intersectRay3d MethodStatic
Search facets for the first one that intersects the infinite line.
- To process all intersections, callers can supply an
options.acceptIntersectioncallback that always returns false. In this case,intersectRay3dwill 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 afterintersectRay3dreturns, sort alongraywithmyIntersections.sort((d0, d1) => d0.a - d1.a);
- Accept the first found facet that intersects the half-line specified by the ray:
intersectRay3d(visitor: Polyface | PolyfaceVisitor, ray: Ray3d, options?: FacetIntersectOptions): undefined | FacetLocationDetail
| Parameter | Type | Description |
|---|---|---|
| visitor | Polyface | PolyfaceVisitor | facet iterator |
| ray | Ray3d | infinite line parameterized as a ray. The returned detail.a is the intersection parameter on the ray, e.g., zero at ray.origin and increasing in ray.direction. |
| options | FacetIntersectOptions | options for computing and populating an intersection detail, and an optional callback for accepting one |
Returns - undefined | FacetLocationDetail
detail for the (accepted) intersection with detail.IsInsideOrOn === true, or undefined if no (accepted) intersection
