Module render 

Renderer — pipeline cache, draw-call batcher, filter pass orchestrator.

Evolution: M0.5: hardcoded triangle. M0.6: textured-quad path (render_quad). M0.9: sprite batcher with scene-graph traversal (render_stage). M0.16: filter pass orchestrator.

Modules

advanced_blend 🔒

Advanced (Tier C) blend modes — implemented as offscreen filter passes that sample backdrop + foreground and run a per-mode blend function in the fragment shader.

batcher

Draw-call batcher — groups Sprites with the same texture + blend mode.

blend_pipeline 🔒

BlendPipelineMap — pre-built RenderPipeline per standard blend mode.

blit 🔒

Fullscreen-sampler “blit” pipeline — copy a RenderTexture onto an arbitrary target view.

clip 🔒

Clip pipeline — apply a MaskShape to a foreground RenderTexture and write the masked result.

flex_text_pipeline 🔒

Late-pass textured-quad pipeline for FlexText scene nodes.

graphics_pipeline 🔒

Graphics primitive pipeline.

mask_cache 🔒

Cache of generated mask textures (M-DYN.2 / AUT-44).

mask_combine

Boolean operations on alpha-mask textures (M-VEC.11 / AUT-63).

mask_compose 🔒

Compose a foreground RenderTexture against a separately- generated alpha mask texture (M-VEC.4..6 / AUT-56..58).

mask_texture 🔒

Generate an alpha-mask RenderTexture from a MaskShape (M-DYN.1 / AUT-43).

mesh_pipeline 🔒

Mesh pipeline — perspective-rotated textured quad (M0.19).

pass

Filter pass orchestrator — ping-pong RenderTextures across N filter passes.

path_clip 🔒

Path clip pipeline — rasterize a closed-polygon mask for a foreground RT (M-MASK / AUT-35 freehand path mask).

path_mask_texture 🔒

Generate an alpha-mask RenderTexture from a closed polygon (M-DYN.1 / AUT-43, freehand-path variant).

pipeline

wgpu::RenderPipeline cache, keyed by shader + blend mode + format.

quad_pipeline 🔒

Textured-quad pipeline.

scene_walk 🔒

Shared scene traversal + transform helpers (M-TEXT.0 / AUT-74).

sprite_pipeline 🔒

Instanced sprite pipeline — M0.9.

text_pipeline 🔒

Bitmap text pipeline — M0.15.

triangle_pipeline 🔒

Hardcoded triangle pipeline — M0.5 hello-triangle.

Structs

RenderStats

Frame statistics returned by Renderer::render_stage.

Renderer

2D renderer.

Functions

collect_dispatched_nodes 🔒

Pre-order walk that returns every visible node which needs the slow-path dispatch — either:
