1. An apparatus, comprising:
ray intersection accelerator circuitry configured to:
determine a ray time interval representation indicating upper and lower bounds that represent error bounds for a quantized ray time value of a ray; and
perform traversal operations for an acceleration data structure (ADS) that includes hierarchical bounding volumes, wherein the ADS includes a first node that specifies:
first coordinates of a bounding volume at a first motion blur time; and
second coordinates of the bounding volume at a second motion blur time;
wherein the ray intersection accelerator circuitry includes:
interpolation circuitry configured to operate on the first coordinates, the second coordinates, and the ray time interval representation to generate interpolated coordinates for the bounding volume; and
box test circuitry configured to determine whether the ray intersected the bounding volume based on the interpolated coordinates and coordinates of the ray.
