Linux is for you to compile your program under Linux with Mesa. SGI is for me to grade your program. To make this system, say using Makefile. Note that the last two items are used for global approximation only. These six values are integers.
All subsequent values are real numbers.
That is, the data points are organized row by row. The current values of u and v are global variables. See draw.c for the details. In general, you perhaps do not need to modify file draw.c , because it includes all necessary functions for reading in data, displaying surfaces, and making some vital decision. However, file Algorithm.c is empty for you to add your own computations.
