CPU Rendering of Large Volumetric Data

This work examines direct rendering of large volumetric data on the CPU. The aim was to design a parallel implementation of Ray casting algorithm in the Rust programming language and to implement Early Ray Termination and Empty Space Skipping optimizations to speed up rendering. I also designed a demo application to interactively display volumes using this algorithm. A volumetric data generator was also created as part of the work.Both optimizations in the resulting solution offer a 12× speed up. Parallelization further improves this number and renders a large volume at 3.92 FPS on the tested system.
