摘要： Aspects include systems, methods, and media for implementing methods relating to increasing consistency of results during intersection testing. In an example, vertexes define edges of primitives composing a scene (e.g., triangles defining a mesh for a surface of an object in a 3-D scene). An edge can be shared between two primitives. Intersection testing algorithms can use tests involving edges to determine whether or not the ray intersects a primitive defined by those edges. In one approach, a precedence among the vertexes defining a particular edge is enforced for such intersection testing. The precedence causes an intersection tester to always test a given edge in the same orientation, regardless of which primitive defined (at least in part) by that edge is being intersection tested.

摘要： Ray tracing, and more generally, graphics operations taking place in a 3-D scene, involve a plurality of constituent graphics operations. Scheduling of graphics operations for concurrent execution on a computer may increase throughput. In aspects herein, constituent graphics operations are scheduled in groups, having members selected according to disclosed aspects. Processing for specific graphics operations in a group can be deferred if all the operations in the group cannot be further tested concurrently. Graphics operations that have been deferred are recombined into two or more different groups and ultimately complete processing, through a required number of iterations of such process. In one application, the performance of the graphics operations perform a search in which respective 1:1 matches between different types of geometric shapes involved in the 3-D scene are identified. For example, closest intersections between rays and scene geometry can be identified by processing scheduled according to disclosed aspects.

摘要： Ray tracing scenes is accomplished using a plurality of intersection testing resources coupled with a plurality of shading resources, communicative in the aggregate through links/queues. A queue from testing to shading comprises respective ray/primitive intersection indications, comprising a ray identifier. A queue from shading to testing comprises identifiers of new rays to be tested, wherein data defining the rays is separately stored in memories distributed among the intersection testing resources. Ray definition data can be retained in distributed memories until rays complete intersection testing, and be selected for testing multiple times based on ray identifier. A structure of acceleration shapes can be used. Packets of ray identifiers and shape data can be passed among the intersection testing resources, and each resource can test rays identified in the packet, and for which definition data is present in its memory. Test results for acceleration shapes are used to collect rays against acceleration shapes, and closest detection ray/primitive intersections are indicated by sending ray identifiers to shading resources.

摘要： Systems, methods, and computer readable media embodying such methods provide for allowing specification of per-ray clipping information that defines a sub-portion of a 3-D scene in which the ray should be traced. The clipping information can be specified as a clip distance from a ray origin, as an end value of a parametric ray definition, or alternatively the clipping information can be built into a definition of the ray to be traced. The clipping information can be used to check whether portions of an acceleration structure need to be traversed, as well as whether primitives should be tested for intersection. Other aspects include specifying a default object that can be returned as intersected when no primitive was intersected within the sub-portion defined for testing. Further aspects include allowing provision of flags interpretable by an intersection testing resource that control what the intersection testing resource does, and/or what information it reports after conclusion of testing of a ray.
