Abstract: Techniques are disclosed for generating and using a conformal or UV mapping between an object's 3D representation (e.g., a polygonal mesh model) and a corresponding 2D representation (e.g., texture memory). More particularly, techniques disclosed herein generate a conformal mapping that allows the rapid identification of disparate locations in texture memory (e.g., those that span a seam) that are spatially similar at the corresponding 3D locations. The ability to perform 2D-to-3D-to-2D mappings quickly, grants the ability to filter across a conformal map's seams—an action that has previously been avoided due to its high computational cost.

Abstract translation: 公开了用于生成和使用对象的3D表示（例如，多边形网格模型）和对应的2D表示（例如，纹理存储器）之间的共形或UV映射的技术。 更具体地，本文公开的技术生成保形映射，其允许快速识别在相应3D位置处在空间上类似的纹理存储器（例如，穿过接缝的纹理存储器）中的不同位置。 快速执行2D到3D映射的能力，允许过滤整个映射图的接缝，这是由于其高计算成本而先前避免的一个动作。
