@lunaterra/elements

Reusable drawable elements for Luna-Terra scenes.

Install

pnpm add @lunaterra/elements

Highlights

• Line, text, rectangle, grid, and engineering-dimension primitives.
• Time controls and marker-capable line rendering.
• Designed to compose with @lunaterra/core scene APIs.

Dimension lines

DimensionLine draws a measurement at any angle with conventional extension lines, adaptive open arrows, and a screen-readable label. When the measured gap cannot fit its label, arrowPlacement: 'auto' changes from arrows between the witnesses to inward-pointing arrows outside them:

const sag = new DimensionLine({
  start: new V2(0, 4.6),
  end: new V2(0, 5.3),
  offset: -2,
  label: '0.7 m',
  labelAlongOffset: -0.5,
});
engine.add(sag);
