makai Posted November 26, 2012 Share Posted November 26, 2012 Hi guys! I'm working on a project in which we are simulating an energy field flowing over a surface and geometry. I could *theoretically* make a line emitter and animate it by hand when it collides with the objects, but I forsee much hassle in that route. So I'm thinking that making the line collide with the geometry would be easier. Attached is a photo of a simple, simple setup. I want this line (and points) to collide and deform when it meets the geometry, to flow over it like a thick blanket. Would it be better to approach it as a cloth simulation? If so, how do I get the cloth to be points instead of, well, cloth? Thank you so much! Miriya Quote Link to comment Share on other sites More sharing options...
Annon Posted November 27, 2012 Share Posted November 27, 2012 (edited) You could simply use the ray sop if you wanted, or even the attribute transfer sop set to transfer "P". For a bit more control I'd use an SDF to act as your "collision" object (not really a collider as you don't need to simulate) and in a VOPSOP use the "Volume Sample" and "Volume Gradient" to push the points outward towards the edges. Give it a nice rolling falloff etc... ray.hip Edited November 27, 2012 by ChristianW 1 Quote Link to comment Share on other sites More sharing options...
makai Posted November 27, 2012 Author Share Posted November 27, 2012 Wow thank you! That really helped a lot! And it will probably save me a ton of render time. Thanks again! Quote Link to comment Share on other sites More sharing options...
