Crate dotloom_render 

dotloom-render

The default Dotloom renderer, built on wgpu. It consumes the public scene contract (dotloom_scene) and never reads documents, so it can be replaced.

• Lines are instanced, screen-constant-width capsules with analytic anti-aliasing and screen-space dash patterns.
• Fills are tessellated with lyon; MSAA smooths their edges when available.
• Text uses a signed-distance-field atlas of a bundled OFL font (Inter subset with Latin, Turkish, Greek, Cyrillic and technical symbols).
• Items are batched into order-preserving chunks with world bounding boxes for viewport culling; meshes are cached per item and rebuilt only when the item changes, its zoom bucket changes (curves), or the glyph atlas is reset.
• Only WebGL2-compatible GPU features are used, so the WebGPU and WebGL2 backends run identical shaders.

The browser binding lives in dotloom-render-web; native offscreen rendering (PNG) is behind the png feature.

Modules

color

Colors and themes.

overlay

Grid and interaction overlays (built every frame; cheap and view-dependent).

tess

CPU tessellation of scene items into GPU-ready meshes.

text

Text: font loading, signed-distance-field glyph atlas and layout.

view

Camera and coordinate conversions.

Structs

ChunkBuffers

GPU buffers of one chunk (or transient mesh).

FrameStats

Statistics of the last frame.

Renderer

The wgpu renderer. Consumes scene deltas; owns only derived GPU/CPU caches.

RendererOptions

Renderer options.

SceneCache

Scene state held by the renderer.

Enums

RenderError

Renderer errors.

Constants

CHUNK_ITEMS

Maximum items per chunk.

MAX_CHUNK_EXTENT

Maximum world extent of a chunk (keeps f32 offsets precise to ~8 µm).
