So many typos and slip-ups it is hard to understand :O
I'll try again:
Yeah I know what it does. Sort of...
Lets say that you have a geometrical figure. A cube, a house made of a several cubes or a horse made up of small cubes and cones, or something like that. Now a geometrical figure doesn't look nice on its own. It needs a texture, to fill in colours, define parts and their combination and stuff. A CS skin or a GP3 livery is a texture. Apply it at the right location on the geometric model and it looks good, the point being the horse eyes does not appear on its butt or left hoof but at the right place in the head. This is called texture mapping.
So, texture mapping is a simple graphical modeling technique that creates complex appearing three-dimensional objects. A nicely shaded texture that is placed on the 3-d model enhances depth perception, clarity and sharpness as well as it makes clear what the object is supposed be and be made of. You can see if the cube is a piece of sugar, a brick, steel or hay.
Anisotropic filtering seeks to achieve the best possible texture mapping in situations where the model
It's only after we've lost everything, that we are free to do anything.
