I have just finished writing a program that once given end points, it will 
draw lines in 3D space.  Here's my real problem.  I don't know of a fast way 
to determine when walls are hidden or not.  Also, what kind of data structure 
should I use to hold thousands of points that will be in the world.  I am 
interested in having a 3D environment like that in the game COLONY.  Could 
someone please help???!!!

Also if anyone has any "C" code pertaining to this it would be greatly
   appreciated.
