Introduction
     This program is a sample of the scheduler program.  The scheduler 
     used in this sample program was developed by the Nintendo 64 Technical 
     Support Center and has the usual scheduler functions.  It can be 
     improved and expanded to function with reasonably good efficiency, 
     so please use this scheduler as a reference.   


make
     Use make with with either the Indy Emulator Board or Partner-N64NW.  
     It is used without changes to either device.   

     Note: (1) The F3DEX microcode must be used with this sample program.
           (2) The comments in the source file use Shift-JIS encoding.  

Operation

     Control Stick up or down rotates in depth direction, left or right 
     rotates in the X-Y plane   

	Control Pad up......Moves viewpoint toward home position 
	Control Pad down....Moves viewpoint away from home position
	Control Pad right...Not used
	Control Pad left....Not used

	A Button............Fires shots
	B Button............Not used
	C Button............Rotational movement centered on home position of viewpoint 
	START Button........Switch between Fighter screen and Controller model screen

	Z Button............Change graphics thread priority order
			    only while button pressed for details,
			    see the graphic_01.c source file.  

	LR Buttons..........Not used

     The operation described above is for the Fighter screen.
     Operation of the Controller model screen has been omitted. 

Screen Description

     (1) Number of Polygons in Models

               Fighter No. 1	blue):  314 Triangles
               Fighter No. 2	red):   314 Triangles

     (2) Performance Meter Perspective

         The Performance Meter frames are the first, second, 
         and third frames from the left.  The meters are as follows.  

               Red	 Processing time for audio tasks 
               Green	 RSP processing time for graphics tasks
               Yellow	 RDP processing time for graphics tasks

         Included in the RSP processing time is YIELD time resulting 
         from audio tasks.

     (3) Screen Rendering

         With screen rendering, the following 3 graphics tasks 
         are initiated for each frame.   

          1. Clearance of the frame buffer and Z buffer (F3DEX microcode)
          2. Rendering of opaque polygons (F3DEX microcode)
          3. Line rendering �i(Line3D microcode)

          Frame buffer and Z buffer clearance and opaque polygon 
          rendering are separated because they are performed 
          during the time the CPU creates audio tasks.
