Abstract
Real time ray tracing-based adaptive multi frequency shading. For example, one embodiment of an apparatus comprising: rasterization hardware logic to process input data for an image in a deferred rendering pass and to responsively update one or more graphics buffers with first data to be used in a subsequent rendering pass; ray tracing hardware logic to perform ray tracing operations using the first data to generate reflection ray data and to store the reflection ray data in a reflection buffer; and image rendering circuitry to perform texture sampling in a texture buffer based on the reflection ray data in the reflection buffer to render an output image.
