Hi!
I would like to draw a rectangle on the screen that will delete everything inside. For example if I draw a red square on my screen and then draw a smaller rectangle inside, it will cut it and appears like the rest of the screen. I use the GLUT library. Any help would be appreciated.
Thanks!

You should be able to do what you want with the stencil buffer. Basic steps would be
- Draw your small rectangle to the stencil buffer
- Enable the propery stencil test and draw your big rectangle.
