Struct polystrip::Frame

pub struct Frame<'a, T: RenderDrop<'a>> { /* fields omitted */ }

A frame to be drawn to. The frame gets presented on drop.

Implementations

impl<'a, T: RenderDrop<'a>> Frame<'a, T>

pub fn new(
    context: Rc<Renderer>,
    frame_idx: usize,
    resources: T,
    viewport: Viewport
) -> Frame<'a, T>

pub fn set_global_transform(&mut self, matrix: Matrix4)

Sets the global transform matrix for draw calls after this method call.

If this method is called multiple times, draw calls will use the matrix provided most recently.

Draw calls made before this method call use the identity matrix as the global transform matrix.

pub fn draw_stroked(
    &mut self,
    shape: StrokedShape<'_>,
    obj_transforms: &[Matrix4]
)

Draws a StrokedShape. The shape will be drawn in front of any shapes drawn before it.

pub fn draw_colored(
    &mut self,
    shape: ColoredShape<'_>,
    obj_transforms: &[Matrix4]
)

Draws a ColoredShape. The shape will be drawn in front of any shapes drawn before it.

pub fn draw_textured(
    &mut self,
    shape: TexturedShape<'_>,
    texture: &'a Texture,
    obj_transforms: &[Matrix4]
)

Draws a TexturedShape. The shape will be drawn in front of any shapes drawn before it.

pub fn pixel(&self, x: i32, y: i32) -> Vector2

Converts pixel coordinates to Gpu coordinates
