1. A method comprising:
receiving a target shape;
initializing a gradient mesh to a vector graphic having at least one node;
performing a constrained optimization of the vector graphic based on the target shape;
generating a stress metric based on a comparison of the constrained optimization and the target shape;
determining one or more unconstrained candidate vector graphics based on the stress metric;
selecting an improved vector graphic from the one or more unconstrained candidate vector graphics;
mapping the vector graphic to the improved vector graphic; and
optimizing the improved vector graphic based on the target shape.
