CST 99.6.4 Graphics

First Part (rotate the cone)

I'm not sure whether the values are correct. Could someone check against
his/her values?

1) Scale: 4*x, 4*y, 13*z
2) Rotate about y-axis by -13.33 degrees
3) Rotate about x-axis by 22.62 degrees
4) Translage: x -1, y +3, z +7



Last Part:
Clearly the Sutherland algorithm doesn't work with concave clipping poly's.
What to do?
Break it into smaller, convex poly's?
Any other ideas?

Cheers, 

Mo
