Abstract: A proxy mesh that includes a plurality of proxy vertices is generated by projecting a visual mesh that includes a plurality of visual vertices onto a fitting plane. The visual mesh is of a character model. Each of the plurality of proxy vertices indicates a respective bone of the character model. A vertex weight associated with each of the plurality of proxy vertices of the proxy mesh is determined. Each of the vertex weights indicates how much the respective proxy vertex impacts a position of a visual vertex of the plurality of visual vertices that is adjacent to the respective proxy vertex. A position of each of the plurality of visual vertices is adjusted based on the determined vertex weights of a subset of the plurality of proxy vertices that are adjacent to the respective visual vertex.

Abstract: A plurality of UV patches of a three-dimensional model is divided into a primary set of the UV patches and a secondary set of the UV patches based on a patch size threshold. The UV patches of the primary set are grouped into a plurality of super-patches. Each of the plurality of super-patches includes different UV patches in the primary set that are packed together in a predefined shape. The plurality of super-patches is assembled together into a first bounding box. Poses of the plurality of super-patches are adjusted to reduce spacing between the plurality of super-patches. Gaps between the UV patches in the primary set are filled with the UV patches in the secondary set.

Abstract: A method is performed at a computing system for automatically generating an occluder, the method includes receiving an input model of the visual three-dimensional structure, the input model having a plurality of faces. The method includes simplifying the input model into an initial occluder including a plurality of candidate patches in a patch-based coarse mesh. The method includes determining a first quality metric of the initial occluder measured by a first number of pixels corresponding to objects behind the visual three-dimensional structure that are blocked by the input model and the initial occluder along a first view direction. The method includes removing one or more candidate patches associated with the first number of pixels from the initial occluder while maintaining the first quality metric above a first threshold to form the occluder for the visual three-dimensional structure.
