• using glDrawPixels
• using texture mapping
• using GLSL.

If you form a pair, you must specify the ``division of labor'' (e.g., who did what) in your assignment TEAM file.

• Use a high-level windowing toolkit (e.g., Qt to open a graphics window and provide user interaction (Xlib and glut ARE NOT high-level GUIs and should be avoided---if you choose either of these, you will have to implement your own buttons, file browsers, etc. otherwise points will be deducted).
• The program should read PPM images.
• Set up buttons and callbacks for toggling/setting various user-controlled options as well as file I/O.
• Implement display of the image in color and greyscale (this should be a simple toggle mechanism, e.g., as a View menu checkbox).
• Implement color image display in both NTSC RGB and Apple RGB color spaces (this will require transformation of the image RGB into CIE XYZ tristimulus values and then transformation back to image RGB for display. See Bruce Lindbloom's color page for various transformation matrices.

• Minimize the use of keyboard inputs.
• Points will be deducted for: "klunky" interface, incorrect image display, lack of color/greyscale conversion utilities.
• You might need to use these support files: glarb.h textfile.h textfile.cpp
• Update: The textfile reading examples in the previous bullet used OpenGL calls pre-version 2.0. I've updated them to use v2.0 calls: textfile.h textfile.cpp. You no longer need the glarb.h file (provided you have OpenGL 2.0 or higher drivers installed as we do on the FX net).
• You will definitely need to use these GLSL files: vert.glsl frag.glsl
