Don't forget to install GLUT package if you are using Linux / MAC / SGI. While using Win32 environment, please download glut32.dll and put it at c:\windows\system32\ . If you want to compile the source codes on Win32 environment using Visual Studio (ex. ver. 2005), please put glut.h and glut32.lib to c:\program files\microsoft visual studio 8\vc\platformsdk\include\gl and c:\program files\microsoft visual studio 8\vc\platformsdk\lib, respectively.

Homework

1. Build a program with a friendly GUI using OpenGL (also GLUT and GLUI or FLTK).
   Please use C/C++ as the programming language.
   Request functions: create a window, add menu control
   Bonus functions: good GUI
   deadline = 10/22
2. Build a program for showing one or two primitives, like sphere or cube, in wireframe mode.
   Use the program of homework #1 as the base.
   Request functions: 3D transformations (translation, rotation, scaling) and projections (parallel, perspective) by mouse and keyboard, change background and wireframe colors, double-buffer
   Bonus functions: virtual trackball, clipping plane, visible-surface determination (back-face culling)
   deadline = 11/12
3. Build a program for showing one or two primitives in shading mode.
   Use the program of homework #2 as the base.
   Request functions: multiple light sources (at least 2), shading (flat, Gouraud), depth-buffer
   Bonus functions: shadows, transparency
   deadline = 11/23
