  No.

  Actually it should be more or less trivial to converts bicubic patches
to meshes because POV-Ray does that internally with type 1 patches.
However, I'm not aware of an include file or similar which would do this.

  Chris Colefax's pcm macros can place objects on the surface of a
bicubic patch. Perhaps it could be easily modified so that it could
create triangles.
