laplacian deformation?

Recommended Posts

Has anyone created a "laplacian" deformer in Houdini? Or maybe some of the current deformation techniques use this under the hood?  Blender has this and it looks interesting:

seems similar to Delta Mush SOP

Hmm, Probably is. It's also similar to the Edit sop when using a smooth radius by connectivity. But I'm interested in seeing how this works as a live deformer, not an interactive sculpt.  I'll see if I can do it with delta mush

After playing with the deformer in Blender, it's quite different than Delta Mush. A bit hard to describe but it almost feels like it creates an ik relationship between all the edges in the mesh.. with just anchoring a couple of verts on either side of a mesh and pulling them apart it smoothly interpolates the verts between them using the connectivity of the mesh in a natural way.  There is code for the deformer on the Blender repository, might be worth trying to port

You have an example on odforce I think somewhere :)..

If you combine you can make a better tool.

Just install Anaconda python:) ..and you have a lot exampels for deformation and other fun..
