Ah, so you do viewportal blending aswell. Nice.
Yesterday, after trying your demo i searched the web for Portal/view blending. Someone did it with a depthmap, but your color approach seems much "simpler".

You mentioned a HDR pipeline. What/How does it help in this case?

Idea: For your portal, i had an idea yesterday. For moving objects through. I thought, by deforming the collision shape of an object with stands on a floor portal for example, it should move thorugh the Portal(visually, a clone does the same on the other side).

HELP, iam thinking in portals grin

PS: For the stuttering: stay in front of the box, look directly into it(but stand in front and not in it). Now strafe left/right. rotate the cam a bit if desired. And when passing the corners(from your mainview perspective), it seems to stutter, while you're in the same room.

EDIT: So the stuttering doesnt appear when walking through the protal, but in the startroom.

Wow! Great effect!
You can do some real nice levels with this. I once played a UT2004 map and wondered upon the really huge size it seemed to have, but it was relatively small and just got portals like these at the gates and always lead back into itself.

It helps really much. without HDRR colors brighter than 1 or darker than 0 will be 'cut off'

If I use something like RGB 0.5, 0.5, 0.5 it would work, too - even without HDRR.
But it can happen that a normal entity has exactly this color.

but (normally) an entity will never get a color like -1.0, 0, 0

Ok, but how do you implement those negative color channels?

@Kartoffel: It doesn´t really work for me. It seems to run really slow and moving the mouse just very little makes me look somwhere completely different, same for the movement.

@Slin have you got a program like fraps which can show you the current fps?
I didn't included default.c sorry...

I sometimes had the problem that everything ran with constant 30 fps when using shaders.

But I can't change it anyway because I haven't got the source code anymore.

EDIT: @Rackscha
I'm rendering into a 4x16bit floating point texture (format: 12222)

What?. shocked
It runs with stable 60 fps (limited to 60) on my ATI HD 7850...

A lot of shaders are active (18) but your graphics card should be able to handle this...

EDIT: programs like fraps make applications run slower, but 2-4fps is still wayy to slow.
