Wonderful! [smile]

Have you figured out how you're going to render the numerous convex floors that Doom sports? I know that this one gave me a lot of trouble in the past when I tried to tesselate these to no avail. :-/

Wow that was fast [smile]

I gave up on them a few days ago(as my journal entries indicate) and started on walls. Of course I expected walls to take a while, but they are quite simple and I'll have to go back to working on floors soon.

I've looked through the DOOM source trying to find how it does it, but the thing's a mess. I also downloaded a few source ports, but they all appear to be simple re-compiles with a different graphics / sound library and didn't provide much help. :(

Very nice, when's the flooring coming in? [wink]

I'd check out some of the DOOM ports that use OpenGL or Direct3D -- they've clearly figured out some method for doing this.

It'll be in when it gets done, just like eveything else.

I found some code that I think is to figure out the segs angles, I'll give floors another go tomorrow.

Software DOOM ports will probably use a flood-fill style algorithm, that doesn't really work for real 3D [sad]

All the 3D hardware accelerated DOOM ports I've come across use glBSP, which is cheating [wink]

With regards to upside-down doors/walls, I had a similar issue, (though more obvious with backface culling) resolved by sorting the floor/ceiling so that the floor is always below the ceiling.
