mirHadi Posted October 20, 2015 Share Posted October 20, 2015 hello I have a very simple setup with about 100+ tentacles on a moving thing!... I just want the tentacles collide with each other. seen a few setups here and I think those are fine but very slow, wire solver, (lots of penetration...) in my ugly render, the penetration into each other is not obvious apparently ( in my eye!!!) .. that is the problem and I don't know like lots of thing how to approach to it in Houdini in an efficient way. i'll be more than happy if you can help me with that. thank you very much tentacles.firstRender.rar Quote Link to comment Share on other sites More sharing options...
mestela Posted October 21, 2015 Share Posted October 21, 2015 I know people are moving towards grain/pbd for this sorta stuff, but I've got good results with wires simming lots of colliding curves, not too expensive. I emulated a gross-but-cool worm setup by Sam Hancock, might give you some clues (the example above it is standard wires-on-sphere, similar to your render). http://www.tokeru.com/mayawiki/index.php?title=HoudiniDops#Wire_solver_with_multi_solver Quote Link to comment Share on other sites More sharing options...
mirHadi Posted October 21, 2015 Author Share Posted October 21, 2015 thank you mestela! actually I've seen these examples before... they are good and somehow slow. so for the test I used chops. ( they were in the shadows, no collision, cheater! ) on the other hand, grain/pdb method looks interesting. I'll check it out to see what happens.

mestela Posted October 21, 2015 Share Posted October 21, 2015 (edited) I did a quick test this afternoon with pdb, worked pretty well; after turning on openCL I could sim 80 strands on a sphere, about 4 frames per second. I'll try and tidy it up tonight and post it.

mirHadi Posted October 21, 2015 Author Share Posted October 21, 2015 thankx I'll try this method to see how far I can go with it. Quote Link to comment Share on other sites More sharing options...
Farmfield Posted October 21, 2015 Share Posted October 21, 2015 FEM is speed up a lot in H15, up to 10x SESI say's. Did a quick setup earlier today, it's a lot more useable in regard to tweaking when it sims that much quicker. Quote Link to comment Share on other sites More sharing options...
