Precept 8, On assignment 4

• when subdividing the tetrahedron, just subdivide the four faces: you don't have to subdivide it into more tetrahedra (extra credit if you do, though)
• check out the lecture notes of lecture 9 for a description of the winged edge data structure. Try to figure out which parts of it you need, and which you don't need
• if you'd like pointers to literature about generating trees, clouds, etc., just send me e-mail
• Once you have established the size and location of your "world", you can use the gluLookAt function to set up your camera, and the gluPerspective function to set up a perspective transformation. Let me know if you're having problems with this
