- <div class="desc">
- This class makes raycasting easier. Raycasting is used for picking and more.
-
- </div>
- <h2>Constructor</h2>
- <h3>[name]( [page:Vector3 origin], [page:Vector3 direction], [page:Float near], [page:Float far] ) {</h3>
- <div>
- [page:Vector3 origin] — The origin vector where the ray casts from.<br />
- [page:Vector3 direction] — The direction vector that gives direction to the ray.<br />
- [page:Float near] — All results returned are further away then near. Near can't be negative. Default value is 0.<br />
- [page:Float far] — All results returned are closer then far. Far can't be lower then near . Default value is Infinity.
- </div>
- <div>
- This creates a new raycaster object.<br />
- </div>
- <h2>Properties</h2>
- <h3>.[page:Ray ray]</h3>
- <div>
- The Ray used for the raycasting.
- </div>
- <h3>.[page:float near]</h3>
- <div>
- The near factor of the raycaster. This value indicates which objects can be discarded based on the distance.<br />
- This value shouldn't be negative and should be smaller than the far property.
- </div>
- <h3>.[page:float far]</h3>
- <div>
- The far factor of the raycaster. This value indicates which objects can be discarded based on the distance.<br />
- This value shouldn't be negative and should be larger than the near property.
- </div>
- <h3>.[page:float precision]</h3>
- <div>
- The precision factor of the raycaster.
- </div>
- <h2>Methods</h2>
- <h3>.set( [page:Vector3 origin], [page:Vector3 direction] )</h3>
- <div>
- [page:Vector3 origin] — The origin vector where the ray casts from.<br />
- [page:Vector3 direction] — The direction vector that gives direction to the ray.
- </div>
- <div>
- Updates the ray with a new origin and direction.
- </div>
- <h3>.intersectObject( [page:Object3D object], [page:Boolean recursive] )</h3>
- <div>
- [page:Object3D object] — The object to check for intersection with the ray.<br />
- [page:Boolean recursive] — If set, it also checks all descendants. Otherwise it only checks intersecton with the object.
- </div>
- <div>
- checks all intersection between the ray and the object with or without the descendants. Intersections are returned sorted by distance, closest first.
- <code>
- [ { distance, point, face, faceIndex, object }, ... ]
- </code>
- </div>
- <h3>.intersectObjects( [page:Array objects], [page:Boolean recursive] )</h3>
- <div>
- [page:Array objects] — The objects to check for intersection with the ray.<br />
- [page:Boolean recursive] — If set, it also checks all descendants of the objects. Otherwise it only checks intersecton with the objects.
- </div>
- <div>
- checks all intersection between the ray and the objects with or without the descendants. Intersections are returned sorted by distance, closest first.
- <code>
- [ { distance, point, face, faceIndex, object }, ... ]
- </code>
