Detailed Description

Structure for specification of triangle locator information. data specify barycentric coordinates for specified triangles. Indices are retrieved through selection streams during location process. Baricentric locator defines vertex positions in barycentric coordinates of a triangles. Only U and V coordinates are stored because W is always 1-U-V.
