OnSurfacePick method

Determines whether any part of the surface is located at the specified point.

Syntax


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

Parameters

OutPoint [ref]

Type: const CDXDBnds

Coordinates of the point on the output surface to test.

ulInputIndex [ref]

Type: unsigned long

Not used for procedural surfaces.

InVec [ref]

Type: CDXDVec

Not used for procedural surfaces.

Remarks

Procedural surfaces can only know if there is a sample located at the specified point. There is no input surface to map the point back to, so ulInputIndex and InVec should return NULL.
