Compiling & Running Code

All programs use C, OpenGL, GLUT, and GLUI.

For Linux, you can use the provided bash script:

e.g. for program: triangle.c

./run triangle

for Windows (using Cygwin), you can use the following commands

gcc -o FILE.exe FILE.c -lgl -lglu -lglut -lopengl32 startx (gives you xterm window) ./FILE.exe

for Mac, you can use the following commands

gcc -o FILE FILE.c -framework GLUT -framework OpenGL ./FILE
