@m_adam Oops. Okay, GeRayCollider works only for polygon objects, as does GetPixelInfoPolygon.
The idea was to provide a new selection method for arbitrary objects by just checking all hits of a scattered PickObject within a radius, and then select the nearest hit. For that, I need to be able to hit splines and parametric objects as well.
Okay, I guess I can still do that in C++ then, thanks.
