Regularization of implicial fields representing objects and models

Abstract

A method regularizes a distance field of a graphics model or object. The distance field includes variable scalar values and a set of fixed zero values. The zero values define a boundary or surface of the object. The distance field is evaluated by a cost function, optimized according predetermined parameters, to determine a cost of the distance field. The variable scalar values are then randomly perturbed while holding the zero values fixed. The evaluating, determining, perturbing steps are repeated until the cost is less than a predetermined threshold. The distance field can be in the form of a non-differentiable implicial field. A surface of the graphics model can be textured or stenciled by following streamlines along the gradients of the regularized distance field.
