Problems solved by technology

Most of today's electronic devices have a display screen of more than one million levels. During the real-time rendering process, a large number of pixel processing units in the GPU will significantly affect the performance of 3D games.
[0005] It can be seen that in the existing bulletin board rendering method, since many redundant transparent pixels need to be calculated, it will lead to the problem of high GPU computing overhead and low rendering efficiency

Embodiment Construction

[0021] In order to make the purpose, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0022] The core idea of ​​the present invention is: use "Graham's scanning method" to determine the minimum convex polygon point set used to construct the bulletin board texture, so that the area of ​​the transparent area on the bulletin board texture can be greatly reduced, thereby greatly reducing the calculation Resource overhead, improve rendering efficiency.

[0023] figure 2 It is a schematic flow diagram of the method of the embodiment of the present invention, such as figure 2 As shown, the rendering method of the bulletin board implemented in this embodiment mainly includes:

[0024] Step 201, using the minimum convex hull Graham scanning method in advance to construct a corresponding polygonal graphic data structure for the ...

Abstract

The invention discloses a bulletin board rendering method and a device. The bulletin board rendering method comprises steps of adopting a small convex hull Graham scanning method to construct a polygonoun figure data structure for an original plaster of a bulletin board, and drawing a corresponding bulletin board according to the polygonoun figure data structure when the system is needed to load the plaster of the bulletin board. The invention can greatly reduce the calculating resource expenditure and improves the rendering efficiency.

Description

technical field [0001] The invention relates to computer graphic image processing technology, in particular to a bulletin board rendering method and device. Background technique [0002] In the development process of the 3D game system, in order to achieve high-quality picture effects, a large number of fine art resources are used in the game scene. However, the game system is different from 3D movies in that while pursuing image quality, it also requires the smoothness of real-time rendering after adding logic control to reduce the computing overhead of CPU and GPU. Therefore, real-time rendering optimization technologies such as art resource optimization, engine optimization, code optimization, and shader optimization are very important. [0003] Bulletin board technology is an art resource optimization technology. In the existing bulletin board rendering method, a rectangle composed of two triangles is used to display a rectangular plane bitmap, and during the scene dis...
