This is basically mip-mapping, and was described in a 1983 paper: http://dl.acm.org/citation.cfm?id=801126.

I read that Lance Williams invented this technique in 1983, but I remember seeing a documentary on Tron where they had to come up with a technique during the lightcycle race to reduce the Moire effect on the grid and I could have swore that they invented mipmapping to do that, even though it was a year earlier.
