摘要： User interactive methods of determining vertex correspondence between boundaries or curves on objects to be merged is provided. One method relates to projecting a boundary of one object onto a second object to determine a merging curve, along which the two objects will be joined. Another method includes projecting a first object onto a plane to form a planar curve. The planar curve is then mapped to a second object to form a merging curve. Still another method includes interactively selecting corresponding key vertices on different objects to form a merging curve. A system presented that can use one or more of the methods of determining correspondence between boundaries. A merged object can be generated from the merging curve using a mesh solver, such as a Poisson or non-Poisson mesh solver.

摘要： Pre-computed shadow fields are described. In one aspect, shadow fields for multiple entities are pre-computed. The shadow fields are pre-computed independent of scene configuration. The multiple entities include at least one occluding object and at least one light source. A pre-computed shadow field for a light source indicates radiance from the light source. A pre-computed shadow field for an occluding object indicates occlusion of radiance from the at least one light source.

摘要： Methods for synthesizing progressively-variant textures based on texton masks are provided. A first method creates a synthesized texture image guided by a sample texture, first texton mask corresponding to the sample texture and a second texton mask modified based on the first texton mask. A second method also creates a synthesized texture image guided by a first and second sample textures and corresponding first and second texton masks. A method for rendering a synthesized texture on an image of a three-dimensional object includes creating a synthesized texture on the object guided by a two-dimensional progressively-variant sample texture, a texton mask for the sample texture and a mesh of a plurality of vertices representing the object.

摘要： A system is described for using a texture synthesis approach to produce digital images that simulate motion. The system operates by receiving a large-scale motion image that describes large-scale motion, as well as one or more exemplar images that describes small-scale motion. The system then applies a texture synthesis approach to duplicate the small-scale motion described in the exemplar image(s), as guided by the large-scale motion described in the large-scale motion image. This operation produces a synthesized motion image. The system then combines the synthesized motion image with the large-scale motion image to produce a combined motion image. The combined motion image presents the large-scale motion as modulated by the small-scale motion. The system can also take account for one or more application-specific constraints, such as incompressibility and boundary conditions.

摘要： Described is a technology by which a ray tracer incorporates a GPU-based kd-tree builder for rendering arbitrary dynamic scenes. For each frame, the ray tracer builds a kd-tree for the scene geometry. The ray tracer spawns and traces eye rays, reflective and refractive rays, and shadow rays. For each ray to be traced, the ray tracer walks through the kd-tree until it reaches leaf nodes and associated triangles. When a ray passes through both sides of a splitting plane, the “far” sub-tree is pushed into the stack and the “near” sub-tree is traversed first.

摘要： Described is a technology in a computing environment comprising a programming language for general purpose computation on a graphics processing unit (GPU), along with an associated compiler. A Bulk-Synchronous GPU Programming (BSGP) program is programmed to include barriers to describe parallel processing on GPUs. A BSGP compiler detects barriers corresponding to supersteps, converts BSGP programs to kernels based on the barriers, and combines them. During compilation, the compiler aligns barriers in the statements and bundles the corresponding supersteps together. A par construct is provided to allow the programmer to control aspects of bundling, e.g., by specifying a block independent statements. Thread manipulation emulation is provided to transparently emulate thread creation and destruction, with operations fork and kill. Also provided is remote variable access intrinsics for efficient communications between threads, and collective primitive operations.

摘要： This disclosure describes a variational framework for detail-preserving skinned mesh manipulation or deformation. The skinned mesh deformation occurs by optimizing skeleton position and vertex weights of a skeletal skinned mesh in an integrated manner. The process allows creating new poses and animations by specifying a few desired constraints for the skeletal skinned mesh in an interactive deformation platform. This process adjusts the skeletal position and solves for a deformed skinned mesh simultaneously with an algorithm in conjunction with the constraints. The algorithm includes a cascading optimization procedure. The mesh puppetry displays skinned mesh manipulation in real-time.The user interface will enable interactive design in creating new poses and animations for a skeletal skinned mesh, enabling direct manipulation of the skeletal skinned mesh to create natural, life-like poses, and providing automatic balancing and most-rigid constraints to create a puppet-like animation.
