摘要： A method and system for performing a texture operation with user-specified offset positions are disclosed. Specifically, one embodiment of the present invention sets forth a method, which includes the steps of deriving a first destined texel position based on an original sample position associated with a pixel projected in a texture map and a first offset position specified by a user and fetching texel attributes at the first destined texel position for the texture operation.

摘要： One embodiment of the present invention sets forth a technique for performing dual depth peeling, which is useful for order-independent transparency blending. Multiple rendering passes are performed on a graphics scene. After each rendering pass, the front-most and back-most layer of pixels are peeled away by computing a reference window. In subsequent rendering passes, only pixels within the reference window survive depth sorting. In each subsequent rendering pass, the reference window is narrowed by the front most and back most surviving pixels. By performing depth peeling in two directions simultaneously, the number of rendering passes needed to generate a completed graphics image is reduced from L to 1+L/2, which results in improved rendering performance.
摘要翻译：本发明的一个实施例提出了一种用于进行双重深度剥离的技术，其对于与订单无关的透明度混合是有用的。在图形场景上执行多个渲染通过。在每次渲染通过之后，通过计算参考窗口将最前面和最后面的像素层剥离掉。在随后的渲染遍历中，只有参考窗口中的像素才能深入排序。在每个随后的渲染遍历中，参考窗口被前面和后面最幸存的像素缩小。通过同时进行两个方向的深度剥离，生成完成的图形图像所需的渲染次数从L减少到1 + L / 2，这导致改善的渲染性能。

摘要： Systems and methods for storing high dynamic range image data in a low dynamic range format may be used to store the high dynamic range image data in less memory. The memory bandwidth needed to access the high dynamic range data is reduced and processing performance may be improved when performance is limited by memory bandwidth. The high dynamic range image data is scaled and compressed into a low dynamic range format for storage in a render target. If the compressed high dynamic range image data contains multiple data samples per pixel, the data may be processed to produce filtered compressed high dynamic range image data with only one sample per pixel. The high dynamic range image may be reconstructed from the low dynamic range format data and further processed as high dynamic range format data for a range of applications.
摘要翻译：用于以低动态范围格式存储高动态范围图像数据的系统和方法可用于在较少存储器中存储高动态范围图像数据。降低访问高动态范围数据所需的存储器带宽，并且当性能受到存储器带宽的限制时，可以提高处理性能。高动态范围图像数据被缩放并压缩成低动态范围格式以存储在渲染目标中。如果压缩的高动态范围图像数据包含每像素多个数据样本，则可以处理数据以产生仅具有每像素一个采样的滤波压缩的高动态范围图像数据。高动态范围图像可以从低动态范围格式数据重建，并且作为用于一系列应用的高动态范围格式数据被进一步处理。
