Publication number: 20240104826Abstract: Techniques are disclosed for improving the throughput of ray intersection or visibility queries performed by a ray tracing hardware accelerator. Throughput is improved, for example, by releasing allocated resources before ray visibility query results are reported by the hardware accelerator. The allocated resources are released when the ray visibility query results can be stored in a compressed format outside of the allocated resources. When reporting the ray visibility query results, the results are reconstructed based on the results stored in the compressed format. The compressed format storage can be used for ray visibility queries that return no intersections or terminate on any hit ray visibility query. One or more individual components of allocated resources can also be independently deallocated based on the type of data to be returned and/or results of the ray visibility query.Type: ApplicationFiled: November 14, 2023Publication date: March 28, 2024Inventors: Gregory MUTHLER, John BURGESS, Ronald Charles BABICH, JR., William Parsons Newhall, JR.

Publication number: 20240095996Abstract: To improve the efficiency of bounding volumes in a hardware based ray tracer, we employ a sheared axis-aligned bounding box to approximate an oriented bounding box typically defined by rotations. To achieve this, the bounding volume hierarchy builder shears an axis-aligned box to fit tightly around its enclosed oriented geometry in top level or bottom level space, then computes the inverse shear transform. The bounds are still stored as axis-aligned boxes in memory, now defined in the new sheared coordinate system, along with the derived parameters to transform a ray into the sheared coordinate system before testing intersection with the boxes. The ray-bounding volume intersection test is performed as usual, just in the new sheared coordinate system.Type: ApplicationFiled: September 16, 2022Publication date: March 21, 2024Inventors: Gregory MUTHLER, John BURGESS, Eric ENDERTON, Nikhil DIXIT, Josh NOEL

Publication number: 20240087211Abstract: An alternate root tree or graph structure for ray and path tracing enables dynamic instancing build time decisions to split any number of geometry acceleration structures in a manner that is developer transparent, nearly memory storage neutral, and traversal efficient. The resulting traversals only need to partially traverse the acceleration structure, which improves efficiency. One example use reduces the number of false positive instance acceleration structure to geometry acceleration structure transitions for many spatially separated instances of the same geometry.Type: ApplicationFiled: September 9, 2022Publication date: March 14, 2024Inventors: Greg MUTHLER, John BURGESS, Magnus ANDERSSON, Timo VIITANEN, Levi OLIVER

Patent number: 11928772Abstract: In a ray tracer, to prevent any long-running query from hanging the graphics processing unit, a traversal coprocessor provides a preemption mechanism that will allow rays to stop processing or time out early. The example non-limiting implementations described herein provide such a preemption mechanism, including a forward progress guarantee, and additional programmable timeout options that can be time or cycle based. Those programmable options provide a means for quality of service timing guarantees for applications such as virtual reality (VR) that have strict timing requirements.Type: GrantFiled: August 17, 2022Date of Patent: March 12, 2024Assignee: NVIDIA CorporationInventors: Greg Muthler, Ronald Charles Babich, Jr., William Parsons Newhall, Jr., Peter Nelson, James Robertson, John Burgess

Publication number: 20240037841Abstract: Enhanced techniques applicable to a ray tracing hardware accelerator for traversing a hierarchical acceleration structure are disclosed. For example, traversal efficiency is improved by combining programmable traversals based on ray operations with per-node static configurations that modify traversal behavior. The per-node static configurations enable creators of acceleration data structures to optimize for potential traversals without necessarily requiring detailed information about ray characteristics and ray operations used when traversing the acceleration structure. Moreover, by providing for selective exclusion of certain nodes using per-node static configurations, less memory is needed to express an acceleration structure that includes, for example, different geometric levels of details corresponding to a single object.Type: ApplicationFiled: October 10, 2023Publication date: February 1, 2024Inventors: Gregory MUTHLER, John BURGESS

Publication number: 20240013471Abstract: Methods and systems are described in some examples for changing the traversal of an acceleration data structure in a highly dynamic query-specific manner, with each query specifying test parameters, a test opcode and a mapping of test results to actions. In an example ray tracing implementation, traversal of a bounding volume hierarchy by a ray is performed with the default behavior of the traversal being changed in accordance with results of a test performed using the test opcode and test parameters specified in the ray data structure and another test parameter specified in a node of the bounding volume hierarchy. In an example implementation a traversal coprocessor is configured to perform the traversal of the bounding volume hierarchy.Type: ApplicationFiled: September 21, 2023Publication date: January 11, 2024Inventors: Samuli LAINE, Timo AILA, Tero KARRAS, Gregory MUTHLER, William P.

Publication number: 20240009226Abstract: Ray tracing hardware accelerators supporting multiple specifiers for controlling the traversal of a ray tracing acceleration data structure are disclosed. For example, traversal efficiency and complex ray tracing effects can be achieved by specifying traversals through such data structures using both programmable ray operations and explicit node masking. The explicit node masking utilizes dedicated fields in the ray and in nodes of the acceleration data structure to control traversals. Ray operations, however, are programmable per ray using opcodes and additional parameters to control traversals. Traversal efficiency is improved by enabling more aggressive culling of parts of the data structure based on the combination of explicit node masking and programmable ray operations. More complex ray tracing effects are enabled by providing for dynamic selection of nodes based on individual ray characteristics.Type: ApplicationFiled: September 21, 2023Publication date: January 11, 2024Inventors: Gregory MUTHLER, John BURGESS

Publication number: 20230410410Abstract: A hardware-based traversal coprocessor provides acceleration of tree traversal operations searching for intersections between primitives represented in a tree data structure and a ray. The primitives may include opaque and alpha triangles used in generating a virtual scene. The hardware-based traversal coprocessor is configured to determine primitives intersected by the ray, and return intersection information to a streaming multiprocessor for further processing. The hardware-based traversal coprocessor is configured to provide a deterministic result of intersected triangles regardless of the order that the memory subsystem returns triangle range blocks for processing, while opportunistically eliminating alpha intersections that lie further along the length of the ray than closer opaque intersections.Type: ApplicationFiled: August 30, 2023Publication date: December 21, 2023Inventors: Samuli LAINE, Tero KARRAS, Greg MUTHLER, William Parsons Newhall, JR., Ronald Charles BABACH, JR., Ignacio LLAMAS, John BURGESS
