(GT-3D-SWAP-TRIANGLE) (SEND <gtm:terminal> :3D-SWAP-TRIANGLE)
The driver internally remembers the last two positions of the 3D cursor, along with their associated colors. This call reverses the remembered order of the last two positions, along with the colors. Useful when drawing a triangle mesh.
This is a new-style 3D call. Use of this call is strongly discouraged, however, and it may be phased out shortly. Build a GRAPHIC-RELATION and draw it with a :DRAW message to a camera, instead.
