## Public Attributes
RtFloat | u1
| U baricentric coordinates.
RtFloat | v1
| V baricentric coordinates.

## 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.
