OnSurfacePick method

Called by the base class to enable the derived transform to fully implement surface picking.

Syntax


HRESULT retVal = object.OnSurfacePick(OutPoint, ulInputIndex, InVec);

OutPoint [in, ref]

Type: const CDXDBnds

Coordinates of the point in the transform output space to use for surface picking.

ulInputIndex [out, ref]

Type: unsigned long

Index of the input that was hit.

InVec [out, ref]

Type: CDXDVec

Point on the input that was hit, in terms of the input coordinate space.
