Struct luminance::tess::Tess

pub struct Tess { /* fields omitted */ }

GPU tessellation.

Methods

impl Tess

fn new<'a, V, T>(mode: Mode, vertices: V, indices: Option<&[u32]>) -> Self where TessVertices<'a, T>: From<V>, T: 'a + Vertex

Create a new tessellation.

The mode argument gives the type of the primitives and how to interpret the vertices and indices slices. If indices is set to None, the tessellation will use the vertices as-is.

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

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.

fn as_slice<T>(&self) -> Result<BufferSlice<T>, TessMapError> where T: Vertex

Get an immutable slice over the vertices stored on GPU.

fn as_slice_mut<T>(&mut self) -> Result<BufferSliceMut<T>, TessMapError> where T: Vertex

Get a mutable slice over the vertices stored on GPU.

Trait Implementations

impl Drop for Tess

fn drop(&mut self)

A method called when the value goes out of scope.
