DISTRIBUTED LIGHT TRANSPORT SIMULATION WITH EFFICIENT RAY FORWARDING - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240355043 titled 'DISTRIBUTED LIGHT TRANSPORT SIMULATION WITH EFFICIENT RAY FORWARDING
The abstract describes a method for a compute node in a distributed light transport simulation to selectively forward rays to other compute nodes based on whether the graphical data assigned to those nodes has already been intersection-tested using the ray. This approach allows the compute node to avoid unnecessary ray forwarding, improving efficiency while maintaining flexibility in scene partitioning strategies.
- Compute nodes can determine which other nodes have already processed the graphical data assigned to them using the ray.
- Traversal information is used to indicate compute nodes that have or have not intersection-tested the ray.
- The compute node can replay traversal logic to generate lists of nodes that have or have not tested the ray.
Potential Applications: - Distributed light transport simulations - Ray tracing applications - High-performance computing environments
Problems Solved: - Reducing unnecessary ray forwarding in distributed simulations - Improving efficiency in scene partitioning strategies - Enhancing overall performance of light transport simulations
Benefits: - Increased efficiency in distributed computing environments - Flexibility in partitioning strategies - Reduction of redundant processing tasks
Commercial Applications: Title: "Efficient Distributed Light Transport Simulation Method" This technology can be applied in industries such as: - Animation and visual effects - Gaming - Scientific simulations
Questions about the technology: 1. How does this method improve the efficiency of distributed light transport simulations? 2. What are the key advantages of using traversal information to determine ray forwarding decisions?
Original Abstract Submitted
a compute node performing a distributed light transport simulation operation on a scene may select another compute node(s) for forwarding of a ray based on determining graphical data assigned to the other compute node(s) has already been intersection-tested using the ray. thus, the compute node can avoid forwarding the ray when the graphical data has already been processed using the ray, while providing flexibility in the partition strategy used to partition the scene amongst the compute nodes. the compute node may receive and/or determine traversal information indicating compute nodes that have already intersection-tested the ray and/or have not yet intersection-tested the ray. the traversal information may include a list of compute nodes that have or have not yet intersection-tested the ray. in some examples, the compute node replays the traversal logic used by the compute nodes to generate one or more portions of the list.
