Quake with unfiltered textures looks great, if you play it in the originally intended resolutions. In 1996, 640*480 was the highest resolution that achieved playable framerates in most high-end machines.

I used to play it at 512*384 in a Cyrix MII-300 in the early 2000s. Had a solid 12 fps which was surprisingly enjoyable, and looked pretty good to me.

Nowadays, its texel-to-pixel ratio at the highest playable resolutions is poor. 

We don't need filtering, just higher texel density. Love my crisp edges!

I wouldn't mind seeing a coop episode in AD. Something that detects coop and requires two people to progress if coop is on. E.g. two pressure plates require both players on them to open a door...one player stand on a pressure plate while another shoots an exposed button juuust out of view of the player on the pressure plate. You could use the dual pressure plate idea to split players up across two sides of a room, Portal 2 style, and have them fighting and helping by shooting across the gap. 

Unfiltered Quake looks fantastic.

Aside from the sharper edges on things, textures just pop with detail compared to the filtered versions.

More than just fullbrights and overbrights was lost in the initial SQUEEEEEEE-fest over GLQuake. 

Good filtering is much more important with high resolution images than it is with low res stuff (where it just makes them blurry). 

One thing i like about filtering is that how smooth it looks in motion, in unfiltered mode is the scene is very noisy/sparkly as you move the camera.

However, filtered mode makes each pixel less vibrant/contrasty, everything gets a little bit more gray and colors shift towards the local average. For example that wall texture in e1m6 has lots of little single pixels of green and blue that pop really nicely in gl_nearest, but in gl_linear they are dulled and dim, and blend into more of an average grey. I feel that's one of the main reasons quake world textures look better unfiltered, it's the pixel art precision of some details that get desaturated and dulled in filtered mode. 

Ok, since metl mentioned it, the sparkly pixel movement phenomena is temporal aliasing. I want temporal antialiasing in Quake. 

 

GL_NEAREST_MIPMAP_LINEAR is the best compromise IMO. Sparkles are caused more by not using mipmaps than by using nearest filtering, and linear sampling between miplevels eases miplevel transition artefacts. The other improvement is to use screen-space derivitaves from unwarped texcoords when sampling warped textures, otherwise they shift between miplevels as they warp. One of those things you normally don't notice until it's pointed out to you, then you can't stop noticing it. 

yeah my settings are GL_NEAREST_MIPMAP_LINEAR + anisotropic set to the max. The thing i don't like about mipmapping in hardware rendering is how floors (and other edge-on polygons) blur into a solid color, and anisotropic reduces that problem quite a bit. 

Agreed, anisotropic is essential. Different people are different, so I tend to find anything beyond 4x is not that big a deal, but I won't go below 4x. 

It would be nice if there was a way to detect the edge of a face that also corresponds to the edge of a texture and clamp the texture so that it doesn't bleed the color from the opposite side of the texture over. 

I want to see all of the models from Banjo Kazooie converted to mdl, with all of the animations kept intact. The Quake marine's model should be altered to have a backpack on his back that Kazooie occasionally pops out of. Also, the Quake marine can now double jump, and on the second jump the player can see Kazooie pop out of the backpack and flap her wings. Also, I would like to see a map that completely re-creates Gruntilda's lair and... Ahh f*ck it, I'm just going to go play Banjo Kazooie...

Seriously, I would love to see some kind of volumetric fog implementation similar to what is seen in Quake 3. 

Centerprint with constant cheesey rhymes 

Ranger will end up slobbering,
after the Shambler gives him a clobbering.

And so forth. 

...given how well normal fog can be used.

Also pretty sure the edges of objects have the same definition i.e. a straight fucking line, regardless of what texture mode you're in. Anyway, you're all wrong, I've been playing with GL since it first came out and fuck everything else. 

Just adopt Q3 BSP already if you want stuff like volumetric fog. :) 

Another thing that no current Quake engine does, AFAIK, is gamma-correct mip-mapping: http://filmicworlds.com/blog/gamma-and-mipmapping/ 

As you should know by now, the value 187 is actually half-way between o and 255. 

 

 

Wrong. The problem is that that article was very poorly written. Here's the actual equation for gamma-correct gray:

((255^2,2)÷2)^(1÷2,2)=186,083713

Most of the gamma correction articles on the web are poorly written. 

in terms of photon counts, that's entirely correct.
so if you want correct lighting, then you need a pipeline that is actually aware of srgb (eg: vid_srgb 2 - note that you'll need to reload all the textures too).

using hardware srgb extensions to basically disable srgb (yes, backwards, the extensions are all a pain to read, and with drivers giving the wrong results too) gives you brighter darks and also resists oversaturation much better (which makes rtlights+specular much more tollerable).
but yeah, dark areas being brighter kinda hurts the whole quake ambience, and it draws more attention to how rtlights have sudden cutoffs instead of fading to infinity. I'm sure deathmatch players would love it though.

also reduces banding with eg r_lightmap 1.

and regarding gamma-incorrect mipmapping - textures that get darker with distance is a feature, not a bug! :P
(or use dds files that were generated with a proper tool) 

Er wait the thread said "Realistically" ha ha. Inspiring to see all the ideas people have.

P.S. to Qmaster: Will email you soon (i.e. this month). 

That's interesting. I probably should read up on that.
