摘要
地形渲染一直是计算机应用领域内的关注热点,是因为其渲染效果和渲染速度两者不能同时得到解决好。采用的基于四叉树的LOD技术就是:先借助于四叉树思想对地形进行分割好,然后利用LOD技术进行渲染,而在渲染过程中不同精度的地形格网间出现的T型裂缝也做了相应的消除处理,最后这样渲染出的地形效果比较真实理想,且其渲染速度也有所提高。通过此技术方法可以实现,在保证真实地渲染出地形效果的前提下,尽量减少地形的渲染面数,来达到提高渲染速度的目的。
Three - dimensional terrain generation is a hotspot in computer application at all times, because the effect of generation and the rate of generation can＇ t be solved weft in the mean time. The method of LOD based quad - tree is ： firstly by dim of the quad - tree ideas to divide up terrain, then using the LOD to romance and to eliminate the T - cracks that will appear in different precision＇ s terrain during romancing, finally the terrain effect of generation is quite real and the rate of generation is quick. This technical method can realize the purpose to increase the rate of generation by reducing the number of the faces on the premise of the real terrain effect.
