Intersection
Intersection samples show different cases of intersection detection:
Multiple Async Requests sample demonstrates detection of intersections with all objects in the world using a combination of World::getIntersection() and Landscape::getIntersection() methods. 900 rays from a moving emitter-objects are used. You can check out latency values (number of frames per each result).

Simple Async Request sample demonstrates detection of intersections with all objects in the world using a combination of World::getIntersection() and Landscape::getIntersection() methods. A single ray from the mouse cursor position is used. A normal at the point of intersection is rendered and latency value is displayed.
