摘要： In an example, ray tracing scenes includes 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 ray identifiers. A shading to testing queue comprises identifiers of new rays for test, 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, being selectable for testing multiple times based on ray identifier. A structure of acceleration shapes can be used. Packets of ray identifiers and shape data can circulate among intersection testing resources, each resource can test rays identified in the packet, and for which definition data is present in its memory. Acceleration shape test results allow collection of rays based on intersected shape, and closest detection ray/primitive intersections are indicated by queuing ray identifiers for shading.

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.

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.
