NewDualContouringDefault uses somewhat safe defaults that sacrifice performance, you may reduce max steps and fix other parameters if facing errors.

NewDualContouringV1 see DualContouringV1.

NewDualContouringV2 see DualContouringV2 and its fields.

DualContouringV1 renders using dual contouring (octree sampling, sharp edges!, automatic simplification).
