Road condition drawing method, related device and client

Abstract

The invention discloses a road condition drawing method, a related device and a client. The method comprises the following steps: determining the width of a road condition texture required to be intercepted from a preset road condition texture template according to the preset road texture template; according to the width, intercepting the road condition texture with the corresponding width from the road condition texture template, wherein the intercepted road condition texture comprises a road condition color value; and mapping the intercepted road condition texture to a position corresponding to the end part of the road to be drawn. The width of the road condition width texture matched with the to-be-drawn road can be dynamically adjusted according to the actual road drawing requirement, so that the phenomenon of hollowness between the road width and the road condition width in the prior art is avoided, and the map graphical display effect is improved.

Description

technical field [0001] The present invention relates to the technical field of computer graphics processing, in particular to a road condition drawing method, a related device and a client. Background technique [0002] The rendering pipeline, also known as the rendering pipeline, refers to a series of processing processes that the rendering screen needs to go through. Rendering pipelines can be divided into two categories, one is fixed pipelines and the other is programmable pipelines. [0003] The fixed pipeline does not require and does not allow customizing the specific logic of vertex rendering and pixel rendering. It has solidified a complete rendering process inside. An example of a fixed pipeline rendering process generally includes the following functions: [0004] 1. Vertex Transformation; [0005] 2. Primitive Assembly and Rasterization; [0006] 3. Fragment Texturing and Coloring; [0007] 4. Raster Operations; [0008] The programmable pipeline allows progr...

Problems solved by technology

[0012] When the fragment shader is processing the rendering process of the map road conditions, when the scale of the map is changed, the road condition graphics and the road graphics do not fit well, resulting in jagged or hollow effects.

[0013] In addition, in the map rendering process, if you want to render irregular shapes (called abnormal shapes), in the actual processing process, you usually use more complex methods to perform calculations, such as using a large number of Boolean operations. On the one hand, it lacks flexibility. On the other hand, there are also situations where the execution efficiency is low or the graphics effect is not good during the graphics drawing process
