 //! Meshes are better known for their use in 3D rendering, but we can use them in a 2D context too. Without a third dimension, the meshes we're building are flat – like paper on a table. These are still very useful for "vector-style" graphics, picking behavior, or as a foundation to build off of for where to apply a shader.

-//! A "shape definition" is not a mesh on its own. A circle can be defined with a radius, i.e. [`Circle::new(50.0)`][Circle::new], but rendering tends to happen with meshes built out of triangles. So we need to turn shape descriptions into meshes.

 //! Thankfully, we can add shape primitives directly to [`Assets<Mesh>`] because [`Mesh`] implements [`From`] for shape primitives and [`Assets<T>::add`] can be given any value that can be "turned into" `T`!

-//! "Shape primitives" here are just the mathematical definition of certain shapes, they're not meshes on their own! A sphere with radius `1.0` can be defined with [`Sphere::new(1.0)`][Sphere::new] but all this does is store the radius. So we need to turn these descriptions of shapes into meshes.

 //! While a shape is not a mesh, turning it into one in Bevy is easy. In this example we call [`meshes.add(/* Shape here! */)`][`Assets<A>::add`] on the shape, which works because the [`Assets<A>::add`] method takes anything that can be turned into the asset type it stores. There's an implementation for [`From`] on shape primitives into [`Mesh`], so that will get called internally by [`Assets<A>::add`].
