Embodiment Construction

[0020] A batch drawing method for static models. First, the scene is divided into blocks to ensure that only this part of the terrain is visible in the current plot; within a certain range, the vertex flow is established according to the texture, and then the vertex flow is selected according to the field of view. Rendering optimization; its steps include:

[0021] (1) First divide the scene into blocks to ensure that only this part of the terrain is visible in the current block;

[0022] (2) According to the block and texture, the vertex flow is respectively established for the static model of the current plot to ensure the independence of the visibility of the current plot;

[0023] (3) When drawing, first perform hardware query based on the graphics card, find out the static model that is not visible in the current plot, and set its alpha to transparent.

[0024] (4) According to the field of view, set the farther static model to be transparent;

[0025] (5) For the terra...

Abstract

The invention relates to the technical field of computer graphics, in particular to a batch rendering method for static models of a terrain system. The invention has the advantages that the batch rendering method is combined with the hardware query technology, LOD (Level Of Detail) technology and the static batching technology, and also optimizes the rendering of invisible objects, namely, the batch rendering method sets transparent objects instead of rendering the visible and invisible objects at a time in the conventional mode or disconnecting the static flow for separate rendering, on one hand, the rendering times is not increased, a static vertex has no need to be changed, on the other hand, the loss in rendering is also reduced.

Description

[0001] technical field [0002] The invention relates to the technical field of computer graphics, more specifically, to a method for drawing static models in terrain systems. Background technique [0003] Static model is an important part of computer rendering simulation at the present stage. Static models are defined relative to skeletal models. The vertices of the static model have no skinning, and the corresponding animation only has vertex animation. Houses, stones, etc. that must be in a scene belong to the category of static models. [0004] As the requirements for rendering effects continue to increase, the need for static models becomes more and more. The advantage of this is that the effect of the game scene becomes more and more gorgeous, but due to the relative lag of hardware development, when making static models, the rendering pressure of the computer has to be considered. [0005] For the frame number optimization of static drawing of a large number o...
