volumeindexv

vector  volumeindexv(<geometry>geometry, int primnum, vector voxel)

vector  volumeindexv(<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.

Returns

The vector value of a specific voxel in a volume primitive.

Returns 0 if primnum or inputnum is out of range, the geometry is invalid, or the given primitive is not a vector volume primitive.
