1. A method for converting an adaptively sampled distance field of a graphics model to a triangle model, the adaptively sampled distance field including a plurality of surface cells storing distance values having corresponding gradients, comprising: assigning a vertex to a center location of each surface cell; connecting the vertices of neighboring surface cells to form triangles while satisfying a predetermined constraint; and moving each vertex, in a single step, to a new location according to the distance value and corresponding gradient of the vertex to substantially conform the triangles to a surface of the model.
