volumeres expression function

Returns the resolution of a volume.

See also: volumesample

surface_node is the full path of the surface node. The prim_id is the primitive number of the volume primitive within the surface node.

axis controls which component of the resolution is returned:

• axis = 0: X-axis

• axis = 1: Y-axis

• axis = 2: Z-axis

Returns 0 if out of bound values are specified, or the given primitive is not a volume.
