Struct EguiWgpuRenderer 

pub struct EguiWgpuRenderer { /* private fields */ }

Custom wgpu renderer for egui primitives.

Implementations

impl EguiWgpuRenderer

pub fn new(surface_format: TextureFormat) -> Self

Creates a new, uninitialized renderer.

pub fn initialize(&mut self, device: &Device, shader_source: &str)

Initializes the render pipeline and bind group layouts.

Must be called once with the wgpu device before any rendering.

pub fn update_textures( &mut self, device: &Device, queue: &Queue, textures_delta: &TexturesDelta, )

Updates textures from egui’s [TexturesDelta].

pub fn register_external_texture( &mut self, device: &Device, view: &TextureView, ) -> TextureId

Registers an externally-created wgpu texture view (e.g. an offscreen viewport render target) as an egui-managed texture.

Returns the [TextureId] that can be used in egui Image widgets.

pub fn update_external_texture( &mut self, device: &Device, id: TextureId, view: &TextureView, )

Updates the wgpu texture view backing an existing external texture.

Call this when the offscreen render target is resized.

pub fn render( &self, state: &mut EguiRenderState<'_>, clipped_primitives: &[ClippedPrimitive], pixels_per_point: f32, )

Renders the egui output.
