Abstract: A technique for performing ray tracing operations is provided. The technique includes traversing a bounding volume hierarchy for a ray to arrive at a bounding box without use of a neural network; perform a feature vector lookup using modified polar coordinates characterizing the ray relative to the bounding box to obtain a set of feature vectors; and obtaining output with the neural network using the set of feature vectors.
