Embodiment Construction

[0017] The technical scheme of the present invention is described in detail below in conjunction with accompanying drawing:

[0018] The idea of ​​the present invention is to divide the multi-line width triangle into 6 filled triangles, and obtain the multi-line width triangle without distortion by drawing the 6 filled triangles respectively. The method of the invention is not only applicable to triangles with multiple line widths, but also applicable to drawing polygons with arbitrary line widths.

[0019] figure 1 Divide schematics for multi-linewidth triangles. Usually, when drawing a multi-line width triangle, the line width of the triangle and the outer vertex of the triangle are given, so the inner vertex of the triangle needs to be calculated first. Assume that the outer three vertices of the multi-line width triangle are (x min ,y min ), (x mid ,y mid ), (x max ,y max ), the width of the sides of the triangle is d. Among them, the outer three vertices of the t...

Abstract

The invention discloses a distortion-free drawing method of a head up display multi-line-width triangle, and belongs to the technical field of graphical display. In order to solve the problem that the display of three vertexes is subjected to serious distortion when a traditional head up display multi-line-width triangle is spliced and drawn by three multi-line-width straight lines, the multi-line-width triangle is divided into six independent filling triangles according to three vertexes on the outer side and three vertexes on the inner side, and each filling triangle is realized by a horizontal straight line filling way. Six filling triangles can be spliced to obtain the multi-line-width triangle of which the vertexes are free from distortion. The method can realize the distortion-free drawing of any-line-width triangles, is simple, has a good display effect and is convenient for hardware implementation.

Description

technical field [0001] The invention relates to a distortion-free drawing method of a head-up display multi-line width triangle, which belongs to the technical field of graphic display. Background technique [0002] Triangles are one of the most basic elements of computer graphics. In many display systems, triangles with arbitrary line widths need to be drawn. A common method for drawing a triangle with multiple line widths is to draw three straight lines with multiple line widths, and splicing the straight lines with multiple line widths to obtain a triangle with multiple line widths. This method is simple and convenient to implement, but there will be serious distortion at the three vertices of the triangle. When the display background is bright, it is necessary to add black borders to the multi-line width triangle. At this time, the distortion of the triangle vertices is more obvious. How to quickly and easily draw multi-line width triangles without distortion has becom...
