摘要： An approach to enrich skeleton-driven animations with physically-based secondary deformation in real time is described. To achieve this goal, the technique described employs a surface-based deformable model that can interactively emulate the dynamics of both low- and high-frequency volumetric effects. Given a surface mesh and a few sample sequences of its physical behavior, a set of motion parameters of the material are learned during an off-line preprocessing step. The deformable model is then applicable to any given skeleton-driven animation of the surface mesh. Additionally, the described dynamic skinning technique can be entirely implemented on GPUs and executed with great efficiency. Thus, with minimal changes to the conventional graphics pipeline, the technique can drastically enhance the visual experience of skeleton-driven animations by adding secondary deformation in real time.

摘要： A computer implemented method for deforming a 3D polygon mesh using non-linear and linear constraints. The method includes creating a coarse control 3D polygon mesh that completely encapsulates the 3D polygon mesh to be deformed, projecting the deformation energy of the 3D polygon mesh and the constraints of the 3D polygon mesh to the vertices, or subspace, of the coarse control 3D polygon mesh, and determining the resulting deformed 3D polygon mesh by iteratively determining the deformation energy of the subspace. The constraints may be either linear or non-linear constraints, for example, a Laplacian constraint, a position constraint, a projection constraint, a skeleton constraint, or a volume constraint.

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.

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： An apparatus and method provide for providing an output image from an input image. The input image may contain at least one portion that does not display certain desired information of the image, such as texture information. The desired information may be obtained from a second portion of the input image and applied to the at least one portion that does not contain the texture information or contains a diminished amount of the texture information. Also, at least one characteristic of the second portion of the input image may not be applied to the at least one portion such as illumination information. In another example, the input image may be decomposed into multiple parts such as a high frequency and a low frequency component. Each component may be hallucinated individually or independently and combined to form the output image.
