gelmap

[leileilol]

d_polyse.c has this funny dummied out code with a 256 byte lookup table found under a #if 0. If you initialize it and try it, it'll remap the color of the model to a shade initialized by the gel lookup, sort of like an early colormod. Comment out the line before it, and it's an instant blend.

Is it useful for anything? (other than perfectly recreating the same exact lost Quake menu effect unseen in ports and official versions for 11 years since v1.08 came out and took it away)



Makes me wonder what id software was planning with that. Transparent spawns? Blood splatter? (the commented "/* 64 */" suggests that)

maybe it was used for item_deathball

Yeah, there's some really cool things you can do with software Quake that GLQuake just isn't in the same league of; at least without pixel shaders (you actually can't accurately replicate software Quake's renderer in any hardware API without pixel shaders.....)

Actually the PSP has a nifty 32-bit index weird thingie in it's API that let's you achieve black-and-white/nightvision/other colormod effects with some obscure commands. I don't know much about it but I do know that some rendering libs for the PSP make use of it.

Would be a good way to indicate invisibility, along with some wooshy sound effect. Or maybe I watched LOTR too many times.

And green for enviro suit etc. etc. Might be easier on the eye than the hazy-green effect.

This blue tint would be a good visual effect for "quad damage vision".

I'm going to implement lit sprites, so this shouldn't be a problem for them.

But yeah, water and skies can be tricky. One alternative is to recalculate the color blending maps so they include the color shifting, but this won't work for opaque and stippled liquids/skies.

For the opaque/stippled ones, the best way is probably to create separated drawing functions that uses the colormap, so the engine can switch to those functions when the tinting effect is active.

[edit] Actually, the HUD would require some alternate drawing functions too.
