This operator returns the relative position of the point given with with respect to the bounding box of the specified geometry. This is equivalent to getting BBX, BBY, BBZ in the Point SOP.
If no position is given, the global
P variable will be used instead.
In some contexts this may be an error if no such variable has been bound.
If no file is given, the first input is used where applicable.
Because this uses primitive bounding boxes, the group is a primitive group. Primitive bounding boxes include the extents of primitives such as spheres and volumes.
op:/ syntax can be used to refer to a SOP operator rather than a file on disk.
The file on disk to find the relative bounding box location in.
The subset of primitives to use for computing the bounding box.
Uses SOP-style syntax, so an empty string means all primitives,
and adhoc groups such as
@Cd.x>0 can be used.
