Abstract
Methods and systems for material refinement for portions of a three-dimensional (3D) object data model are provided. An example method may include rendering a portion of a 3D object data model, and determining a first appearance metric between an appearance of the portion in the rendered view and a two-dimensional (2D) image. For one or more iterations, a modification to material properties associated with the portion may be determined based on the first appearance metric, and another view of the portion of the 3D object data model may be rendered. Also for the one or more iterations, another appearance metric between and an appearance of the portion in the rendered another view and the 2D image may be determined. Additionally, modified material properties for the portion that are associated with a minimum appearance metric of the one or more iterations may be stored for the 3D object data model.
