Callback that executes custom rendering logic

Required Methods

fn update( &self, info: PaintCallbackInfo, window_entity: RenderEntity, pipeline_key: EguiPipelineKey, world: &mut World, )

Paint callback will be rendered in near future, all data must be finalized for render step

fn render<'pass>( &self, info: PaintCallbackInfo, render_pass: &mut TrackedRenderPass<'pass>, window_entity: RenderEntity, pipeline_key: EguiPipelineKey, world: &'pass World, )

Paint callback render step

Native wgpu RenderPass can be retrieved from TrackedRenderPass by calling TrackedRenderPass::wgpu_pass.

Provided Methods

fn prepare_render<'w>( &self, info: PaintCallbackInfo, render_context: &mut RenderContext<'w>, window_entity: RenderEntity, pipeline_key: EguiPipelineKey, world: &'w World, )

Paint callback call before render step

Can be used to implement custom render passes or to submit command buffers for execution before egui render pass
