Abstract: In implementations of systems for spatially coherent UV packing, a computing device implements a packing system to identify pairs of boundary vertices of different two-dimensional islands included in a set of two-dimensional islands. A first boundary vertex and a second boundary vertex of the pairs of boundary vertices both correspond to a same three-dimensional coordinate of a three-dimensional mesh. The packing system determines transformations for two-dimensional islands included in the set of two-dimensional islands based on distances between the first boundary vertex and the second boundary vertex of the pairs of boundary vertices. A three-dimensional object is generated for display in a user interface based on the transformations and the three-dimensional mesh.

Abstract: Described herein are techniques for segmenting a mesh to reduce or remove elongated shapes, to enable texturing a three-dimensional (3D) mesh. An embodiment described is a method in which one or more processing devices perform operations that include accessing segments of the 3D mesh and detecting that a first segment is elongated. The operations include modifying the segments of the 3D mesh by subdividing the first segment into two or more sub-segments, based on the first segment being elongated. The operations include assigning, for each 3D vertex of the two or more sub-segments, respective two-dimensional (2D) coordinates in a texture map. The operations further include applying a texture to the 3D mesh. Application of the texture involves mapping the 3D vertices of the two or more sub-segments based on the respective 2D coordinates corresponding to the 3D vertices of the two or more sub-segments according to the texture map.

Abstract: The present disclosure relates to systems, methods, and non-transitory computer readable media for generating and providing a height map of a three-dimensional digital model based on a normal map of the three-dimensional digital model. For example, the disclosed systems can generate a height map from a normal map by utilizing a Poisson model based on Dirichlet boundary conditions. The disclosed systems can determine the Dirichlet boundary conditions for a virtual boundary of a gradient map corresponding to a given normal map by imposing pure Neumann boundary conditions for the virtual boundary. Based on the Dirichlet boundary conditions, the disclosed systems can utilize a Poisson model to determine height values for pixels of a gradient map corresponding to pixels of a given normal map.
