API Reference > geometry-core > CartesianGeometry > EllipsoidPatch > intersectRay intersectRay Method Return intersections of the ray and surface. uv values in the intersections are in radians unless convertIntersectionRadiansToFractions is true requesting conversion to patch fractions. intersectRay(ray: Ray3d, restrictToPatch: boolean, convertIntersectionRadiansToFractions: boolean = false): CurveAndSurfaceLocationDetail[] Parameter Type Description ray Ray3d restrictToPatch boolean convertIntersectionRadiansToFractions boolean Returns - CurveAndSurfaceLocationDetail[] Defined in core/geometry/src/geometry3d/Ellipsoid.ts Line 829 Last Updated: 13 June, 2024
