    mesh : Mesh,
    adjacencyIn : GraphicsStream,
    numSegs : float,
    quadraticInterpNormals : boolean,
    adjacencyOut : GraphicsStream
) : Mesh;

Parameters

mesh Microsoft.DirectX.Direct3D.Mesh
A Mesh object that represents the mesh to tessellate.

adjacencyIn Microsoft.DirectX.GraphicsStream
A GraphicsStream containing three Int32 values per face that specify the three neighbors for each face in the source mesh.

numSegs System.Single
Number of segments per edge to tessellate.

quadraticInterpNormals System.Boolean
Set to true if quadratic interpolation for normals is used. Set to false if linear interpolation is used.

adjacencyOut Microsoft.DirectX.GraphicsStream
A GraphicsStream containing three Int32 values per face that specify the three neighbors for each face in the output mesh.

Return Value

Microsoft.DirectX.Direct3D.Mesh
A Mesh object that represents the returned tessellated mesh.
