A vector pointing in the direction the ray goes. Default is *0, 0, 0*.
</div>
<h3>.[page:Number near]</h3>
<div>
Defines the closest distance that will be checked for intersections, starting from origin. Default is *0*.
</div>
<h3>.[page:Number far]</h3>
<div>
Defines the furthest distance that will be checked for intersections, starting from origin. Default is *Infinity*.
</div>
<div>Hence, intersections will only be checked in the range *(near, far)*.</div>
<h2>Methods</h2>
<h3>.setPrecision( [page:Float value] )</h3>
<div>Defines the maximum precision used when determining intersections. This is specially important when checking collisions between almost parallel objects, and can make the difference between reporting a collision or not.</div>
<div>Determines whether the ray intersects *object*. The result is an array containing tuples of the form</div>
<code>
{
distance: // distance between the origin and the intersected object,
point: // exact point where the intersection occurs,
face: // exact face that the ray intersected,
object: // the intersected object
}
</code>
<div>Note that even if we're checking only an object against a ray, the ray can intersect the object in more than one point. Hence, the return value is an array and not a single tuple.</div>
<div>Goes through the *objects* array, and determine whether they ray intersects them. The result is an array that contains similar tuples to the ones returned by intersectObject</div>
The entries in the returned array are sorted by ascending distance (i.e. closest objects first).
