Simple stupid noise primitives for glam types (Vec2, Vec3) and wgsl.
Main motivations are:
simplex_noise_2d]simplex_noise_2d_seeded]simplex_noise_3d]fbm_simplex_2d]fbm_simplex_2d_seeded]fbm_simplex_3d]Zero initialization, just call the noise functions:
```rust use bevy::prelude::*; use noisybevy::simplexnoise_2d;
let p = Vec2::new(12.3, 45.6); let value = simplexnoise2d(p); ```
First add the plugin to the Bevy app:
rust ignore
App::new()
.add_plugin(NoisyShaderPlugin)
And import it and use it in your shaders, with the same API as on the CPU-side:
```wgsl
// ...
let p = vec2(12.3, 45.6); let value = simplexnoise2d(p); ```
See the asteroids example, for an example that uses noise to procedurally generate a tilemap on the CPU and a matching background in a wgsl shader.
The main branch targets the latest bevy release.

The original simplex noise source is MIT-only, however all changes made by me or PRs to this repo are also available under Apache-2.0.
The noise primitives are ports/copies of these
