Path tracer

Summary

A real-time 3D path tracing engine, running on the GPU, built with Rust and wgpu.

flying camera to move around
progressive rendering (If you stand still the engine will start to accumulate previous frames over time and average the pixels together, thus greatly reducing noise.)
converting equirectangular HDRIs to cubemaps (which can then be used for the skybox)
storing polygons in a Bounding Volume Hierarchy, so they can be traversed in logarithmic time
user interface for making changes at runtime, such as:
- adjusting the renderer's settings
- modifying the scene (adding and removing objects, modifying their properties, etc.)
selecting objects with the cursor (this currently only works for spheres, not complex meshes)
loading models from .obj files

saving and loading scene data
implementing textures
implementing a denoiser(?)
moving the whole thing to Vulkan, making it possible to utilize the raytracing cores on RTX GPUs
DLSS (??)

You will need the Rust toolchain. (You can install it using rustup.)

Running (in debug mode):

cargo run

Building in release mode:

cargo build --release
