Tiny RTX

Description

This is a little experiment, mainly for learning about NVIDIA's Vk_NV_ray_tracing extension, which allows Real-Time Ray Tracing.

Requirements

This demo should run smooth on RTX cards, I've tested it with an external RTX 2070.

If you have a GTX card, then you might be able to run the demo as well, as NVIDIA recently added RTX emulation for some cards of the GTX series (but prepare for some sloppiness).

I recommend using the latest version of node, as this project heavily depends on BigInt, N-API, WebAssembly and ESM
