As I just recently learned in a course at my university, the way you
describe it is the standard hardcoded way on older graphics cards. The new
ones (ATI Radeon 9800 and upwards, and I think the NVidias FX and upwards)
come with programmable Vertex and Fragment Shaders, and with fragment
shaders you can script some more elaborate way of interpolation. The guy
showed us some examples of the usual mipmap-fading to avoid jumps between
the different mipmaps, and one which interpolates amongst several
mipmap-levels, depending on the angle of the pixel (and thus the area it
would cover on the image-map). It looked real crisp.

However, we're drifting away from the topic at hand, being of help to tahoma
to get his images look good. :-)
