Lamina

Note

Early work-in-progress. APIs and visuals will change. Fine for sibling apps (Terra, Visage); not a polished published toolkit yet.

Lamina is a reusable wgpu immediate-mode UI toolkit (not egui) and design system, shared by Terra (landscapes) and Visage (face / character animation).

It is domain-neutral: no terrain or character types, no product chrome. Apps own the window and event loop. Typical frame: 3D (or other) pass first, then GuiRenderer::render with LoadOp::Load, then a single present.

Stack

• wgpu 24 — Lamina draws into the app’s existing surface
• No winit — the host owns input and the event loop (Terra/Visage use winit 0.30)
• No domain types — widgets and layout only; products keep their own crates
• Timeline / graph — timeline_ruler, playhead, track_row, key_marker, curve_graph, record_button (domain-neutral; Visage composes them)

Crate	Role
lamina	Immediate-mode wgpu UI toolkit and design system
lamina-test-gpu	Headless GPU harness for GUI tests (dev-only)

Depend via path

Terra and Visage live as siblings under GameDevTooling and path-depend on this crate:

lamina = { path = "../Lamina/crates/lamina" }

Pin wgpu 24 to match this crate.

Build

cargo test -p lamina
cargo check -p lamina

GPU tests skip when no adapter is available.
