Building

First, you need to have a few things installed.

• Rust
• Vulkan SDK
• SDL2 if you're on Linux.

To build just use cargo build in the root directory.

ToDo

• Maybe switch out the cooley-tukey FFT with a Stockham implementation?
• Refactor SceneData cbuffer in shaders.
• Smooth the camera movement.
• Add better camera controls (e.g., only rotate when you're holding Ctrl + mouse movement).
• Figure out why the fragment shader outputs very pixelated(?) colors and fix that.
• Support window resizing + fullscreen.
• Support shader hot-reloading.
• Check Empirical directional wave spectra for computer graphics for better, more realistic waves.
• Add realistic shading of the ocean surface.
• Perhaps replace the simple skybox with something that simulates the sky based on Rayleigh scattering?
• Perhaps add a way to specify what the pipeline will look like from the shaders?
• [ ] Maybe do physical camera as is done here?
