Implementations

impl SpritePipeline

pub(crate) fn new(app: &Application, output_format: TextureFormat) -> Self

pub(crate) fn draw_stage( &self, app: &Application, pass: &mut RenderPass<'_>, stage: &Stage, ) -> (u32, u32)

Traverse stage in pre-order, accumulate sprite instances grouped by (texture id, blend mode), then draw one batch per group.

Returns the number of draw calls emitted and total sprites rendered.

pub(crate) fn draw_subtree( &self, app: &Application, pass: &mut RenderPass<'_>, stage: &Stage, start: NodeId, exclude: &HashSet<NodeId>, ) -> (u32, u32)

Render only the subtree rooted at start. Nodes whose IDs are in exclude (and their descendants) are skipped — used by the auto-dispatch advanced-blend renderer to walk the scene “minus” the advanced-blend subtrees.
