1. A processor comprising:
one or more circuits to:
compute, based at least on an input representation of an object, a signed distance field (SDF) at an initial grid resolution of a grid;
subdivide and deform the grid to generate an updated grid at an updated resolution;
compute an updated SDF using the SDF and the updated grid;
generate a triangular mesh using the updated SDF; and
subdivide the triangular mesh to generate a parametric surface representation of the object.
