	SAMPLE PROGRAM FOR ROUND MESH FUNCTION(RotMeshPrimR_?)
	

<Description>
	
	This sample program performs following:
	 - Applies coordinate conversion and perspective conversion to the 2 dimensional
           mesh data.
         - Generates packets.
         - Link to OT.
	The round mesh data is specified by the structure "TMESH".

	In Figure 1,
		len = 6
		v,n,u,c are arrays with elements in order as above figure 1.

	The tuto0 displays various modes at one time.
	The number of the polygons displayed is fixed.
