VEX Volume Deform SOP (Patreon)

Deforms volumes using a point cloud that can optionally have connectivity information where connected points are used to deduce local transforms, allowing accurate transformation of rotating geometry.

It supports the deformation of scalar, vector and matrix volumes, both VDB and standard volume primitives. For VDB vector volumes; tuple, color, UVW and position volumes are handled differently than gradient, normal, unit normal, displacement, velocity and acceleration volumes.
