Begining of 3D floors [continue needed]

[kgsws-CZ]

Well, it is possible. Take this as proof of concept
I made many experiments (begining with translucent 3D water) and i have nearly working rendering part of 3D floors.
Yes, only rendering part - that means, renderer can create all needed fake planes and fake sides.
Problem is with sorting, new fake 3D rendering needs new sorting algorithm that will count with fake planes, fake lines, middle textures and sprites - and i have no idea about this algorithm.

I don't spend so much time on this, so releasing what i have working can allow more people work on it.

What is (semi)working?
- fake planes (flats) computing
- fake midtextures (3D floor sides) rendering
- real-time transfer light on real walls

Any problems/what needs to be done ?
- missing sorting algorithm
- fake planes does not appear when skybox is visible
- fake midtextures are not translucent
- fake midtextures don't count with backsector fake floors (= walls in water!)
- slopes are problematic, it does not matter if you have sloped fake floor, or normal sloped floor touching fake floor.
- transfer light does not color sprites correctly (i were not working on sprite coloring)

So, i hope someone will be able to continue, or finish this work. Would not be 3D floors in ZDoom's software renderer cool?
Dev info: diff file created on revision 2296 (yes, its little older), i hope all my changes are marked with // kg3D

For anyone who don't want to (or can't) patch/compile i can provide only screenshots from random progress (i am running on linux):

More screenshots here.

Most screenshots are taken from few 3D floor supporting mods, in few of them you must "set vid_renderer 1" to play

Ummmmmmm......

Awesome.

Holy-

That's revolutionary.

I'd build you guys an EXE but I still haven't gotten my build setup working on my new drive.

I guess this is good motivation to go ahead and do so.

Moved to code submissions.

Honestly if it's not too messy, I would like to see this committed as is. Something is better than nothing.

What about physics and collision? Are the floors interactive or are they just purely cosmetic?

[Blzut3]

Graf added the collision code to ZDoom a long time ago IIRC. I don't think it was ever enabled though.

Edit: I just tried the code. It seems to work reasonably well. Even without proper sprite sorting it does allow some GZDoom mods to be playable under ZDoom. Seems to work really well if you are looking at a 3D floor from below.

[Xaser]

Correct. There was some talk a while back on whether or not to enable the code, but nothing ever came of it. It's there somewhere, though.

[NeuralStunner]

I figured he would have at least left it active... You wouldn't be able to see them, but they'd still "be there".

[Graf Zahl]

I've created a new branch where I merged this in. It's not yet ready for inclusion in the trunk, I think, but it should definitely be kept in a state where it can be worked on.

[Dark-Assassin]

I just exploded.

[Graf Zahl]

I just checked Nimrod with this.

Not bad for a start. It sure is still glitchy as hell and definitely needs some work but it looks very promising.

Awesome.
