Hi, dingo.

I have never even tried to edit a Doom level, I'm sure in some ways it must be easier but then you have a lot of constraints on your level designs because any (x,y) position in the level can only have one floor height and one ceiling height so you can't, for example, have a bridge running over the top of an open area. Quake I enjoyed mapping for but we really didn't play it once Quake 2 came along.

Something, something, convex hulls :) I do remember being told once that in 3D graphics everything is triangles and that you could only see the ones where the points go clockwise. I dunno if that's still the case but it seemed to be in the Quake era.

I dug out the editing tools a while ago, I could probably get the BSP editor to run again if I really tried and I'd be really interested to see what kind of speed I could get running qrad on an M1 Mac - I am sure the build tools had source available? I know my main PC from the time is gone (not that I remember disposing of it) but I did do some build on a Windows 2000 laptop which I still have. It no longer powers up, probably an IC gone on it which could be repaired - one for the never-never list!
