<h2 id="details">Detailed Description</h2>
<p>The 3d ray is defined by its origin, direction and length. It will be affected by the transformations applied to the entity it belongs to.</p>
<p>Ray casting tests will be performed every frame as long as the component is enabled. The hits property will be updated with the list of intersections.</p>
