Gets the normal vector for each of the triangles, which make up the shaded picture tessellation for this part.

.NET Syntax

Visual Basic (Declaration) 
Function IGetTessTriStripNorms() As System.Single
Visual Basic (Usage) 
Dim instance As IPartDoc
Dim value As System.Single
value = instance.IGetTessTriStripNorms()
System.float IGetTessTriStripNorms()
System.float IGetTessTriStripNorms(); 

Return Value

  • in-process, unmanaged C++: Pointer to an array containing the tristrip normals (see Remarks)
  • VBA, VB.NET, C#, and C++/CLI: Not supported

    See In-process Methods for details about this type of method.

  • Remarks

    The format of the returned data is:

    DWORD FaceCount

    DWORD StripCount

    DWORD (VertexCount) x 3

    DWORD NumStrips

     DWORD [VertexPerStrip] = array from 0 to (Numstrips-1).

    Float [Normals ] = array of X,Y,Z normal components for each strip from 0 to (VertexPerStrip-1).


    FaceCount  = Number of faces on the body.

    StripCount  = Total number of strips on the body.

    VertexCount x 3  = Total number of vertices. Multiplied by 3 to cover X, Y, and Z.

    NumStrips = Number of strips on a particular face.

    VertexPerStrip = Array containing the number of vertex points on particular face strip.

    NormalComp = Array of X,Y,Z normal components for each vertex on the particular face strip.
