getpointbbox

void  getpointbbox(<geometry>geometry, vector &min, vector &max)

void  getpointbbox(<geometry>geometry, string pointgroup, vector &min, vector &max)

This is the same as getbbox 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.

<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.
