I need to get that card working again so I can try framegrabbing it on some key points... though I really wonder just what the limit to shader languages and the pipeline itself really is.

Being able to have dithering like that again on 16-bbp games would be just simply amazing. I hate this banding crap the GPU vendors did.

You say that like it's a bad thing. 🤣

What game is that screenshot from, the one under Quake 3 (with the buggy waiting at the traffic lights), please? I don't recognise it.

Saints Row The Third.

Thanks. I assumed it was a much older game, what with this topic being about 3DFX (I'm not well up on PC graphics cards!). I do have Saint's Row 3 (I bought the GOTY edition a while back), but haven't played it past the first few missions (I remember you couldn't go into first person view when driving (I have the XBox 360 version), you always see your car on-screen, unlike in the GTA 3 onwards games, is the PC version of SR3 the same?).

I'll have to give SR3 a proper go, and also go back to GTA V (a fantastic game*), I'd gotten quite far in the single player mode, then for some reason got distracted. I never played the multiplayer (I'm not a fan of online multiplayer), but the single player is great. Much better than GTA IV (I never liked that at all), and nearly as good as San Andreas (my all time favourite GTA style game). The Saboteur was another great GTA type game, and also Scarface, and Mafia (I've not played Mafia 2).

I thought about using the Quake III Team Arena menu system to do something (for myself) - video test pages. Why didn't I think of this earlier?

This page should expose the filtering with the 50% dither pattern.

1 layer, 2 layers, 4 layers, 8 layers. Progressively they should be able to expose the dither pattern of the Voodoo more.

also it's her again 🤣

Not released yet as I didn't make many pages, and it currently only is accessed in a linear fashion (no menu yet)

Stuff I still need to do:
- Alpha blend page with overdraw and modulation test (which Rage will fail)
- Modulated blend page w/ detail texture samples (which Riva128 will fail)
- Rectangle textures (which Riva128 will fail)
- Texture switching test (a single model with like as many different surfaces as possible being spun)
- Large 30fps 512x512 video test (which Voodoo will fail)
- Even more filter tests to research the filter

Benchmarking and game probably won't work...

What is "Old style" mean? It certainly does look like shit... but what is the algorithm in use here?

Also I want her hat.

The old method of having a inverted normal shell of black and an environment map blended on as popularized by Jet Grind Radio in 2000, as opposed to some newer cubemap, lighting or edge detection shader-based methods.

BUMP, I am porting this to GLSL!

Pass1: leifx_dither
Pass2: leifx_gamma
Pass3: leifx_filter
Pass4: leifx_filter
Pass5: leifx_filter
Pass6: leifx_filter

Good news: It's still six passes.
Bad news: It's not written for an injector so you can't easily try it for everything. also, the dither and filtering sucks, so this is considered preliminary at the moment.

Also I still wish I had interest and help from other shader programmers. I've only posted this shader in a few places and only got posts as good as 'cool'. I don't consider any praising sugar posts to be progress.

I'm kinda amazed and I'm not even sure what you did, but the things you do are kinda out of my reach anyway. You must be veeery intelligent.

I tried programming and I frankly suck at it (I make too many silly mistakes and loose track of what I'm doing constantly. Modding is as far as I can go).

I think your talents for programming are "somewhat" out of our league 😊

Updated the screenshot since I just simply direclty ported my filter code from the other version with better results 😀

Still lost on dithering.

Leileilol,

What do you do for a living, if you don't mind me asking? You certainly have a very diverse skill set.

Out of curiosity, how trivial/non-trivial would it be to convert it to a .fx for use with Dosbox? Or is that simply beyond what .fx allows you to do?

I've actually did try that a page back with poor results since this multipass shader doesn't work as well when it's one. The 4x1 filter is linear and needs to be applied four times.

Lei-lei, do you think it could also be possible to recreate Voodoo1/2's fake trilinear filtering AKA Enable mipmap dithering AKA dem mipmap transitions with the use of a filter shader too? (Ignorant question)

You have probably seen it before, this is what it looks like:

Fake trilinear is possible if it wasn't a postprocess shader but a shader applied to every triangle. Thsi proves it's possible to select different mips and the fake trilinear can be done via some sort of dither table between them. Somehow.

However since this is a post-process shader thread, it's not something I can do in that 🙁

🙁 If you ever feel adventurous enough to experiment with that, I look forward to see the results.

Ah, okay, my bad; I overlooked the significance of what you were saying there.

Just wanted to pop in and say that this is awesome work.

Here's a version with a preset for RetroArch.
