POV-射线粘土纹理
有谁知道如何在 POV-Ray 中模拟粘土纹理?也喜欢一些可以创造出具有粘土粗糙度的物体的东西。是否有某种数学函数可以产生粘土平滑的随机凹凸?
Does anyone know how to simulate a clay texture in POV-Ray? Would also love something that could create an object that has the roughness of clay. Is there some sort of mathematical function that can produce a clay smooth random bump?

如果你的字面意思是 povray 定义的“纹理”,我帮不上什么忙。但是,如果您想要一个表面看起来像光滑凹凸的对象,请尝试研究斑点对象,或者可能是noise3d 函数。

If you literally mean "texture" as povray defines it, I'm not much help. But if you want an object whose surface looks like smooth bumps, try investigating the blob object, or perhaps the noise3d function.
