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