int inprimgroup(<geometry>geometry, string groupname, int primnum)
<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.
Returns
1
if the groups exists and the primitive is in the group, or 0
otherwise.
This can use ad-hoc groups, like 0-3
or @Cd.x>0.5
. It matches the SOP
group naming convention, in particular that an empty string means all
primitives.
