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.
These functions open a geometry file and return a list of points (treated as spheres) within ‹max_distance› of the line passing through ‹P› with direction ‹dir›. Each point is treated as a sphere with radius equal to its ‹RadChannel› attribute,
The ptgroup
is a point group that limits the points to search. This is a SOP-style group pattern, so can be something like 0-10
or @Cd.x>0.5
. A blank string is treated as matching all points.
