does anyone know of a node/shader/method to simulate volume based on the object edges...... like say you have a poly plane, when you render it, it has hard square edges..... I would like it to render as if it was like a flat particle cloud, as if you mapped a ramp to the UV coords, but I would like to do this according to an edge detection (i.e. a samplerInfo.facingCamera wouldn't work cause you still get a hard edge)
I want to create a poly cube and have it render in a cloud like form. I can do it with a sphere (using a samplerInfo node in combination with a ramp), but if I use that approach with a cylinder, then I get hard edges at the open ends of the cylinder.... instead I would like to roll off as the edge approaches.
