Perspective division on clip coordinates yields normalized device coordinates, followed by a viewport transformation (see section 13.6.1) to convert these coordinates into window coordinates. OpenGL does the perspective divide as device.xyz = gl_Position.xyz / gl_Position.w But then keeps the 1 / gl_Position.w as the last component of gl_FragCoord: Web28 de ago. de 2024 · 但是 PCF 算法的圆盘半径大小是固定的，因此处处的边缘看起来都带有相同的渐变范围，这和我们看到的笔尖阴影现象不符合（近处边缘渐变应该更少些，远处边缘渐变应该多些），所以我们可以只要根据不同位置动态地修改圆盘半径大小（实际上就是动态地计算 \(w_{Penumbra}\) ），这个也就是PCSS的 ...
