I have used RayPick method (IDirect3DRMFrame3 interface)
in order to calculate distances from a plane to a
dynamically generated land (very mountainously). This land
has acute edges, and when the RayPick method is directed
against one of these edges, it never find any object (the
LPD3DRMPICKED2ARRAY has zero size). Does anybody know what
is the matter? I think it is related with the normals in
the land faces.
Thanks and greetings.
