Psionic Vision

[jim]

I would like to know if it's possible to have this kind of effects in DarkPlaces, without needing to create areas with lots of light and shadow volume passes, which consume lots of computer horsepower:





Because the effects in these images look just what I want to have in some psionic vision mode, which is a fancy name for night vision mode with possibility to see living objects emit light.

I've noticed there's the colormod that I can use to change the texture colour/brightness into some "astral bright" values... I would also like to have a bit of that effect on everything, but to a limited degree. Then add some special volumetric light models to living objects and the psionic vision is ready.

So is it possible to do something to level textures or just have some filter/shader in the view effecting everything?

If I attach some plane model to player's view and put some colour into it and set it to some additive/fullbright/transparent, could that do what I want?

But that wouldn't work with chasecam activated or when player change fov so much the model isn't visible anymore..
