Struct OwnedPath 

pub struct OwnedPath<'r> { /* private fields */ }

Rendering path for applications that own the window loop and wgpu encoder.

Obtained from ViewportRenderer::owned. The renderer encodes all GPU work and returns a wgpu::CommandBuffer for the caller to submit.

Use this with winit, raw wgpu, or any setup where you control the encoder.

Implementations

impl<'r> OwnedPath<'r>

pub fn render( &mut self, device: &Device, queue: &Queue, output_view: &TextureView, frame: &FrameData, ) -> CommandBuffer

Render a single viewport. Runs prepare internally and returns a command buffer to submit.

pub fn prepare_scene( &mut self, device: &Device, queue: &Queue, frame: &FrameData, scene_effects: &SceneEffects<'_>, ) -> ScenePreparedToken

Multi-viewport: upload scene-level GPU data shared across all viewports.

Call once per frame before any prepare_viewport or render_viewport calls. Returns a [ScenePreparedToken] that must be passed to each prepare_viewport call in the same frame. The token may be borrowed multiple times for multi-viewport scenes.

pub fn prepare_viewport( &mut self, device: &Device, queue: &Queue, _token: &ScenePreparedToken, id: ViewportId, frame: &FrameData, )

Multi-viewport: upload per-viewport GPU data for id.

Call after prepare_scene and before render_viewport. The _token parameter is a borrow of the [ScenePreparedToken] returned by prepare_scene; it enforces that prepare_scene has been called earlier in the same frame.

pub fn render_viewport( &mut self, device: &Device, queue: &Queue, output_view: &TextureView, id: ViewportId, frame: &FrameData, ) -> CommandBuffer

Multi-viewport: encode draw calls for id into its own command buffer. Call after prepare_scene and prepare_viewport for this id.
