Hey guys. I have a silly question. I've looked thru entire LLVMPipe documentation and I wonder if it is possible to disable texture filtering and perspective correct texture mapping.
<Seacat17>
Is it possible?
<MrCooper>
setting GL_TEXTURE_MIN/MAX_FILTER to GL_NEAREST should disable filtering

<Seacat17>
Okay... What about perspective correction?
<Seacat17>
I want to mess with some older games I love.
<Seacat17>
That do not have software rendering or good modding support but I want to try and bring PSX vibes to them.
<pendingchaos>
I think LP_PERF=no_mipmap,no_linear environment variable should disable filtering
<Seacat17>
Testing these. They prevent games from launching.

Rebooted my PC for good
<Seacat17>
for good measure*
<Seacat17>
And logged in with X11. Could you please resend these commands? My dumbbutt forgot to copy+paste them.
<Seacat17>
Nevermind they're saved in buffer history

Performing more tests. Still, is there any way to disable perspective correct texture mapping?
haaninjo has joined #dri-devel
<Seacat17>
Basically can I enable affine texture mapping?
<Seacat17>
Testing Godot's OpenGL mode, env vars above do indeed disable texture filtering for all the materials.
<K900>
Seacat17: Doubt it
<K900>
At least without actually patching the driver
<Seacat17>
Dang it...

And I'm not a programmer so I doubt I will be able to patch it myself.

But also just disabling perspective correction won't give you the PSX look you're looking for
<K900>
There's more very specific weirdness to the PSX
<K900>
That is definitely not something you can recreate with a setting
<K900>
You probably need to inject some custom shaders
<Seacat17>
I know, I'm just trying to get as close as I can without modding the games.
