Black Hole Ray Marching

This app uses ray marching, some maths from here and here and the Runge-Kutta method to simulate light rays around a black hole.

I started this app using the the Learn Wgpu tutorial. The user can control the camera and some settings.

Bloom using a Kawase dual filter is also implemented.

Using rust and WGPU (wgpu-rs), and wgsl shaders. Supports WASM.

Use cargo run to start.

Controls

• WASD, F and Space to move.
• Q and E to change speed.
• Press number keys and arrows to change shader uniforms.
• Hold F and the number keys to change maximum framerate.
