摘要： Aspects include API interfaces for interfacing shaders with other components and/or code modules that provide ray tracing functionality. For example, API calls may allow direct contribution of light energy to a buffer for an identified pixel, and allow emission of new rays for intersection testing alone or in bundles. The API also can provide a mechanism for associating arbitrary data with ray definition data defining a ray to be tested through a shader using the emit ray call. The arbitrary data is provided to a shader associated with an object that is identified subsequently as having been intersected by the ray. The data can include code, or a pointer to code, that can be used by or run after the shader. The data also can be propagated through a series of shaders, and associated with rays instantiated in each shader.

摘要： Aspects comprise systems implementing ray tracing functionality according to example architectures. In one example, rays are collected into collections against elements of an acceleration structure, which in some cases are associated with objects composing a scene being ray traced. Indications of detected ray intersections also can be collected in an output buffer, and in some examples, the output buffer can comprise a plurality of portions, each associated with a scene object, or a common portion of code to be executed during shading. Buffer contents can be accessed in a block read. An intersection shading resource can load data to be used in shading the intersections for the identified rays, and locally storing that data for use in shading those intersections.

摘要： For ray tracing scenes composed of primitives, systems and methods accelerate intersection testing by testing rays against elements of geometry acceleration data (GAD) arranged in a graph of nodes, where pairs of nodes are connected by edges, and each element bounds a varying granularity selection of the primitives. Upon detection of intersections between rays and elements, references to the rays are added to respective collections associated with the elements. Further processing of those rays is deferred until rays of a given collection are determined ready, and then rays from such a ready collection are tested for intersection with elements of GAD connected by edges to the element associated with the ready collection. When a primitive is bounded by no higher granularity GAD element, it is tested for intersection, and indications of intersection are output. Some examples encourage production of many secondary rays and collect such rays for parallelized testing, regardless of traversal order, camera ray association, or a time when each ray was spawned.

摘要： For ray tracing, methods, apparatus, and computer readable media provide efficient transmission and/or storage of rays between ray emitters, and an intersection testing resource. Ray emitters, during emission of a plurality of rays, identify a shared attribute of each ray of the plurality, and represent that attribute as shared ray data. The shared ray data, and other ray data sufficient to determine both an origin and a direction for each ray of the plurality, are transmitted. Functionality in the intersection testing resource receives the shared ray data and the other ray data, and interprets the shared ray data and the other ray data to determine an origin and direction for each ray of the plurality, and provides those rays for intersection testing. Rays can be stored in the shared attribute format in the intersection testing resource and data elements representing the rays can be constructed later. Programmable receiving functionality of the intersection testing resource can accommodate many ray types and other situations.

摘要： Aspects include a multistage collector to receive outputs from plural processing elements. Processing elements may comprise (each or collectively) a plurality of clusters, with one or more ALUs that may perform SIMD operations on a data vector and produce outputs according to the instruction stream being used to configure the ALU(s). The multistage collector includes substituent components each with at least one input queue, a memory, a packing unit, and an output queue; these components can be sized to process groups of input elements of a given size, and can have multiple input queues and a single output queue. Some components couple to receive outputs from the ALUs and others receive outputs from other components. Ultimately, the multistage collector can output groupings of input elements. Each grouping of elements (e.g., at input queues, or stored in the memories of component) can be formed based on matching of index elements.

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： In some aspects, systems and methods provide for forming groupings of a plurality of independently-specified computation workloads, such as graphics processing workloads, and in a specific example, ray tracing workloads. The workloads include a scheduling key, which is one basis on which the groupings can be formed. Workloads grouped together can all execute from the same source of instructions, one or more different private data elements. Such workloads can recursively instantiate other workloads that reference the same private data elements. In some examples, the scheduling key can be used to identify a data element to be used by all the workloads of a grouping. Memory conflicts to private data elements are handled through scheduling of non-conflicted workloads or specific instructions an deferring conflicted workloads instead of locking memory locations.

摘要： Aspects include computation systems that can identify computation instances that are not capable of being reentrant, or are not reentrant capable on a target architecture, or are non-reentrant as a result of having a memory conflict in a particular execution situation. A system can have a plurality of computation units, each with an independently schedulable SIMD vector. Computation instances can be defined by a program module, and a data element(s) that may be stored in a local cache for a particular computation unit. Each local cache does not maintain coherency controls for such data elements. During scheduling, a scheduler can maintain a list of running (or runnable) instances, and attempt to schedule new computation instances by determining whether any new computation instance conflicts with a running instance and responsively defer scheduling. Memory conflict checks can be conditioned on a flag or other indication of the potential for non-reentrancy.
