If I enable any type of filtering, textures are smoothed very much even if I stand in front of the block and it fits the whole game window.

That's the purpose of texture filtering - smoothen textures.

This is intended, it is supposed to be used with high-resolution textures (64² at least, 128² recommended).

What for? Just shoothing the texture is not related to filtering at all.

Texture filtering is texture smoothing. Look at other games.

Try using mip-mapping and nothing else.

I began this discussion exactly because I saw filtering in other games, particularly minecraft that has the same resolution textures. There is filtering there and no smoothing (at least it is not visible).
I use mipmapping already and it does not provide far textures filtering. If you enable all viewing range, you see great texture noise.

Minecraft only uses mipmapping, unless you are running optifine or something such.

I have a feeling that you don't know what you're talking about.

Mipmapping is not related to filtering at all. It is just a method to use different textures for different resolution and object sizes.

As someone who has reverse engineered a large portion of the minecraft core, yes, I do know what I am talking about.

Granted, I've been out of it since 1.5 (not the horse update, beta), but I know as of then at least there was zilch anisotropic filtering. Maybe it uses Trilinear, in the backend, but a quick glance at it now shows no signs of settings for anisotropic anyways.

you are correct mipmapping is not related to texture filtering from a technical standpoint (though mipmapping DOES reduce aliasing artifacts). I'm just pointing out minecraft has very little graphics functions in it's backend. What it does have is some decently made texture packs that work around this rather well.

You can FORCE AF and AA in minecraft via either mods or some graphics drivers, but that's all I'm aware of.

This is Minetest though. We don't have optifine.

EDIT: I misread. I apologise. Should always notice Minecraft over Minetest
