Texture Filtering

I'm just adding in the ability to set texture filtering to my in-game options panel, and I wanted to make sure I have all the necessary options available. I have bilinear, trilinear, and 2,4, 8 and 16 sample anisotropic filtering. Does that cover pretty much any modern video card?

I see also options for "flat cubic" and "gaussian cubic" but I've never seen those in a game context, so I don't see any reason to include them, unless anyone knows otherwise. I figured they're probably legacy crap from DX8 or something, before anisotropic became so popular.

I have never seen them in the options of any game.

Your list covers any anisotropic setting. To my knowledge, gaussian cubic is a filtering technique supported in DX8. Usually a video card which supports cubic magnification supports anisotropic magnification as well, so I suppose this is one of the reasons it hasn't been implemented in videogames.


Most 3D games have an advanced video panel with such options (mainly non-casual games of course, such as Half Life 2).

With flat cubic and gaussian cubic?

I jolly badger, on a skateboard, think not.

Whoops... I thought you were referring to the filtering options. :)

Ok, thanks guys, looks like I have all the important options covered. I never realized until today just how much of a difference there is between trilinear and 2x anisotropic.
