# bot_face_sort

Sorts the list of triangles that constitutes the BOT primitive to optimize it for raytracing with the specified number of triangles per piece.

          bot_face_sort
           triangles_per_piece
           bot_primitive1>
           bot_primitive2 bot_primitive3

## DESCRIPTION

Used to sort the list of triangles that constitutes the BOT primitive to optimize it for raytracing with the specified number of triangles per piece. Most BRL-CAD primitives are treated as a single object when a model is being prepared for raytracing, but BOT primitives are normally broken into "pieces" to improve performance. The raytracer normally uses four triangles per piece.

## EXAMPLES

The example shows the use of the `bot_face_sort` command to sort the list of triangles that constitutes the BOT primitive to optimize it for raytracing.

### Sorting the faces of two primitives (each having four triangles per piece) to optimize them for raytracing

mged> `bot_face_sort 4 bot1 bot2`

  The faces of bot1 and bot2 to optimize them for raytracing with four triangles per piece.
