Struct nannou::ui::backend::glium::Vertex

pub struct Vertex {
    pub mode: u32,
    pub position: [f32; 2],
    pub tex_coords: [f32; 2],
    pub color: [f32; 4],
}

The Vertex type passed to the vertex shader.

Fields

mode: u32

The mode with which the Vertex will be drawn within the fragment shader.

0 for rendering text. 1 for rendering an image. 2 for rendering non-textured 2D geometry.

If any other value is given, the fragment shader will not output any color.

position: [f32; 2]

The position of the vertex within vector space.

[-1.0, -1.0] is the leftmost, bottom position of the display. [1.0, 1.0] is the rightmost, top position of the display.

tex_coords: [f32; 2]

The coordinates of the texture used by this Vertex.

[0.0, 0.0] is the leftmost, bottom position of the texture. [1.0, 1.0] is the rightmost, top position of the texture.

color: [f32; 4]

A color associated with the Vertex.

The way that the color is used depends on the mode.

Trait Implementations

impl Clone for Vertex

fn clone(&self) -> Vertex

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Vertex

fn fmt(&self, f: &mut Formatter) -> Result<(), Error>

Formats the value using the given formatter.

impl Vertex for Vertex

fn build_bindings( ) -> Cow<'static, [(Cow<'static, str>, usize, AttributeType, bool)]>

Builds the VertexFormat representing the layout of this element.

fn is_supported<C>(caps: &C) -> bool where     C: CapabilitiesSource + ?Sized,

Returns true if the backend supports this vertex format.
