threepipe/src/core/geometry/EllipseCurve3D.ts

A modern 3D viewer framework built on top of three.js, written in TypeScript, designed to make creating high-quality, modular, and extensible 3D experiences on the web simple and enjoyable.

/**
 * A 3D version of three.js EllipseCurve that returns Vector3 points.
 * Useful for creating circular/elliptical 3D paths for TubeGeometry and TubeShapeGeometry.
 *
 * Note: EllipseCurve extends Curve<Vector2>, but this override returns Vector3 at runtime.
 * Type casts may be needed when passing to APIs expecting Curve<Vector3>.
