Yn=k2∗Ye+b2 Zn=k3∗Ze+b3 三个方程的函数图像如下图所示: 其中: l:视锥体左平面,r:视锥体右平面 b:视锥体下平面,t:视锥体上平面 n:视锥体近平面,f:视锥体远平面
Alternatively, you can upload the vertices in world space to the GPU's memory. In this case, alongside the projection matrix (commonly denoted as P or Proj), the shader also needs the world-to-camera transformation matrix (often labeled M or MV, where MV stands for "model-v...
