Problems solved by technology

Although computer hardware capabilities and rendering technologies have improved, they are still not enough to meet the needs of rendering
Especially in large-scale 3D online games, there are very few terrain rendering resources, and players have increasingly demanding effects, which further accelerates the direct contradiction between effect and efficiency.

Embodiment Construction

[0020] An off-line optimized terrain rendering method, which realizes the optimization of rendering by traversing the positions in the map and determining the visibility of the grid by limiting the reachable location of the current character and the perspective of the character. Its features Is; its main steps are as follows:

[0021] (1) Obtain information about all accessible points of the protagonist in the map;

[0022] (2) Combined with the viewing angle range, determine whether the grid in the viewing range of the character is visible in all viewing directions of each reachable point;

[0023] (3) Store the viewing angle of each point and the visible grid information of the current angle into the point, and the grid information includes all possible visible grids;

[0024] (4) Filter out map grids that are not visible anywhere;

[0025] (5) When drawing the scene, according to the position and perspective of the character, look for the visibility file, perform a visibi...

Abstract

The invention relates to a rendering method, in particular to a method for rendering terrain through offline optimization, belonging to the technical field of computer graphics. The method comprises a step of: (4) filtering useless grids in a map. The method for rendering the terrain through the offline optimization is beneficial to further optimizing a map resource through the arts and reducing the size of the map resource; simultaneously, more collision detection about the terrain is reduced, and the running efficiency of a CPU (Central Processing Unit) is improved, therefore, the fixity of grid information is utilized to the maximum extent, and visible storage is performed in an offline manner; therefore, drawing of the grid is reduced to the maximum extent, and a purpose of increasing the number of frames is achieved.

Description

[0001] technical field [0002] The invention relates to a rendering method, in particular to an off-line optimized terrain rendering method, which belongs to the technical field of computer graphics. Background technique [0003] Terrain system is an important part of computer rendering simulation at this stage, and it has been playing an important role in the production of various large-scale 3D online games and various simulation rendering software. [0004] With the continuous improvement of the rendering effect, the terrain becomes more and more complex, and various rendering techniques appear to improve the rendering effect of the terrain. Such as terrain highlights, terrain shadow drawing, adding surface modifiers, etc. But with the addition of these rendering technologies, terrain rendering has higher and higher hardware requirements. Although the improvement of computer hardware capabilities and the improvement of rendering technology, it is still not enough t...
