Houdini 12 Nodes Surface nodes

Computes analytic properties of volumes.

The Volume Analysis operation computes analytic properties of the volumes, such as the gradient and curvature. This is done in the local space of the volume. These are a function of more than one voxel so are more difficult to compute inside a Volume VOP.

Where possible, these operations occur in place and preserve the name. If new volumes have to be created, it is attempted to ensure they gain the .x, .y, .z style suffixes in their name attribute.

Parameters

Source Group

The volume primitives to be analyzed.

Analysis
