bidi-shaper/dist/adapters/three.d.ts

Logical→visual Unicode BiDi (UAX #9) reordering + Arabic contextual shaping for renderers outside the browser (PDF, canvas, WebGL, SVG, terminals, games). Zero dependencies.

import { D as Direction, R as RenderOptions } from '../render-BhplWt64.js';

/**
 * three.js adapter (`bidi-shaper/three`).
 *
 * TextGeometry, BitmapText implementations, and most SDF/MSDF text plugins
 * place glyphs in string order with no shaping. Feed them
 * {@link prepareText} output instead of the raw string.
 *
 * For multi-line labels use {@link prepareLines}: each line carries its
 * resolved direction so you can set the anchor/pivot per line
 * (e.g. troika-text `anchorX`, or aligning geometry bounding boxes).
