Struct pixel_widgets::draw::Vertex

#[repr(packed)]
pub struct Vertex {
    pub pos: [f32; 2],
    pub uv: [f32; 2],
    pub color: [f32; 4],
    pub mode: f32,
}

The Vertex type passed to the vertex shader.

Fields

pos: [f32; 2]

The position of the vertex within device coordinates. [-1.0, -1.0] is the left top position of the display.

uv: [f32; 2]

The coordinates of the texture used by this Vertex. [0.0, 0.0] is the left top position of the texture.

color: [f32; 4]

A color associated with the Vertex. The color is multiplied by the end result of the fragment shader. When mode is not 1, the default value is white ([1.0; 4])

mode: f32

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

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

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