Features of the latest mobile GPUs and the architecture of tile-based GPUs pro-

vide new and interesting ways to solve existing rendering problems. In this sec-

tion we will cover topics ranging from hybrid ray tracing to HDR computational

photography.

“Hybrid Ray Tracing on a PowerVR GPU” by Gareth Morgan describes how

an existing raster-based graphics engine can use ray tracing to add high-quality

effects like hard and soft shadows, reflection, and refraction while continuing to

use rasterization as the primary rendering method. The chapter also gives an

introduction to the OpenRL API.
