1. A system for modeling a graphics object, comprising: means for providing a model, generation parameters specifying a fixed level-of-detail, and conversion parameters specifying variable levels-of-detail; means for generating an adaptively sampled distance field having the fixed level-of-detail from the model; and means for converting the adaptively sampled distance field from the fixed level-of-detail to the variable levels-of-detail while concurrently generating rendering primitives.
