GLSL?

Post by **Enjay** » Sat Aug 23, 2008 22:44

When checking out r163 I noticed this in the change log

Started work on GLSL renderer - split off the main rendering loop.

I've looked up GLSL on Wikipedia and, other than finding out that it was to do with shaders, I didn't get much more than that - at least not that made too much sense to me. So, I was just interested to find out what the implications of this "GLSL renderer" will be for GZdoom.

Hopefully this means we will have better dynamic lighting (vertex/pixel lighting VS lightmaps).

Or even the software Doom fog emulated correctly!?

(I still dream of the day that GZDoom will correctly light up models... they look so flat and dull without lighting, and I'm forced to bake shadows on to their textures which cost a lot of time on my computer...)

While we're fantasizing, I want accurate collision detection for models.

I won't make any promises - but this will certainly take a while to get even the basics working.

Well, I'm glad you're managing to find time to get back to GZdoom and do stuff that you are interested in with it.

Yeah, just one weekend day with incredibly shitty weather. I would have preferred doing other things...

Take your time Graf... I actually trust that the likeliness of this happening is far more than Doomscript.

I have to confess, I'm still not sure what this will allow. Could the things that Nash mentioned be made possible by this? What sort of other improvements is it likely to allow? Will it mean any additional end user or modder tailorable features?

I really can't say. The one thing I hope to get from it is a lighting mode that's closer to what Doom's software renderer uses.

One thing's for sure: The GLSL renderer will at least require a Geforce 8600 or better

Heh, good thing I upgraded my video card to an 8800 a few months back!

Hmm... time to upgrade!

Heh, yes, that might provide the final shove that I need to upgrade my machine too. I've been toying with doing so for months.

See that Graf? Your hobby is forcing people to buy new computers.

So what if this never takes off?

Sshhhh! My wife might hear you.

I'm happy to have the excuse.

Going to be honest. I know nothing about graphics cards. What good card is out there that is half-~~life 2~~ decent, capable of running GZDoom and other games and reasonably cheap (under 100$)
