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.

摘要翻译： 通过获取片段的片段模型，片段可用于插入到图像的目标场景中。 生成片段模型的一组细节图，每一个都从片段的表面细节编码精细的阴影效果。 为目标场景获得目标场景模型，并将片段模型插入到目标场景模型中。 渲染具有插入片段模型的目标场景模型，并生成合成目标场景。 通过组合目标场景和一组细节图生成修改后的目标场景。 分配给不同细节图的权重可以由用户改变，允许修改的目标场景容易地改变，而不用所插入的片段模型重新渲染目标场景模型。
