[1] Introduction



This is a Scheduler sample program.  The scheduler used in this 

sample program was developed by the NINTENDO64 TECHNICAL SUPPORT 

CENTER, and it incorporates the general scheduler functions.  

This sample program contains imporvements and additions to the 

general scheduler that make it more efficient.



[2] Using make



Whether using the Indy emulator board or PARTNER-N64, please 

execute make without any additions.



[3] Control operations



	Control Stick        	Up/Down to rotate depth-wise, 

                            	Right/Left to rotate in the X-Y 

				plane.

	Control Pad Up    	Bring viewpoint toward origin.

	Control Pad Down     	Recede viewpoint from origin.  

	Control Pad Right    	Not used.

	Control Pad Left     	Not used.



	A button             	Shoot bullet.

	B button             	Not used.



	C button             	Rotate around center of viewpoint.

	

	START button         	Switch between fighter screen and 

                             	Controller model screen.



	Z button             	Change precedence of graphic 

				threads (only while pressing 

				button).  For a detailed 

				explanation, see the source file 

				graphic_01.c.  



	L/R buttons          	Not used.



* The above manipulations are for the fighter plane screen.  

Operations for the Controller model screen have been omitted.  





[4] Explanation of the screen



(1) Number of polygons for the model



Fighter No.1 (Blue) 314 Triangles

Fighter No.2 (Red)  314 Triangles



(2) How to read the performance meter



Starting from the left, the performance meter shows the first 

frame, second frame and third frame.  Measurements are made based 

on the time it takes to create the screen for 1 frame buffer.  

Each meter provides the following information: 



Red    ... Time for audio task processing. 

Green  ... Time for RSP processing of the graphic task.

Yellow ... Time for RDP processing of the graphic task.



* RSP processing time includes the time yielded by the audio task. 



(3) Screen rendering



To render the screen, these three graphic tasks are run in 

frame 1: 



	1. Clear the frame buffer and Z buffer (F3DEX microcode). 

	2. Render opaque polygons (F3DEX microcode). 

	3. Render lines (Linde3D microcode). 



The task of clearing the frame buffer and Z buffer is separated 

from the task of rendering opaque polygons because the former 

task makes use of time when the CPU is creating the audio task.
