摘要： Aspects can be for ray tracing of 3-D scenes, and include dynamically controlling a population of rays being stored in a memory, to keep the population within a target, a memory footprint or other resource usage specification. An example includes controlling the population by examining indicia associated with rays returning from intersection testing, to be shaded, the indicia correlated with behavior of shaders to be run for those rays, such that population control selects, or reorders rays for shading, to prioritize shading of rays whose shaders are expected to produce fewer rays. The indicia can include a respective weight for each ray. In an example, analyzer modules examine hints associated with shaders bound to intersected primitives. Population control aspects can influence ray diversity in memory, including encouraging a varying diversity pattern as rendering of a given scene or frame progresses, based on system resource indicia, rendering metrics and so on.

摘要： In one aspect, photon queries are answered using systems and methods of traversal of collections of photon queries through an acceleration structure, to identify photons meeting a specification of a given query. Such systems and methods can be extended to satisfying similarity queries in an n-dimensional parameter space. Queries can be associated with code (or pointers to code) that are run to achieve closure of that query. Queries can cause further queries to be emitted. Arbitrary data can be passed from one query to another; for example, parameters defined internally to the code modules themselves (e.g., the parameters do not need to have a definition or meaning to the systems or within the methods).

摘要： Systems and methods for producing an acceleration structure provide for subdividing a 3-D scene into a plurality of volumetric portions, which have different sizes, each being addressable using a multipart address indicating a location and a relative size of each volumetric portion. A stream of primitives is processed by characterizing each according to one or more criteria, selecting a relative size of volumetric portions for use in bounding the primitive, and finding a set of volumetric portions of that relative size which bound the primitive. A primitive ID is stored in each location of a cache associated with each volumetric portion of the set of volumetric portions. A cache location is selected for eviction, responsive to each cache eviction decision made during the processing. An element of an acceleration structure according to the contents of the evicted cache location is generated, responsive to the evicted cache location.
摘要翻译：用于产生加速结构的系统和方法提供将3-D场景细分为具有不同大小的多个体积部分，每个体积部分可使用指示每个体积部分的位置和相对大小的多部分地址来寻址。通过根据一个或多个标准表征每个图元来处理图元流，选择用于界定图元的体积部分的相对大小，以及找到结合原始图像的相对尺寸的一组体积部分。原始ID存储在与该组体积部分的每个体积部分相关联的高速缓存的每个位置中。响应于在处理期间进行的每个缓存驱逐决定，选择缓存位置进行驱逐。响应于被驱逐的高速缓存位置，生成根据驱逐的高速缓存位置的内容的加速结构的元素。

摘要： Aspects include, for example, a method for interpreting information in a computer program, or profiling such a program to estimate a group size for instances of that program (program module, or portion thereof). Such a method can be used in a system that supports collecting outputs of executing instances, where those outputs can specify new program instances. Scheduling of new instances (or allocation of resources for executing such instances) can be deferred. A trigger to begin scheduling (or allocation) for a collection of instances uses a target group size for that program. Thus, different programs can have different group sizes, which can be set explicitly, or based on profiling. The profiling can occur during one or more of pre-execution and during execution. The group size estimate can be an input into an algorithm that also accounts for system state during execution.

摘要： Some aspects pertain to ray data storage for ray tracing rendering. Attribute data for a first ray can be stored. To define a second ray, data defining such can comprise a reference to the first ray (in one example) and attribute source information indicative of shared attributes between the first and second rays. The attribute source information can be shared among many rays, and can be selected based on ray type. Definition data for unshared attributes can be explicit with the second ray. A plurality of rays can reference one ray for shared attribute data. Referencing rays can be counted and decremented as referencing rays complete. Shared attributes can be indicated with masks. Interface modules can service ray data read and write requests made by shaders, and shaders can explicitly reference attributes of rays, without using such interfacing modules. Data structures can be used as attribute sources without being associated with particular rays, and can be defined and selected as attribute data sources based on ray type.

摘要： A synthetic acceleration shape bound primitives composing a 3-D scene, and is defined using a group of fundamental shapes arranged to bound the primitives, and for which intersection results for group members yield an ultimate intersection testing result for the synthetic shape, using a logical operator. For example, two or more spheres are used to bound an object so that each of the spheres is larger than a minimum necessary to bound the object, and a volume defined by an intersection between the shapes defines a smaller volume in which the object is bounded. A ray is found to potentially intersect the object only if it intersects both spheres. In another example, an element may be defined by a volumetric union of component elements. Indicators can determine how groups of shapes should be interpreted. Synthetic shapes can be treated as a single element in a graph or hierarchical arrangement of acceleration elements.

摘要： A graphics processor architecture provides for scan conversion and ray tracing approaches to visible surface determination as concurrent and separate processes. Surfaces can be identified for shading by scan conversion and ray tracing. Data produced by each can be normalized, so that instances of shaders, being executed on a unified shading computation resource, can shade surfaces originating from both ray tracing and rasterization. Such resource also may execute geometry shaders. The shaders can emit rays to be tested for intersection by the ray tracing process. Such shaders can complete, without waiting for those emitted rays to complete. Where scan conversion operates on tiles of 2-D screen pixels, the ray tracing can be tile aware, and controlled to prioritize testing of rays based on scan conversion status. Ray population can be controlled by feedback to any of scan conversion, and shading.
摘要翻译：图形处理器架构提供扫描转换和光线跟踪方法，将可视表面确定作为并行和单独的进程。可以通过扫描转换和光线跟踪来识别阴影的表面。由每个产生的数据可以被归一化，使得在统一的阴影计算资源上执行的着色器的实例可以遮蔽源自光线跟踪和光栅化的表面。这样的资源也可以执行几何着色器。着色器可以通过光线跟踪过程发射待测试的交叉点。这样的着色器可以完成，而不用等待那些发射的光线完成。在扫描转换对2-D屏幕像素的平铺进行扫描的地方，光线跟踪可以是平铺感知的，并且根据扫描转换状态来控制以优先考虑光线的优先级。可以通过反馈来控制光线群体的任何扫描转换和阴影。
