`mod viewport`¶

module viewport¶

Structs and Unions

struct Viewport¶

A viewport, which holds all uniform buffers unique to a viewport, such as the ViewportProjection-spec.

Will bind to group 1.

Implementations

Functions

fn bind(&self, render_pass: &mut RenderPass<'_>)¶: Binds this Viewport to group 1

fn bind_group_layout(&self) -> &BindGroupLayout¶: The bind group layout for this Viewport

fn new(projection: ViewportProjection, device: &Device) -> Self¶: Creates a new viewport. Allocates uniform buffers in a bind group.

fn update(&mut self, updater: &mut impl BufferUpdater, projection: ViewportProjection)¶: Updates this Viewport

struct ViewportProjection¶

The specs/data of a viewport

Will map coordinates from source into target

Can be converted into a projection-matrix using Into<Mat4>.

Implementations

Functions

fn identity() -> Self¶: An identity-ViewportProjection. Transforms nothing and fills the whole viewport.

struct ViewportSource¶

The source-coordinates of the viewport. Will be from (x, y) in the top-left to (width, height) in the bottom-right.

Implementations

Functions

fn bottom(&self) -> f32¶: The bottom edge (maximum y) of this ViewportSource

fn from_point_size(from: (f32, f32), size: (f32, f32)) -> Self¶: Creates a ViewportSource from a given start-point and size.

fn from_tl_br(tl: (f32, f32), br: (f32, f32)) -> Self¶: Creates a ViewportSource from a given top-left and bottom-right point

fn right(&self) -> f32¶: The right edge (maximum x) of this ViewportSource

struct ViewportTarget¶

The target coordinates of the viewport. Coordinates are in wgpu coordinate-space.
