  • Bounding volume hierarchy having oriented bounding boxes with quantized rotations
    Patent number: 12079919
    Abstract: Described herein is a technique for performing operations for a bounding volume hierarchy. The techniques include: for a bounding box with quantized orientation, the bounding box being part of a bounding volume hierarchy, rotating a ray according to the quantized orientation to generate a rotated ray; performing an intersection test against the bounding box with the rotated ray; and according to the results of the intersection test, continuing traversal of the bounding volume hierarchy.
    Type: Grant

  • Techniques for introducing oriented bounding boxes into bounding volume hierarchy
    Patent number: 11854138
    Abstract: Described herein is a technique for modifying a bounding volume hierarchy. The techniques include combining preferred orientations of child nodes of a first bounding box node to generate a first preferred orientation; based on the first preferred orientation, converting one or more child nodes of the first bounding box node into one or more oriented bounding box nodes; combining preferred orientations of child nodes of a second bounding box node to generate a second preferred orientation; and based on the second preferred orientation, maintaining one or more children of the second bounding box node as non-oriented bounding box nodes.
