CMPT 370 Spring 2009 Lab3 (30 pts): Animated 3D Model

• Animated means the geometry should change/morph/grow on its own without user interaction, so that you can, e.g., rotate the view while the object animates.
  Hint: timer callbacks. add_timeout(), Erco's FLTK Cheat Page (animated lines).
• Procedurally-generated means an algorithm computes/generates the geometry (rather than just being static or read in from a file). The algorithm should take one or more parameters which can change over time to create the animation.
• Provide a way for the user to rotate and pan the view. You may use the code in CubeView or provide your own user interface to do this. You may find the FLTK OpenGL docs useful.
• Some ideas: swinging pendulum, animated generation of a 3D Sierpinski gasket or other fractal, ant on a Möbius strip, etc. Be creative, have fun!
• Feel free to add on fancier options, user interface, etc.!
• Extra credit (up to 5pts): add interactive picking of objects (clicking on an object to select it or fire some other callback).
