Plate Project (HDA) Oct. 26, 2025, 8:02 a.m.
NDC coordinates [github.com] are great for projecting plates (photos and videos) from the camera that took them, or Ian Hubert projection tricks [www.youtube.com].
This HDA lets you project plates in 3 ways:
1. Constant Z coordinate

2. Varying Z coordinate using a depth map

3. Raying onto the object

The Laplacian can also be used to produce a straight skeleton, with similar results to Labs Straight Skeleton but much faster:

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.
