrete points A, B, C, D, E and F) of the standard segment.

The path can be shifted left and right according to the width of the standard section according to the selected path, and the shifted left and right paths are converted into PL lines. And (3) dividing the left PL line and the right PL line according to end points, comparing the divided left deviation line and the right deviation line one by one, and if both the divided left deviation line and the divided right deviation line have arc lines, judging the arc line with a small radius as a datum line of the array. Accumulating the segmented reference lines of each section, wherein the total length is the total length of the array line; obtaining the array number of the standard sections by the total length/the length of the outer-wrapped rectangle;

as shown in fig. 6, the standard segments are mapped to corresponding positions according to the position of each segment reference line.

As shown in fig. 7, the tangent direction of the reference line of the discrete point of the standard segment is taken as the X-axis direction, and the vertical direction is taken as the Y-axis direction, and the X, Y value is recalculated to obtain a new discrete point; the effect after array is obtained by connecting the deformed discrete points with lines as shown in fig. 7.

In some embodiments, the standard section may include a standard pattern and a gap, the gap may be disposed on one side or both sides of the pattern, and the size of the gap may be determined according to a construction process and an aesthetic property of the pattern. The standard pattern may be a user-selected pattern that requires bulk fill or array replication.

As an example, as shown in fig. 8, the super lofting function solves the difficulty that the CAD software platform cannot perform one-key filling on a circular road with an arc-shaped line segment and realize centripetal paving, and the super lofting function can eliminate the tedious step of manually shifting the line segment one by one according to the arc shape, and only needs to prepare a small section of standard paving pattern segment in advance, select the center line or the circular road side line of the arc-shaped circular road, and then perform one-key filling, so as to realize the centripetal paving of the arc-shaped circular road stone material by means of the butt joint.

In some embodiments, the method may further include the following steps to facilitate the widget arrangement.
