Crazy.

It is useful, if your texture is large compared to your image (in pixels) to prevent aliasing. You probably will not need it, if you are using a large rendersize and a lot of antialiasing samples. These however usually cost more time than a little texture filtering would. The difference is most noticable when the texture shows great contrast. In the attached image, the floor has filtering, the wall not. As one can see, the farther the distance, the smaller the patterns become, and therefore the greater the texture (512 pixels) is in relation to the image, so it can look unpleasing (nevertheless interesting) when the aliasing artifacts show up.

 

wow, this is an awesome demo.  Thanks! 

seeing before and after effects is a big help to learn this stuff.
