Metal Shader Language does however have fwidth (), but it can only be called within a fragment shader. Here is my attempt at porting to a compute shader:
WebMar 2, 2024 · This tutorial is on another common toon shading technique called halftone shading, unlike normal shading it only uses full lit or full unlit as colors, but it doesn’t create a hard cut either. Instead it uses a pattern to decide which pixels are lit and which aren’t and the chance of a pixel being lit gets higher the brighter the pixel would be with a normal … Webfwidth(v) = abs(ddx(v) + ddy(v)) fwidth则反映了相邻像素在屏幕空间上的距离差值. 如:fwidth(pos); 相邻像素位置的差值. fwidth(normal); 相邻像素法线的差值. fwidth(uv); …
