Laplacian Filter (HDA) Sept. 14, 2025, 4:56 a.m.

The new Laplacian node [www.sidefx.com] can be used to make a geometry equalizer.

Like with sound, you can exaggerate or reduce certain frequencies (eigenvectors) of the geometry. This can be used to reduce or increase detail in certain areas, for a variety of distortion effects.

Thanks to @WhiteDo27114277 for his Eigenspace Projection example [drive.google.com]! I remade it in OpenCL for better performance.

"Remeshing" simple CAD geometry Sept. 7, 2025, 7:45 p.m.

This is a cool tool, great work!

You might be able to use Labs Dissolve Flat Edges for the first part of it:

Repair Cycles (HDA) Sept. 7, 2025, 1:30 a.m.

KineFX often whinges when skeletons are cyclic ("Cycle Detected" errors). There's a good section on CGWiki [www.tokeru.com] to fix this, but it only works if there truly aren't cycles.

If the skeleton actually has cycles, you need to detect and repair them. I made a HDA for this purpose (I'm not sure why this isn't built into Houdini to be honest)

It can mark, split or remove cycles. Marking cycles can help for other graph traversal problems too.
