`bevy_curvo` is a helper library for rendering curves and surfaces modeled with [Curvo](https://github.com/mattatz/curvo) directly within the [Bevy](https://github.com/bevyengine/bevy) environment.
[Demo](https://github.com/mattatz/bevy_curvo/assets/1085910/5a6864c5-85fa-44ee-b194-23aaa8ff452a)
*You can try the demo on web. https://mattatz.github.io/bevy_curvo/*
## Usage
```rust
// Create a set of points to interpolate
let points = vec![
Point3::new(-1.0, -1.0, 0.),
Point3::new(1.0, -1.0, 0.),
Point3::new(1.0, 1.0, 0.),
Point3::new(-1.0, 1.0, 0.),
];
// Create a NURBS curve that interpolates the given points with degree 3
let interpolated = NurbsCurve3D::::try_interpolate(&points, 3, None, None).unwrap();
// Create a NURBS surface by extruding the curve along the z-axis
let extrusion = NurbsSurface::extrude(&interpolated, Vector3::z() * 3.0);
// Create a SurfaceTessellation from the NURBS surface
let tess = extrusion.tessellate(Some(AdaptiveTessellationOptions {
norm_tolerance: 1e-2 * 2.5,
..Default::default()
}));
// Create a bevy friendly data from the tessellation
let surface_mesh = NurbsSurfaceMesh::from(tess);
commands.spawn(PbrBundle {
// Here you can use the mesh to render the surface
mesh: surface_mesh,
material: materials.add(StandardMaterial {
..default()
}),
..default()
});
// or you can build a mesh for the surface
let tri: Mesh = surface_mesh.build_surface_triangle_list(Some(RenderAssetUsages::default()));
```
## Run the example
```sh
cargo run --example scene --features=examples
```
or with [cargo-make](https://github.com/sagiegurari/cargo-make)
```sh
cargo make example
```
## Run the example in the browser
By using [cargo-make](https://github.com/sagiegurari/cargo-make), wasm files are generated using wasm-bindgen-cli, and web applications are served using an http server.
```sh
cargo make serve
```
