Relighting Fragments for Insertion into Content

摘要

A fragment is relit for insertion into a target scene of an image by obtaining a fragment model for the fragment. A set of detail maps for the fragment model are generated, each of which encodes fine-scale shading effects from the surface detail of the fragment. A target scene model is obtained for the target scene, and the fragment model is inserted into the target scene model. The target scene model with inserted fragment model is rendered, and a composited target scene is generated. A modified target scene is generated by combining the composited target scene and the set of detail maps. Weights assigned to the different detail maps can be changed by the user, allowing the modified target scene to be readily altered without re-rendering the target scene model with the inserted fragment model.

1. A method comprising:
obtaining a fragment model for a fragment; obtaining a target scene model for a target scene; generating, based on the fragment model, a set of multiple detail maps for the fragment; inserting the fragment model into the target scene model; rendering the target scene model with the inserted fragment model to generate a rendered scene; generating a composited target scene; and generating a modified target scene by combining the composited target scene and the set of multiple detail maps.
