Hi everybody!

I am looking for a way to find the closest objects to a point (with a distance under a certain threshold).

I used to have something similar in Rhino 5 defining the pick_context.m_pick_region.m_xform equal to the inverse of an Xform defining a custom hexahedron. Unfortunately this method was not robust for objects crossing this hexahedral area and the pick_context.m_pick_region.m_xform is private in Rhino6.

Is there a solution that allows me to have this list without iterating on all objects to find the distance from the point?

I ask it because I assume that Rhino have access to an internal spatial indexing of the objects, so I expect its functions to be faster.

Thanks

G.
