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.
