[Bevy](https://github.com/bevyengine/bevy) that renders volumetric clouds\nusing the method of Horizon Zero Dawn by Guerilla Games (see [credits](#credits)).\n\n## Usage\n\nRun `cargo add bevy-volumetric-clouds` and simply add `CloudsPlugin` to your Bevy App like this:\n\n```rust ignore\nuse bevy_volumetric_clouds::CloudsPlugin;\n\napp.add_plugins(CloudsPlugin);\n```\n\nLook at [the minimal example](examples/minimal.rs) for a working example.\n\nThe [the demo example](examples/demo.rs) features a usable demo where you can move the camera around\nand use a UI to change the configuration of the cloud rendering\n(if you run it with the `fly_camera` and `debug` features):\n\n```sh\ncargo run --example demo --features fly_camera,debug\n```\n\nThe configuration of the clouds rendering can be changed using the `CloudsConfig` resource.\nSee [its docs](https://docs.rs/bevy-volumetric-clouds/latest/bevy_volumetric_clouds/config/struct.CloudsConfig.html) for more information.\n\n## Limitations\n\nA few limitations apply for now and hopefully get fixed in the future:\n\n- There is no integration with Bevy's internal atmosphere rendering yet, this plugin uses a simple\n  sky rendering function.\n- The clouds are drawn on a skybox that does not take the depth buffer into account yet. Therefore,\n  it's not yet possible to \"fly\" into the clouds, the clouds are only visible from ground-level.\n- For now the clouds render resolution is set to 1920x1080 and can't be changed.\n  Usually clouds are rendered at a lower resolution than screen resolution so you likely won't need\n  a higher resolution anyway but changing the resolution should be possible in the future.\n\n## Crate features\n\nThere are a few features:\n\n- `debug`: enables an `egui` UI that allows you to tweak shader uniforms (parameters) in-game.\n- `fly_camera`: adds a `fly_camera` module that controls the camera using keyboard and mouse.\n\n## Bevy version compatibility\n\n| bevy | bevy-volumetric-clouds |\n|------|------------------------|\n| 0.18 | 0.2.*                  |\n| 0.17 | 0.1.*                  |\n\n## Credits\n\n1. \"The real-time volumetric cloudscapes of Horizon Zero Dawn\" by Andrew Schneider and Nathan Vos ([article](https://www.guerrilla-games.com/read/the-real-time-volumetric-cloudscapes-of-horizon-zero-dawn))\n2. \"Physically Based Sky, Atmosphere and Cloud Rendering in Frostbite\" by Sébastien Hillaire ([pdf](https://media.contentapi.ea.com/content/dam/eacom/frostbite/files/s2016-pbs-frostbite-sky-clouds-new.pdf))\n\n## License\n\nLicensed under [MIT](https://choosealicense.com/licenses/mit/), see [LICENSE](./LICENSE).\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fevroon%2Fbevy-volumetric-clouds","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fevroon%2Fbevy-volumetric-clouds","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fevroon%2Fbevy-volumetric-clouds/lists"}
