Expand description

Backend execution interface for individual render pass kinds.

Required Methods§

Source

fn ensure_surface( &mut self, id: SurfaceId, desc: &SurfaceDesc, ) -> WavyteResult<()>

Ensure backing storage exists for the declared render surface.

Source

fn exec_scene( &mut self, pass: &ScenePass, assets: &PreparedAssetStore, ) -> WavyteResult<()>

Execute one scene pass that draws source assets into a target surface.

Source

fn exec_offscreen( &mut self, pass: &OffscreenPass, assets: &PreparedAssetStore, ) -> WavyteResult<()>

Execute one offscreen effect pass.

Source

fn exec_composite( &mut self, pass: &CompositePass, assets: &PreparedAssetStore, ) -> WavyteResult<()>

Execute one composite pass that combines intermediate surfaces.

Source

fn readback_rgba8( &mut self, surface: SurfaceId, plan: &RenderPlan, assets: &PreparedAssetStore, ) -> WavyteResult<FrameRGBA>

Read back final frame pixels from surface.
