摘要： Gradient domain editing of animated meshes is described. Exemplary systems edit deforming mesh sequences by applying Laplacian mesh editing techniques in the spacetime domain. A user selects relevant frames or handles to edit and the edits are propagated to the entire sequence. For example, if the mesh depicts an animated figure, then user-modifications to position of limbs, head, torso, etc., in one frame are propagated to the entire sequence. In advanced editing modes, a user can reposition footprints over new terrain and the system automatically conforms the walking figure to the new footprints. A user-sketched curve can automatically provide a new motion path. Movements of one animated figure can be transferred to a different figure. Caricature and cartoon special effects are available. The user can also select spacetime morphing to smoothly change the shape and motion of one animated figure into another over a short interval.

摘要： A graphics system allows for manipulation of a detail mesh for a subdivision surface. To deform the subdivision surface, the graphics system generates a corresponding deformed control mesh by attempting to satisfy both position constraints of the manipulation and Laplacian constraints for the detail mesh. After the deformed control mesh is generated, the deformed detail mesh can be generated by applying a subdivision function to the deformed control mesh to generate a deformed smooth mesh and then applying detail information to the deformed smooth mesh.

摘要： A method and system is provided for deforming a shape of an image. In one example, an input is received for deforming a displayed shape, the shape including a boundary polygon or outline contour and a local area within the outline contour. The local area may further include vertices and edges. During deformation, an energy function corresponding to the outline contour and the local area may be determined and reduced or minimized. Positioning of the vertices and lengths of the edges may be determined based on the energy function or preservation of coordinates associated with the outline contour and the local area.

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.
