Assignment 8

General Information

E-mail C++ source for the program described below to me at ffggc@uaf.edu, using the subject "GA8". (If you wish to discuss the assignment with me via e-mail, use a different subject.)
- If possible, please send your source as an attachment to your e-mail, rather than as part of the body text.
- Send source only! No executables, project/workspace files, etc.
Be sure to include your name in your e-mail.
Due: Tuesday, November 18 (any time).
Worth: 25 points.

See the Homework Policies handout.

Write a C++ program using OpenGL/GLUT that meets the following requirements.

As before, draw a 3-D scene with proper HSR.
Make use of the model/view transformation to place objects, lights, etc., in the scene.
Include proper lighting using the Phong model.
- Allow the user to change the lighting parameters somehow (light properties, material properties, etc.).
- Your program cannot rely entirely on normals generated by GLUT: gluSolidTorus and the like. You must include a glNormal* call (or use an “evaluator”; see “Suggestions for Full Credit”, below).
Your program must provide documentation in either a graphics window or a pop-up menu, as in previous assignments.

As before, but here are some new ideas. (The old ones will still work, assuming they have not been covered in class yet.)

Figure out how to use OpenGL evaluators. Use one. (You can also get the evaluator to generate normals for you!)
Write the lighting yourself, without using OpenGL lighting commands (vecpos.h might help).
Implement smooth vertex-normal generation using the Gouraud-shading technique (a vertex normal is the normalized average of the facet normals of adjacent facets).

Particularly well-done programs may be demonstrated in class.
