摘要： A computer graphics system generates a pixel value for a pixel in an image, the pixel value being representative of a point in a scene as recorded on an image plane of a simulated camera, the computer graphics system comprising a photon map generator, a sample point generator and a function evaluator. The photon map generator is configured to a plurality of photon maps, each photon map being associated with a respective point in time during a time interval. The sample point generator is configured to generate a set of sample points in accordance with a selected low-discrepancy sequence, each sample point representing a respective point in time during the time interval. The function evaluator is configured to generate at least one value representing an evaluation of a selected function using selected ones of the photon maps associated with respective ones of the points in time associated with the sample points generated by the sample point generator, the value generated by the function evaluator corresponding to the pixel value.

摘要： Systems and methods are provided for automated provisioning of managed resources in a distributed computing environment. Automated provisioning of managed resources is realized by systems and methods that support automated execution of provisioning workflows through programmatic invocation of provisioning tasks (sequentially and/or parallel invocation) supported by a provisioning system, as well as automated control and coordination of task execution and exception handling through automated message exchange. Systems and methods support automated provisioning through seamless integration of provisioning and change management systems, whereby provisioning systems can automatically interpret and execute reusable change plans that are generated (on-the-fly) by change management systems. The change plans comprise provisioning workflow processes that are described using a standard, platform-independent workflow language.

摘要： A ray tracer generates a ray tree, the ray tree comprising a primary ray shot along a selected direction and a plurality of other rays, the other rays being generated by recursive splitting. A ray is split when it encounters a predetermined condition, and each of the rays into which it is split is directed directed along a selected direction. The ray tracer comprises a low-discrepancy sequence generator an condition detector and a ray generator. The low-discrepancy sequence generator is configured to generate elements of at least one low-discrepancy sequence. The condition detector is configured to determine, for one of the rays in the ray tree, whether the one of the rays encounters the predetermined condition. The ray generator is configured to, when the condition detector makes a positive determination in connection with the one of the rays, generate a selected number “M” of split rays each along a splitting direction determined by a respective direction value determined in accordance with ( y i , j ) j = 0 M - 1 = ( Φ b d ⁡ ( i ) ⊕ j M , … ⁢ , Φ b d + Δ ⁢ ⁢ d - 1 ⁡ ( i ) ⊕ Φ b d + Δ ⁢ ⁢ d - 2 ⁡ ( j ) ) , where { Φ b d ⁡ ( i ) , … ⁢ , Φ b d + Δ ⁢ ⁢ d - 1 ⁡ ( i ) } ⁢ ⁢ and ⁢ ⁢ { j M , … ⁢ , Φ b d + Δ ⁢ ⁢ d - 2 ⁡ ( j ) } are low-discrepancy sequences, for selected bases b and dimensions Δd, generated by the low-discrepancy sequence generator, and where ⊕ represents addition modulo “one” and “i” is an instance number in connection with the one of the rays.

摘要： Computer-based methods and systems for performing automated distribution of a software package to one or more target machines in one or more regions of a distributed network of target machines, comprises the following steps. First, a base software package is prepared for each of the one or more regions based on at least one of: (i) policy data indicating which of the one or more regions are candidates for receiving the software package, (ii) dependency information indicating requisites for a service provided by the software package, and (iii) configuration information for each of the candidate regions. The base software package is then distributed to each of the candidate regions of the distributed network. The base software package received at each of the candidate regions is then customized based on at least one of: (i) regional distribution policies, (ii) dependency information specific to one or more roles performed by the target machines in that region, and (iii) individual target machine configuration information. Lastly, the software package customized in each of the candidate regions is distributed to at least one of the target machines in the candidate regions of the distributed network.

摘要： A snowboard binding that includes lock-retaining elements having sloping or conical surfaces for guiding the sole of a snow boot into a seated position. The boot sole becomes more restricted in the longitudinal and transverse directions, the further the boot is introduced into the binding, and a snowboard and a boot combination further having interengaging boot-retaining members on the binding and locking parts on the boot sole.

摘要： Embodiments of the present invention are directed to methods and a system that allow for deterministic parallel low discrepancy sampling, which can be efficiently processed, and are effective in removing transitionary artifacts that occur in low-dimensional projections generated in low discrepancy sequences. Embodiments of the claimed subject matter further provide improvements upon the low-dimensional projections and thus the visual quality when using the Sobol' sequence for image synthesis.
