| 20090096788 | METHOD AND APPARATUS FOR INCREASING EFFICIENCY OF TRANSMISSION AND/OR STORAGE OF RAYS FOR PARALLELIZED RAY INTERSECTION TESTING - 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. | 04-16-2009 |
| 20090096789 | METHOD, APPARATUS, AND COMPUTER READABLE MEDIUM FOR LIGHT ENERGY ACCOUNTING IN RAY TRACING - For ray tracing systems, described methods, media, apparatuses provide for accounting of light energy that will be collected at pixels of a 2-D representation without recursive closure of a tree of ray/primitive intersections, and also provide for adaptivity in ray tracing based on importance indicators of each ray, such as a weight, which may be carried in data structures representative of the rays. Examples of such adaptivity may include determining a number of children to issue for shading an identified intersecting primitive, culling rays, and adding rays to achieve more accurate sampling, if desired. All such adaptivity may be triggered with goal-based indicators, such as a threshold value representative of rendering progress to a time-based goal, such as a frame rate. | 04-16-2009 |
| 20090128562 | SYSTEMS AND METHODS FOR RENDERING WITH RAY TRACING - For ray tracing scenes composed of primitives, systems and methods accelerate ray/primitive intersection identification by testing rays against elements of geometry acceleration data (GAD) in a parallelized intersection testing resource. Groups of rays can be described as shared attribute information and individual ray data for efficient ray data transfer between a host processor and the testing resource. The host processor also hosts shading and/or management processes controlling the testing resource and adapting the ray tracing, as necessary or desirable, to meet criteria, while reducing degradation of rendering quality. The GAD elements can be arranged in a graph, and rays can be collected into collections based on whether a ray intersects a given element. When a collection is deemed ready for further testing, it is tested for intersection with GAD elements connected, in the graph, to the given element. The graph can be hierarchical such that rays of a given collection are tested against children of the GAD element associated with the given collection. | 05-21-2009 |
| 20090284523 | METHOD, APPARATUS, AND COMPUTER READABLE MEDIUM FOR ACCELERATING INTERSECTION TESTING IN RAY-TRACING RENDERING - 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. | 11-19-2009 |
