Description
Finds the first location on a surface that is hit by a ray cast from a given position in a given direction. The Proximity Method parameter specifies how the ray is interpreted:
Parameters
|
Proximity Method |
Method used to compute the proximity: • Semi-line shoots an infinite ray in one direction. • Line shoots a ray in both directions. • Segment shoots a ray in one direction and is bounded by the length of the direction vector. |
Ports

|
Cutoff Distance |
Distance within which to look for ray hits. |
Outputs
