vector getpointbbox_min(<geometry>geometry, string pointgroup)
This is the same as getbbox_min except it only computes the bounding box of the points. So if a primitive has extents that don’t have points (for example, the boundary of a primitive sphere), they will not be included in the box.
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
