  • Publication number: 20250022216
    Abstract: In various examples, shader bindings may be recorded in a shader binding table that includes shader records. Geometry of a 3D scene may be instantiated using object instances, and each may be associated with a respective set of the shader records using a location identifier of the set of shader records in memory. The set of shader records may represent shader bindings for an object instance under various predefined conditions. One or more of these predefined conditions may be implicit in the way the shader records are arranged in memory (e.g., indexed by ray type, by sub-geometry, etc.). For example, a section selector value (e.g., a section index) may be computed to locate and select a shader record based at least in part on a result of a ray tracing query (e.g., what sub-geometry was hit, what ray type was traced, etc.).

  • Patent number: 12152346
    Abstract: A paperboard structure that includes a paperboard substrate which includes a first major side and a second major side along with at least one barrier coating layer on the first major side. The barrier coating layer(s) may include a binder and a pigment, wherein the binder has a glass transition temperature of at least 20° C., wherein a ratio of the binder to the pigment is at least about 1:2 by weight.

  • Publication number: 20240355043
    Abstract: 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.

  • Publication number: 20240080041
    Abstract: In various examples, metadata may be generated corresponding to compressed data streams that are compressed according to serial compression algorithms—such as arithmetic encoding, entropy encoding, etc.—in order to allow for parallel decompression of the compressed data. As a result, modification to the compressed data stream itself may not be required, and bandwidth and storage requirements of the system may be minimally impacted. In addition, by parallelizing the decompression, the system may benefit from faster decompression times while also reducing or entirely removing the adoption cycle for systems using the metadata for parallel decompression.

  • Patent number: 11697908
    Abstract: A method for manufacturing a paperboard structure includes passing a paperboard substrate through a hot-hard calender to yield a calendered paperboard substrate, the hot-hard calender including a nip defined by a thermo-roller and a counter roller, wherein a contact surface of the thermo-roller is heated to an elevated temperature. The method then includes applying a basecoat to the calendered paperboard substrate to yield a basecoated paperboard substrate, the basecoat includes a basecoat binder and a basecoat pigment blend. The method further includes applying a topcoat to the basecoated paperboard substrate.
