bevy_compute_noise

A plugin for bevy 0.15 for generating tilable 2D/3D noise textures using compute shaders.

Check out a demo of the plugin here: https://jadedbay.com/demo/bevy_compute_noise (This demo currently uses v0.1.0)

Usage

Add the bevy_compute_noise dependency to Cargo.toml:

[dependencies]
bevy_compute_noise = "0.4.0"

Add Noise Plugin

use bevy_compute_noise::prelude::*;

App::default()
    .add_plugins(DefaultPlugins)
    .add_plugins(ComputeNoisePlugin) // Add compute noise plugin
    .run();

Write Noise to Image

fn setup(
    mut images: ResMut<Assets<Image>>,
    mut noise_queue: ResMut<ComputeNoiseQueue>
) {
    // Create image 
    let image = ComputeNoiseImage::create_image(ComputeNoiseSize::D2(512, 512));

    // Queue noise to be written to image
    noise_queue.write(
        image
        Perlin {
            seed: 0,
            frequency: 5.0,
            flags: (PerlinFlags::default() | PerlinFlags::TILEABLE).bits()
        }
    );
}

Noise Types

• Perlin
• Worley

FBM is available for all noise types, use Fbm<T: ComputeNoiseType>.

TODO

• Add more noise types.
• Allow combination of noise.
• Allow writing into specific texture channels.
