- I am attempting to generate displays of rotated, projected grid surfaces with
- both hidden line and hidden surface elimination.
-
- I have looked at two algorithms:
- 1) "Hidden Line Elimination in Projected Grid Surfaces" by D.P. Anderson (1982)
- 2) "Visibility Determination in Projected Grid Surfaces" by S.C. Wang (1990)
-
- With respect to (1): Is there any implementation of the algorithm on the net or
- are there any hints available as to how to handle the special cases ?
-
- With respect to (2): The algorithm looks great for line drawings but how do you
- generate surfaces with it ?
-
- Please Email replys to philip@klg.com or phil@eyepoint.com or to me
- and I will see that phil gets them.(Phil does not yet have a news feed and
- I seldom reed c.g)
