Digital stages for presenting digital three-dimensional (3D) models are described. A service provider system, such as a content creation service provider system, supports generation of digital content based on incorporation of digital 3D models of objects into digital 3D environments. In particular, this model incorporation and digital content generation is supported by configuring 3D environments as 'stages,' which are implemented using data that describes characteristics of the digital 3D stages (e.g., background imagery, environment geometry, lighting, stage cameras, and so forth) according to a schema. Due to such configuration, the service provider can expose digital 3D stages for selection, incorporate digital 3D models at predefined positions within selected stages, and present views of incorporated models via the stages from predefined cameras. The service provider system thus enables client device users to simply select predefined positions and cameras, rather enter code to program 3D environments for presenting 3D objects.

Digital stages for presenting digital three-dimensional models

Transmission and configuration of three dimensional digital content is described. In one or more implementations, three-dimensional digital content is received having a three-dimensional mesh of a plurality of vertices. Each vertex includes a definition of a characteristic of the three-dimensional content. The definition of the characteristic is transformed for each vertex from a floating point representation to a fixed point representation. The fixed point representation includes a plurality of values that have different amounts of significance in defining the characteristic, one to another. The plurality of values is indexed of the fixed point representation of the definition of the characteristic. The indexing is based on the different amounts of significance, one to another. Output of the three dimensional digital content is controlled based on the indexed plurality of values.

Embodiments involve simulating sub-surface scattering of illumination for three-dimensional objects. An application determines, for each point defining a simulated three-dimensional surface, a respective first simulated light at the point caused by a simulated light source illuminating the three-dimensional surface. Each first simulated light includes a weighted average of simulated incident light at the point. Each weighted average is determined based on simulated incident light contributions from neighboring points of the three-dimensional surface. The application also determines, for each point, a respective second simulated light at the point. Each second simulated light includes light from the light source that is diffusively reflected at the point. The application also generates, for each point, a respective correction factor for the simulated light source to compensate for a difference between the first and second simulated lights by specifying a modification to color information generated based on the second simulated light.

The present disclosure includes systems and techniques relating to texture mapping a surface. In general, the subject matter described in this specification can be embodied in a computer-implemented method that includes defining a triangular mesh model of the surface; identifying at least one user-specified texture underfold constraint; computing a weighted energy functional for the triangular mesh, the weighted energy functional comprising a plurality of nodal texture values from which the triangular mesh is specified, the nodal texture values computed in accordance with the at least one user-specified texture underfold constraint; and iteratively recomputing the nodal texture values to converge the weighted energy functional toward a minimum value. The subject matter described in this specification can also be embodied in various corresponding computer program products, apparatus, and systems.

Method and apparatus for constraint-based texture generation

Systems and methods for generating 2D texture coordinates for 3D surfaces meshes may assign initial 2D texture coordinates to each node within a mesh using dead reckoning, compute a conformal mapping solution to revise the texture coordinates dependent on the initial mapping, and store the texture coordinates for subsequent use in a graphics application (e.g., applying a texture and/or re-meshing a surface). The methods may include designating one node as the origin, determining the shortest distance from each other node to the origin, and computing texture coordinates for each other node in order of increasing distance to the origin. The dead reckoning operation may compute texture coordinates of each node dependent on the distance and direction of a vector formed between the node and a neighbor node to which texture coordinates have already been assigned. Isometric terms reflecting stretching or compression may be introduced following convergence by the conformal mapping.
