	SAMPLE PROGRAM FOR 2 DIMENTIONAL MESH FUNCTIONS(RotMeshPrimQ_T)	

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

	typedef struct {
   	SVECTOR         *v;         /*shared vertices*/
        	SVECTOR         *n;         /*shared normals*/
        	SVECTOR         *u;         /*shared texture addresses*/
        	CVECTOR         *c;         /*shared colors*/
        	u_long          lenv;       /*mesh length_V(=#vertex_V)*/
        	u_long          lenh;       /*mesh length_H(=#vertex_H)*/
	} QMESH;

			Structure "QMESH"

	Above,
		lenv = 4
		lenh = 9
		v,n,u,c are arrays with elements in order as above figure.

	In the sample program tuto0 has;
		lenh = 42
		lenv = 43
	In the sample program tuto1 has;
		lenh = 42
		lenv = 46
	
	lenh must be a multiple of 3 since functions with the 3 vertices concurrent
        calculations are used.
        
      	RotMeshPrimQ_T is only for the texture mode and the light calculation will not 
        be done except for the depth queuing. Thus n,c in QMESH will be ignored.
       
	RotMeshPrimQ_T can perform the screen clipping that does not draw polygons        
         outside a clipping area. 
	"tuto0" sets the clip area somewhat smaller than the screen size making the 
         clipping	process easier to see.
	"tuto1" matches the clip area with screen size.

	The number displayed is the calculation time for one frame with unit Hsync.
