Raycaster

Note: This documentation is for the old 0.1.0 version of A-Frame. Check out the documentation for the current 1.5.0 version

The raycaster component defines the functionality for an entity to do intersection testing with a raycaster. By itself, this component does not do anything, but it can be and is used by components such as the cursor. The raycaster component will poll for intersections with other entities and set this.intersectedEl to the closest intersected entity.

Since it can be useful for other components but inherently does not add behavior, we will instead document the properties of the raycaster component prototype below.

Property	Description
intersectedEl	The entity currently intersecting the raycaster.
raycaster	three.js raycaster object.
