Overview

The goal of this project is to research and implement modern techniques for rendering large scenes. The code is intended to serve as a reference for others wanting to build their own renderers and template for my own explorations.

Features

• GPU driven rendering
• Compute based frustum culling
• Instancing for reduced memory usage
• Deferred renderer architecture
• LTC based arealights
• TAA
• Handwritten BVH with SAH and TLAS over it for instanced rendering

TODO

[ ] Raytraced shadows for arealights

Building

Run cargo build --release from the main repository directory. Don't forget the --release since debug builds in Rust will run slowly.
