Better yet, how many have working scene rendering code?  Doing bitmapped walls
Wolf-style isn't too tough, and it can be done with either massive lookup
tables or a couple of multiplies per column of pixels.  The tricky part is
doing textured floors and ceilings, since you have to effectively perform
a Bresenham or similar line draw across each tile on the floor. (ick)

It can also get messy figuring out how to draw the objects and beasties.

I've opted (for now) to not use textured floors and ceilings since I'll be
needing a good chunk of processor for the AI routines.

Could someone who has seen Ultima Underworld (and others?) give
a quick eval?  It would be good to see:

- #angles you can turn to (4, 16, >500, etc)
- #degrees in field of view
- what surfaces are textured
- frames per second for a specific machine
- vertical movement resolution

For Wolf, the numbers are approximately the following:

- Over 640 angles (320 angles, and under 180 degree field of view)
- Roughly 135 degree field of view (I don't have it in front of me)
- Walls textured, floor all one color, ceiling all one color.
- 386/33 gets about 15-20 fps for me at full size.  I've seen it run at
  or over 30 fps on a 486.  It can run on a 286, but is a dog at full size.
  (full size means 320 x 100 window)
- No vertical movement.
