Various implementations disclosed herein generate a mesh representing the surfaces in a physical environment. The mesh is generated using multi-resolution voxels based on detected depth information, e.g., from a depth camera. The techniques may use multiple hash tables to store the multi-resolution voxel data. For example, the hash tables may store each voxel's 3D position and a truncated signed distance field (TSDF) value corresponding to each voxels' distance to a nearest surface. Each of the multiple hash tables may include data corresponding to a different level of resolution and those resolutions may depend upon distance/noise or other factors. For example, voxels close to a depth camera may have a finer resolution and smaller size compared to voxels that are further from the depth camera. Techniques disclosed herein may involve using a meshing algorithm that combines multi-resolution voxel information stored in multiple hash tables to generate a single mesh.

Multi-resolution voxel meshing

In one implementation, a method includes: obtaining locality data characterizing objects and relative spatial information of a volumetric region around a user; synthesizing a mesh map of the volumetric region based on the locality data; selecting synthesized reality (SR) content based on the mesh map, wherein the SR content satisfies a dimensional variance threshold relative to one or more portions of the mesh map; compositing at least a portion of the SR content with the mesh map in order to generate composite SR content; and presenting the composite SR content to the user in order to occlude at least a portion of a visual presentation of the volumetric region. In some implementations, the SR content is adapted to fit the one or more portions of the mesh map. In some implementations, the SR content is updated as the user location changes or the user interacts with the SR content.

Method and device for tailoring a synthesized reality experience to a physical setting

Various implementations are disclosed of producing a 3-dimensional model of a scene. Various method, electronic device, or system implementations use RGB-D camera to provide RGB-D video content or periodic aligned RGB images and depth images to localize camera spatial position(s) defined in a three dimensional (3D) coordinate system or reconstruct a 3D virtual representation of a current camera frame in the 3D coordinate system, each in real time.
