This operator returns two vectors representing the minimum and maximum corners of the bounding box for the specified geometry.
This generates a primitive bounding box, so primitives like spheres and volumes will expand it to include their extents.
If no file is given, the first input is used where applicable.
op:/ syntax can be used to refer to a SOP operator rather than a file on disk.
The file on disk to compute the bounding box of.
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.
