Embodiment Construction

[0040] The method will be further described below in conjunction with the accompanying drawings.

[0041] The main steps of the three-dimensional game terrain generation method of the present invention include: a preprocessing process, a node evaluation process and a real-time processing process. As shown in Figure 1, the process of the entire algorithm is as follows: firstly, the terrain data is read from the hard disk, and then the terrain data is sampled and converted into data stored in another data format through the preprocessing process, and then when the terrain is rendered, The real-time processing process will render the terrain in real time according to the evaluation of the details of the terrain nodes in the node evaluation process, and finally repair the cracks generated during the terrain rendering.

[0042] The following is a detailed introduction to each step:

Abstract

The method includes three procedures: pretreatment procedure, node evaluation procedure, and real time processing. The method includes following steps: reading geography data from hard disk; next, through pretreatment procedure, converting sampled geography data to data to be stored in another data format; then, when rendering topography, the real time processing procedure carries out rendering topography in real time based on evaluation on detailed degree of topography node by the node evaluation procedure; finally, repairing cracks generated in rendering topography. Optimizing traditional geomorphic algorithm, the invention raises generating efficiency and speed, enhances variability of geography in game scene.

Description

technical field [0001] The invention relates to a terrain development method for a three-dimensional game, in particular to a method for generating medium and large terrain in a three-dimensional game running on a PC platform. Background technique [0002] It is a general trend for games to develop in a three-dimensional direction. In three-dimensional games, especially in three-dimensional online games, a large number of characters interact in one scene at the same time, which requires efficient character generation algorithms and scene generation algorithms. An efficient dynamic generation algorithm of large-scale terrain is one of the crucial factors for the quality of a 3D game interface. At present, most of the large-scale terrain rendering algorithms are applied to geographic information systems, virtual reality systems, etc., and there are relatively few practical algorithms applied to games. The present invention aims at the problem of how to efficiently realize lar...
