Patent number: 11210838Abstract: Various approaches described herein improve the quality of results when fusing depth maps to generate dynamic three-dimensional (“3D”) models, applying texture details to dynamic 3D models, or rendering views of textured, dynamic 3D models. For example, when fusing depth maps to generate a dynamic 3D model, a fusion component can also incorporate intrinsic color values for points of the dynamic 3D model, potentially making the dynamic 3D model more accurate, especially for areas in which depth values are not reliable or not available. As another example, when applying texture details, a rendering component can apply smoothed, viewpoint-dependent texture weights to texture values from different texture maps, which can reduce blurring and avoid the introduction of noticeable seams. As another example, a rendering component can apply special effects indicated by metadata to rendered views, thereby allowing a content provider to assert artistic control over presentation.Type: GrantFiled: November 1, 2019Date of Patent: December 28, 2021Assignee: Microsoft Technology Licensing, LLCInventors: Ruofei Du, Benjamin F.
