"Interactive Texture mapping", J. Maillot, H. Yahia and A. Verroust, Proceedings of Siggraph '93. This was one of the first papers to use the concept of an atlas, or collection of parameterizations. They "cut up" the mesh into regions based on curvature. Each of these regions was flattened out using an optimization procedure, with a parameter that trades distortion for non-flipping.
