In Response To: Re: Jason Jones interview (M-Class)

Q. In other words, you're trying to figure out if there are objects in the way. You don't worry about drawing the rest of the wall, because there's something in front of it you have to worry about drawing first.

A. The problem is dealt with this way: Given an entire map of the area, the first thing you do is trivially discard all the stuff that is behind you and to the sides of you. Then, for stuff that you can see, you have to figure out what order you have to draw each object. You need to know where it is, what orientation it's in for proper texture mapping, and then whether there are any objects in front of it, such as monsters or missles. So, a very large part of the renderer is devoted to simply generating a list of 3-D polygons with enough information for texture mapping.

Q. I've seen the Preferences section of Marathon where you can turn the texture mapping of the floors and ceilings off. Is that to enhance playability on a slower system?

A. You can turn off the ceilings and floors. Right. we have two totally different subroutines: One of them handles floor and ceilings, and the other handles the walls. The technique and texture maps are totally different.
