Abstract

The invention discloses a 3D game engine LOD system achievement method. The achievement method mainly includes the steps that a scene to be drawn is imaged to be a large terrain block, and the terrain block is divided into terrain block bodies in the specification of M*N, wherein M and N are both natural numbers; the vertex height value of each terrain block body is raised or reduced, namely the Y value of the vertex of each terrain block body is changed, the uneven terrain block is produced, and in the terrain coordinates XOZ, check terrain block bodies, namely terrain checks, corresponding to the plane where the terrain block is located are overlooked; a scene graph with a low resolution ratio is drawn according to different scenes, produced along with moving of a camera, of each terrain block body. According to the 3D game engine LOD system achievement method, the defects that in the prior art, model precision is low, terrain graphs are difficult to draw and rendering efficiency is low are overcome, and the advantages that the model precision is high, the terrain graphs are not difficult to draw and the rendering efficiency is high are achieved.

Description

technical field [0001] The invention relates to the technical field of 3D game and panorama roaming development, in particular to a method for realizing a 3D game engine LOD system. Background technique [0002] Video games are one of the most popular entertainment and leisure methods nowadays, and with the development of video games for more than 30 years, more and more realistic 3D graphics game engine technology has become the top priority in today's game field, and graphics The optimization scheme of technology in operation processing has become an important link that directly affects the development of games. In order to ensure the smooth output frame rate of 3D graphics images under the current computer computing capabilities, various optimization methods for 3D graphics effects are game engines and graphics technologies. One of the research focuses of developers. [0003] LOD technology is the abbreviation of Levels of Detail, that is, multi-level of detail. This tec...
