How use volumes to detect collision in sop and deform July 3, 2017, 4:40 a.m.
I don't know vex but want learn how use it! 
Yes, I should use a sdf collision, with vop I can use a twoway and a compare to create a if operation, can I import automatically groups information from the opinput, right? or a import point group or bind.
Thank you for your feedback jsmack!

How use volumes to detect collision in sop and deform July 1, 2017, 5:07 p.m.
Hey guys, sorry for my english
There is a way in Houdini to detect the collision and have a organic style deformation without dynamics to avoid the intersection of the meshes? I have some geometry groups (tentacles based on curves) in a single object, so, I thinks is possible with volumes and a vex expression with if and else, but I'm not so good with vex, i'm still learning. So, using a foreach loop , maybe converting the mesh into volumes and use a scatter to have the surface and inside points to detect their position, how can I import in a wrangle the groups and their points info to create this type of action?
I know the message but i don't know how to write it, some ideas?
Thank you
