PROCESSOR AND METHOD FOR ACCELERATING RAY CASTING

摘要

A processor and method for accelerating ray casting are disclosed herein. The processor for accelerating ray casting includes a computation unit, a sorting unit, an allocation unit, and an execution control unit. The computation unit calculates the length information of a section in which a ray corresponding to each of the pixels of a two-dimensional (2D) scene corresponding to a viewpoint intersects an effective volume in order to apply ray casting to the pixel. The sorting unit sorts the ray based on the length information of the section in which the ray intersects the effective volume. The allocation unit allocates the sorted rays to respective thread groups having a parallel multiprocessor structure in order of the sorting. The execution control unit transfers control instructions to the allocated thread groups so that the allocated thread groups execute ray casting for the sorted rays.

1. A method of accelerating ray casting in a computing system, comprising:
calculating, by a processor in the computing system, length information of a section in which a ray corresponding to each pixel of a two-dimensional (2D) scene corresponding to a viewpoint intersects an effective volume in order to apply ray casting to the pixel; sorting, by the processor, the ray based on the length information of the section in which the ray intersects the effective volume; and allocating, by the processor, the sorted rays to thread groups having a parallel multiprocessor structure in order of the sorting.
