摘要： A method, program product and system for conducting a ray tracing operation where the rendering compute requirement is reduced or otherwise adjusted in response to a changing vantage point. Aspects may update or reuse an acceleration data structure between frames in response to the changing vantage point. Tree and image construction quality may be adjusted in response to rapid changes in the camera perspective. Alternatively or additionally, tree building cycles may be skipped. All or some of the tree structure may be built in intervals, e.g., after a preset number of frames. More geometric image data may be added per leaf node in the tree in response to an increase in the rate of change. The quality of the rendering algorithm may additionally be reduced. A ray tracing algorithm may decrease the depth of recursion, and generate fewer cast and secondary rays. The ray tracer may further reduce the quality of soft shadows, resolution and global illumination samples, among other quality parameters. Alternatively, tree rebuilding may be skipped entirely in response to a high camera rate of change. Associated processes may create blur between frames to simulate motion blur.

摘要： A circuit arrangement, program product and method stream level of detail components between hardware threads in a multithreaded circuit arrangement to perform physics collision detection. Typically, a master hardware thread, e.g., a component loader hardware thread, is used to retrieve level of detail data for an object from a memory and stream the data to one or more slave hardware threads, e.g., collision detection hardware threads, to perform the actual collision detection. Because the slave hardware threads receive the level of detail data from the master thread, typically the slave hardware threads are not required to load the data from the memory, thereby reducing memory bandwidth requirements and accelerating performance.

摘要： A circuit arrangement and method provide a hybrid rendering architecture capable of interfacing a streaming geometry frontend with a physical rendering backend using a dynamic accelerated data structure (ADS) generator. The dynamic ADS generator effectively parallelizes the generation of the ADS, such that an ADS may be built using a plurality of parallel threads of execution. By doing so, both the frontend and backend rendering processes are amendable to parallelization, and enabling if so desired real time rendering using physical rendering techniques such as ray tracing and photon mapping. Furthermore, conventional streaming geometry frontends such as OpenGL and DirectX compatible frontends can readily be adapted for use with physical rendering backends, thereby enabling developers to continue to develop with known API's, yet still obtain the benefits of physical rendering techniques.
摘要翻译：电路布置和方法提供了能够使用动态加速数据结构（ADS）发生器将流几何前沿与物理渲染后端连接的混合渲染架构。动态ADS发生器有效地并行化ADS的生成，使得可以使用多个并行执行线程构建ADS。通过这样做，前端和后端渲染过程可以修改为并行化，并且如果需要使用诸如光线跟踪和光子映射之类的物理渲染技术的实时渲染，则使能。此外，诸如OpenGL和DirectX兼容的前端之类的常规流几何前端可以容易地适用于物理渲染后端，从而使开发人员可以继续使用已知的API进行开发，但是仍然可以获得物理渲染技术的优点。

摘要： A circuit arrangement and method perform concurrent texture processing of groups of pixels with a single instruction multiple data (SIMD) execution unit to improve the utilization of the SIMD execution unit when performing scalar operations associated with a texture processing algorithm. In addition, when utilized in connection with a multi-threaded SIMD execution unit, groups of pixels may be concurrently processed in different threads executed by the SIMD execution unit to further maximize the utilization of the SIMD execution unit by reducing the adverse effects of dependencies in scalar and/or vector operations incorporated into a texture processing algorithm.
