Implementations

impl GraphicsTree

pub fn new() -> GraphicsTree

Creates a new graphics tree.

pub fn is_empty(&self) -> bool

Returns true if graphics tree is empty.

pub fn clear(&mut self)

Clears all graphics.

pub fn draw<F, T, G>(&self, texture_buffer: &mut TextureBuffer<F, T>, g: &mut G)

where T: ImageSize + CreateTexture<F>, G: Graphics<Texture = T>,

Draws graphics to backend.

Trait Implementations

impl Graphics for GraphicsTree

type Texture = Texture

The texture type associated with the back-end.

fn clear_color(&mut self, color: Color)

Clears background with a color.

fn clear_stencil(&mut self, value: u8)

Clears stencil buffer with a value, usually 0.

fn tri_list<F>(&mut self, draw_state: &DrawState, color: &Color, f: F)

where F: FnMut(&mut dyn FnMut(&[[f32; 2]])),

Renders list of 2d triangles using a solid color.

fn tri_list_c<F>(&mut self, draw_state: &DrawState, f: F)

where F: FnMut(&mut dyn FnMut(&[[f32; 2]], &[[f32; 4]])),

Same as tri_list, but with individual vertex colors.
