Struct bevy_egui::render_systems::EguiTransform

pub struct EguiTransform {
    pub scale: Vec2,
    pub translation: Vec2,
}

Scale and translation for rendering Egui shapes. Is needed to transform Egui coordinates from the screen space with the center at (0, 0) to the normalised viewport space.

Fields

scale: Vec2

Is affected by window size and EguiSettings::scale_factor.

translation: Vec2

Normally equals Vec2::new(-1.0, 1.0).

Implementations

impl EguiTransform

pub fn from_window_size(window_size: WindowSize, scale_factor: f32) -> Self

Calculates the transform from window size and scale factor.

Trait Implementations

impl CreateFrom for EguiTransform

where Self: ShaderType<ExtraMetadata = StructMetadata<2usize>>, for<'__, '__> Vec2: CreateFrom,

fn create_from<B: BufferRef>(reader: &mut Reader<B>) -> Self

impl Default for EguiTransform

fn default() -> EguiTransform

Returns the “default value” for a type.

impl ReadFrom for EguiTransform

where Self: ShaderType<ExtraMetadata = StructMetadata<2usize>>, for<'__, '__> Vec2: ReadFrom,

fn read_from<B: BufferRef>(&mut self, reader: &mut Reader<B>)

impl ShaderSize for EguiTransform

where Vec2: ShaderSize,

const SHADER_SIZE: NonZero<u64> = _

Represents WGSL Size (equivalent to ShaderType::min_size)

impl ShaderType for EguiTransform

where Vec2: ShaderType + ShaderSize,

fn size(&self) -> NonZeroU64

Returns the size of Self at runtime

fn min_size() -> NonZero<u64>

Represents the minimum size of Self (equivalent to GPUBufferBindingLayout.minBindingSize)

fn assert_uniform_compat()
