Trait to implement to provide tessellation features.

Associated Types

type Tessellation

A type representing tessellation on GPU.

Required Methods

fn new<T>(mode: Mode,
          vertices: &[T],
          indices: Option<&[u32]>)
          -> Self::Tessellation where T: Vertex

Create a Tessellation from its vertices and a Mode.

If indices == None, the vertices represent an array of vertices that are connected to each others in the order they appear. If you want to connect them in another way, you can index them with Some(indices).

fn destroy(tessellation: &mut Self::Tessellation)

Destroy a Tessellation.

fn attributeless(mode: Mode, vert_nb: usize) -> Self::Tessellation

Create a Tessellation that will procedurally generate its vertices (i.e. attribute-less).

You just have to give the Mode to use and the number of vertices the Tessellation must have. You’ll be handed back a Tessellation object that doesn’t actually hold anything. You will have to generate the vertices on the fly in your shaders.
