NJU pbr 2021

This is a final project for NJU physically based rendering 2021 Sping. It is implemented in Rust and is by no means a mature renderer.

This project derives from @gkmngrgn 's work of implementing Peter Shirley's Ray Tracing trilogy in multiple languages. The previous project stopped at book 1 Raytracing in a weekend .

Core Features:

• Parallelism enabled by the fantastic Rust crate rayon.
• Convert source pixels of a logo image to a rendered one in 3D space.
• Enable triangles. Support mesh import. Support intersection.
• Metropolis sampling. [TODO]
• Acceleration: Bvh, Octree[TODO], KDTree[TODO].
• Texture. [TODO]
• Photon mapping. [TODO]

Usage:

• cargo build --release
• save logo to assets/base.png, run python3 proc.py. note that opencv-python and numpy packages are desired.
• mkdir result && time ./target/release/one_weekend > result/one_weekend.ppm for book one weekend, and time ./target/release/custom_img > result/nju.ppm for customized logo.
