pcline_radius

Since	18.0

int [] pcline_radius(<geometry>geometry, string PChannel, string RadChannel, float radscale, vector P, vector dir, float max_distance, int maxpoints)

int [] pcline_radius(<geometry>geometry, string ptgroup, string PChannel, string RadChannel, float radscale, vector P, vector dir, float max_distance, int maxpoints)

<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.

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.
