emitter driven by angle on edges. 2005-05-12 - By Pingo
Back
ok, don't quite know how to ask this question, so here's an example...
say I got a grid that deforms... like an ocean surface. so there's
waves with ridges and slopes.
Now I want to emit particles if the angle on an edge is larger
than... say 180 degrees - so where ever the waves are sharp
there's... foam.
I'm kinda looking for something like what the dirt shader does, only
inverted, but it doesn't quite do what I want it to do... not even
sure I can use it to drive an emission...
I'm also assuming I need something that can drive a weight map... So
can I get XSI to calculate the angle on edges (or between polygon
normals... something) and make the map?
anyone?
cheers all!
