Abstract: A method of compressing meshes using a projection-based approach, and leveraging the tools and syntax already generated for projection-based point cloud compression is described herein. Similar to the V-PCC approach, the mesh is segmented into surface patches, only the difference is that the segments follow the connectivity of the mesh. Each surface patch (or 3D patch) is then projected to a 2D patch, whereby in the case of the mesh, the triangle surface sampling is similar to a common rasterization approach used in computer graphics. For each patch, the position of the projected vertices is kept in a list, along with the connectivity of those vertices. The sampled surface now resembles a point cloud, and is coded with the same approach used for point cloud compression. Additionally, the list of vertices and connectivity is encoded per patch, and this data is sent along with the coded point cloud data.

Abstract: A color mapping technique that provides an intuitive visualization of surface normals is described. The surface normals can be associated with a mesh for a virtual object to be displayed in augmented reality. The color mapping technique can map a unit sphere in a color space to an octahedron. The vertices of the octahedron can be aligned with prime colors of the color space. To perform the alignment, a rotation and shear matrix can be determined from coordinates for octahedron positions and coordinates of colors in the color space. The rotation and shear can provide that each region of the unit color sphere is dominated by a single prime color, with gradients between prime colors being visually balanced. Surface normals of a mesh for a virtual object can be visualized using the color mapping, and a viewer can readily determine how distant in terms of rotation two surface normals are from each other.
