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, 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 raster-based API's, yet still obtain the benefits of physical rendering techniques.

摘要： Embodiments of the invention provide an efficient and flexible organization of data for an acceleration data structure (e.g., spatial index). In contrast to storing primitive information within a spatial index, embodiments of the invention may store pointers in the spatial index which point to or link to primitive-defining information in buffers. Storing pointers to primitive-defining information may reduce the size of the spatial index. Additionally, embodiments of the invention enable vertex and triangle sharing. Vertex and triangle sharing may reduce the amount of storage space required to define the primitives within the three-dimensional scene. Furthermore, the data organization provided by the embodiments of the invention allows for easy manipulation of the spatial index and primitive data.

摘要： A circuit arrangement and method support a multithreaded rendering architecture capable of dynamically routing pixel fragments from a pixel fragment generator to any pixel shader from among a pool of pixel shaders. The pixel fragment generator is therefore not tied to a specific pixel shader, but is instead able to utilize multiple pixel shaders in a pool of pixel shaders to minimize bottlenecks and improve overall hardware utilization and performance during image processing.

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.

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.
摘要翻译：在多线程电路布置中的硬件线程之间的电路布置，程序产品和方法流级别的细节组件来执行物理冲突检测。通常，主硬件线程（例如，组件加载器硬件线程）用于从存储器检索对象的细节数据级别，并将数据流传送到一个或多个从属硬件线程，例如冲突检测硬件线程，以执行实际碰撞检测。由于从属硬件线程接收到主线程的详细数据级别，通常从硬件线程不需要从存储器加载数据，从而减少内存带宽需求并加速性能。
