Abstract: A graphical user interface (GUI) is configured for displaying surfaces of simulated objects within a scene. The GUI comprises a selector to choose between displaying the scene as: a plurality of particles, wherein each particle comprises a plurality of attributes; a plurality of ellipsoids formed from the plurality of particles, wherein dimensions and orientation of each ellipsoid depend on the number and direction of neighboring ellipsoids within a search radius of the ellipsoid; or one or more splatted or rasterized surfaces formed from the plurality of ellipsoids. The GUI further includes a display window within which the GUI displays the scene.

Abstract: A method for generating visual representations of interactions between two different materials is provided. The method can be performed using a computing device operated by a computer user or artist. The method includes modeling a primary material as a plurality of first particles and modeling a layer portion of a secondary material as a fluid volume. The secondary material can include a layer portion positioned between the plurality of first particles and an outer portion. At least one boundary condition might be assigned to a boundary positioned between the layer portion and the outer portion, the at least one boundary condition includes at least one pressure value. Values of motion parameters might be determined by applying the at least one boundary condition at the boundary and generating one or more visual representations of the primary material interacting with the secondary material based on the values of the motion parameters.

Abstract: A simulator computes surfaces corresponding to objects in a simulation by computing covariance matrices for particles that use a square root of a diagonal matrix. The simulator might operate by receiving positions and sizes for each particle of a plurality of particles comprising a first object, identifying a subset of the plurality of particles whose positions are proximate to a first surface of the first object, deforming particles of the subset of the plurality of particles by generating a covariance matrix for each particle of the plurality of particles, using a square root of a diagonal matrix, wherein the diagonal matrix is a diagonal matrix of neighboring particles for each particle of the plurality of particles, and computing the first surface of the first object based on the deformed particles.

Abstract: A data processing system has an execution pipeline with programmable execution stages which execute instructions to perform data processing operations provided by a host processor and in which execution threads are grouped together into groups in which the threads are executed in lockstep. The system also includes a compiler that compiles programs to generate instructions for the execution stages. The compiler is configured to, for an operation that comprises a memory transaction: issue to the execution stage instructions for executing the operation for the thread group to: perform the operation for the thread group as a whole; and provide the result of the operation to all the active threads of the group. At least one execution stage is configured to, in response to the instructions: perform the operation for the thread group as a whole; and provide the result of the operation to all the active threads of the group.

Abstract: A graphics processing unit comprises a programmable execution unit executing graphics processing programs for execution threads to perform graphics processing operations, a local register memory comprising one or more registers, where registers of the register memory are assignable to store data associated with an individual execution thread that is being executed by the execution unit, and where the register(s) assigned to an individual execution thread are accessible only to that associated individual execution thread, and a further local memory that is operable to store data for use in common by plural execution threads, where the data stored in the further local memory is accessible to plural execution threads as they execute. The programmable execution unit is operable to selectively store output data for an execution thread in a register(s) of the local register memory assigned to the execution thread, and the further local memory.

Abstract: Described herein is a substrate including a central longitudinal axis, a first support web, and a second support web. A sinuous web may be positioned between the first support web and the second support web. The sinuous web may include transverse web portions and bridging web portions, where the bridging web portions alternatively connect ends of adjacent transverse web portions. The sinuous web may be connected to the first support web by support legs extending between bridging web portions and a surface of the first support web. The sinuous web may be connected to the second support web by support legs extending between bridging web portions and a surface of the second support web. A support leg length to distance between transverse web portions ratio may be from about 1.0 to about 4.0.

Abstract: The fuel distribution system with correction mechanism includes systems and methods for distributing fuel at a plurality of fuel pumps. Fuel is distributed at a first fuel pump and at a second fuel pump. Erroneously, multiple payments are received for the distribution of fuel at the first fuel pump. One of the multiple payments is applied to an outstanding transaction of the second fuel pump. The difference amount between the payment applied to the second fuel pump and an amount associated with the outstanding transaction of the second fuel pump is calculated and resolved.

Abstract: A processing apparatus comprising: several processors for processing data; a hierarchical memory system comprising a memory accessible to all the processors, and several caches corresponding to each of the processors, each of the caches being accessible to the corresponding processor and comprising storage locations and corresponding indicators. There is also cache coherency control circuitry for maintaining coherency of data stored in the hierarchical memory system. The processors are configured to respond to receipt of a predefined request to perform an operation on a data item to determine if the cache corresponding to the processor receiving the request has a storage location allocated to the data item. If not, the processing apparatus is configured to: allocate a storage location within the cache to the data item, set the indicator corresponding to the storage location to indicate that the storage location is storing a delta value, set data in the allocated storage location to an initial value.
