float volumeindex(<geometry>geometry, int primnum, vector voxel)
float volumeindex(<geometry>geometry, string volumename, vector voxel)
<geometry>
When running in the context of a node (such as a wrangle SOP), this argument can be an integer representing the input number (starting at 0) to read the geometry from.
Alternatively, the argument can be a string specifying a geometry file (for example, a .bgeo
) to read from. When running inside Houdini, this can be an op:/path/to/sop
reference.
The value of a specific voxel in a volume primitive.
Returns 0 if primnum
is out of range, the geometry is invalid, or the given primitive is not a volume primitive.
