* iTexCoords
* The array of texture coordinates.

* iNumFaces
* The number of faces
* iNumVertexPerFace
* Array containing the number of vertices per face.
* iFaceStyle
* Array containing the description style of each faces.
* The style belongs to:
* - TRIANGLE_STRIP: the face indices describe a triangle strip
* - TRIANGLE_FAN : the face indices describe a triangle fan
* - TRIANGLES : the face indices describe single triangles
* If iCopy != 0, the array is copied; you must deallocate iFaceStyle. Else you must not.
* iVIndices,
* Array of vertices indices.
* The integers contained in this array must be multiple of 3.
* If iCopy != 0, the array is copied; you must deallocate iVIndices. Else you must not.
* iVISize
* The size of iVIndices.
* iNIndices
* Array of normals indices.
* The integers contained in this array must be multiple of 3.
* If iCopy != 0, the array is copied; you must deallocate iNIndices. Else you must not.
* iNISize
* The size of iNIndices
* iMIndices
* The Material indices (per vertex)
* iMISize
* The size of iMIndices
* iTIndices
* The Texture coordinates indices (per vertex). The integers contained in this array must
* be multiple of 2. iTISize The size of iMIndices iCopy 0 : the arrays are not copied. The
* pointers passed as arguments are used. IndexedFaceSet takes these arrays deallocation in
* charge. 1 : the arrays are copied. The caller is in charge of the arrays, passed as arguments
