  Projects:
  • Ray tracing (due: 2/4/2007) send your code to cs3451@cc.gatech.edu
    • Description
    • Sample input files
    • Code that opens a window and draws a color pattern
    • Code that opens an input file, breaks it up into tokens (run it for one of the input files)
  • OpenGL-like line drawing system (due: 2/25/2007) send your code to cs3451@cc.gatech.edu
    • Description
    • Sample input files
    • Other remarks:
      • Use 512x512 window for drawing your image
  • OpenGL 3D viewer (due (NEW, BETTER DEADLINE!): 3/29/2007) send your code to cs3451@cc.gatech.edu
    • Description
    • Trackball notes
    • Sample input files
    • Sample OpenGL code
    • OpenGL man pages
  • Voronoi diagrams with graphics hardware (due: 4/15/2007, 11:59:59PM)
    • Description
      
    • A short writeup on modeling cones in OpenGL
    • This project was inspired by this work
    • Make your code work for square binary PPM images (sometimes called PPMB images too!) with no comment lines, like this one.
  • Two textures (due: 4/29/2007, 11:59:59PM, HARD DEADLINE, NO LATE SUBMISSIONS ACCEPTED)
    • Description
    • Textures to be used in this project
    • A few links that could help you build a doughnut (call it a torus if you want to impress) model: 1, 2, there is even a code sample for drawing a torus here
