intersectRay3d MethodStatic

Search facets for the first one that intersects the infinite line.

• To process all intersections, callers can supply an options.acceptIntersection callback that always returns false. In this case, intersectRay3d will return undefined, but the callback will be invoked for each intersection.
• Example callback logic:
  • Accept the first found facet that intersects the half-line specified by the ray: return detail.a >= 0.0;
  • Collect all intersections: myIntersections.push(detail.clone()); return false; Then after intersectRay3d returns, sort along ray with myIntersections.sort((d0, d1) => d0.a - d1.a);

intersectRay3d(visitor: PolyfaceVisitor | Polyface, ray: Ray3d, options?: FacetIntersectOptions): undefined | FacetLocationDetail

@returns detail for the (accepted) intersection with detail.IsInsideOrOn === true, or undefined if no (accepted) intersection.

@see intersectRay3d

Returns - undefined | FacetLocationDetail

detail for the (accepted) intersection with detail.IsInsideOrOn === true, or undefined if no (accepted) intersection.
