5. 5 OpenGL/GLU/GLUT/GLUI OpenGL v1.4 (latest) is the “ core ” library that is platform independent GLUT v3.6 or v3.7 (beta) is an auxiliary library that handles window creation, OS system calls (mouse buttons, movement, keyboard, etc), callbacks. GLU is an auxiliary library that handles a variety of graphics accessory functions GLUI v1.0 or v2.0 (beta)is a GUI manager written by Paul Rademacher (rademach@cs.unc.edu).

15. 168 471 Computer Graphics, KKU. Lecture 1015 Double Buffer Graphics card scans out the image on the frame buffer. What rate is this done at? So what is the problem with this? You might be in the middle of drawing a frame when it decides to scan out the image What is a solution? Have two separate frame buffers, one that the card scans out of, and the other you draw into. When you are done drawing a frame, you switch their roles What are the memory requirements?
