深入探索透视投影变换
摘要:深入探索透视投影变换引用自:原文(作者:Twinsen)-Twinsen编写-本人水平有限,疏忽错误在所难免,还请各位数学高手、编程高手不吝赐教-email: popyy@netease.com透视投影是3D固定流水线的重要组成部分,是将相机空间中的点从视锥体(frustum)变换到规则观察体(Canonical View Volume)中,待裁剪完毕后进行透视除法的行为。在算法中它是通过透视矩阵乘法和透视除法两步完成的。透视投影变换是令很多刚刚进入3D图形领域的开发人员感到迷惑乃至神秘的一个图形技术。其中的理解困难在于步骤繁琐,对一些基础知识过分依赖,一旦对它们中的任何地方感到陌生,立刻导致 阅读全文
