It's overall unfinished and probably wont be finished hence posted here and not in projects.
Whoever wants it can steal and use it.

Also it works in software, but would require two different sets of decals (flipy for GZDoom, and without flipy for software).
There's as well something really weird going on with FOV in software.
Also the player's sprite doesn't get rendered for whatever reason, even with enabled chasecam.

Also important thing. I haven't tried, but it might be possible to use cameratexture as a material for a model. At least IIRC models use the same texture subsystem as every other graphic in the game except sprites.
This way you could make the portal round and also put portals on floors/ceilings. I can't verify nor try this because I'm so shit at modelling that I can't even do a simple triangle fan aka oval.
I tried and it DOES NOT work. RIP proper portals.

The song doesn't have a meaningful name where I found it.

This is ...the fuck O_o?!

[wolfboyft]

Very impressive! Now all we need is floor decals

One question: Are the portals calculated realtime?

[ZZYZX]

Yup. But the player's sprite isn't rendered so it isn't noticeable. I blame Graf.

Works fine here using the latest GZDoom devbuild.

Dafuq, don't tell Cutmanmake... didnt he make the portal mapset?

I made a portal mod but it had very little to do with the real Portal... or portals in general (it was more of a teleporter gun). It's also very dated. You would be better off making some new maps instead of using mine.

I remember asking for cameratextures on decals a long long time ago to try and achieve portals like this too but I didn't think it ever came about.

[Graf Zahl]

I blame Graf.

I blame the incredibly bad camera interpolation code which was a complete nightmare to adjust for portals. Have some fun looking at the shit I had to do in there in order to make it work.
Of course this particular problem has been fixed for a few revisions already.

[ZZYZX]

Fixed the portals a bit so that the odd bug at video's 0:58 is gone (player now always gets teleported in the right direction).
Also fixed software in my mod. But not like it looks good there:

---

Both the FOV (which apparently assumes the texture is always square, instead of using actual proportions) and the particle projection are horribly broken in the current dev build of GZ (1814). The player's sprite rendering in OGL indeed got fixed though

In that case, please post a bug report, along with a demo WAD so it can be fixed when I find some time to work on the code. Otherwise it will most likely fall through the cracks.

Too cool! I should be using this for a map I have planned; "Lost in Space"

Kudos!!!!!!!!
