飞行模拟器视景中纹理压缩技术的研究与实现

在不增加纹理内存的条件下，纹理压缩技术是提高纹理容量的一种有效方法。本文详细介绍了纹理压缩的基本算法及其4种改进算法，并以表格方式给出了纹理压缩前和压缩后的对比结果，最后分析了飞行模拟器视景所使用的各种纹理，说明如何在实际应用中针对不同纹理使用不同的纹理压缩算法。

Research and Realization of Texture Compression in Flight Simulator Visual Scene

Texture compression is a powerful way to increase the amount of texture without increasing the texture storage requirements. This paper introduces a basic texture compression algorithm and four improved algorithms in detail. Then, a comparison of uncompressed textures and compressed textures is shown in a table. In the end, the author analyses all kinds of texture used in flight simulator visual scene in general and points out how to use different texture compression algorithm to the different textures in practice.
