• Comments in each file describing the purpose of each source file and your name.
• Print a help message if "h" is pushed.
• Use GLUT_RGB mode and be double buffered (GLUT_DOUBLE) with some sort of interactive or automatic animation, just like your previous programs
• At least some user interaction, in the form of keyboard commands or mouse control.
• Have at least four independent objects either composed of other basic shapes (i.e. cubes, cones, cylinders, etc.) or from defined polygons. This is a little hard to measure so we will check each proposal to see if it fits our general idea.
• At least one instance of a dependent OpenGL transformation which is at least two levels deep (i.e. there are at least two glPushMatrix() / glPopMatrix() calls) excluding any that you might have for your viewing transformation.
• use the following OpenGL features:
  • glLight
  • glMaterial
  • texture mapping, especially MIPmapping, GL_MODULATE texture environment

We want to see you reach a little beyond what we have taught you. We're looking for creativity and some understanding of why things work the way they do.

Here are a handful of fun things you might use to get more points or extra credit, but these are not the only tools at your disposal. We may not have talked about these much but they are an important part of OpenGL. (Don't worry, they won't be on the exam if they weren't in the notes.)

• Use linear glTexGen to "project" texture maps onto objects
• Use spheremap glTexGen to make objects look reflective
• Use clipping planes to cut off portions of an object.
• Use GL_LINES or GL_POINTS as well as polygons.
• Use blending (GL_BLEND) to draw transparent objects (this one's tough to get right).
• Many others...

• Correct use of glEnable and glDisable.
• Vectors used in glRotate and gluLookat-up-vector are normalized (length of 1.0).
• Things you turn on, like GL_SPECULAR, GL_LIGHT0 through GL_LIGHT1, are actually used.
• And others.

These requirements may be traded somewhat depending on the content of your project, but we expect the overall difficulty level to remain about the same. For example, you might not use much texture mapping if you were to use complicated transformations, but we expect you to explain that in your proposal.

Here are some suggestions, but these are not the only ideas you can propose. One thing that might help you is to think about your personal interests while you try to come up with a proposal.

• park demo
  • walk through a park
  • trees made of cones and cylinders
  • some signs posted that say "stay off grass" (textured)
  • afternoon sunlight (directional light off-center)


• clock
  • textured clock face
  • moving arms
  • point light near top of face so base is darker


• flying game
  • mountains
  • buildings with texture
  • sunlight


• data animator
  • read text description of
    • locations of cubes, spheres, and cylinders
    • relative motions
  • draw objects moving, allow keyboard to move camera
