System.double IGetVertexParams( 
   System.int VertexId
)

System.double IGetVertexParams( 
&   System.int VertexId
) 

Parameters

VertexId

ID of the tessellation vertex for which you want to the parameters

Return Value

• in-process, unmanaged C++: Pointer to an array of contains 17 doubles (see Remarks)

The following parameters returned from this method are formatted as an array of 17 doubles:

• u, v - location of the vertex on the face (retval position [0-1])

• du - tangent vector at u (retval [2-4])

• dv - tangent vector at v (retval [5-7])

• d2u, dudv, d2v - curvature vectors for u and v (retval [8-16])
