这是对 MIT.Foundation of 3D Computer Graphics第11章的翻译,本章讲解了投射矩阵中深度比较的相关知识,重点讲解了3D投射矩阵的形成和应用。本书内容仍在不断的学习中,因此本文内容会不断的改进。若有任何建议…
在OpenGL中一个3D场景需要被投影到屏幕上成为一个2D图像(image)。这称为投影变换(参见这或这),需要用到投影矩阵(projection matrix)。 首先,投影矩阵会把所有顶点坐标从eye coordinates(观察空间,eye space或view space)变换到裁剪坐标(clip coordinate,属于裁剪空间,clip space)。然后,这些裁剪坐标被变换到标准化...

World Matrix (objectToWorldMatrix) Transforms object space vertices to world space vertices. I like to think of object space as the “artist” space as it is the space that the Artist models there geometry. All the vertices in the model, like a 3D character, are relative to some special...
