====== Vector3 ======

Vector3 also supports the same access methods as [[2d_vector|Vector2]], with an additional ''z'' component.

==== Construction methods ====

Vector3 objects can be constructed by either:
  * Supplying the ''x, y, z'' components as floats.
  * Supplying nothing, defaulting to a zero vector.

<note tip>
If you need a unit Vector3, you can use the static ''Vector3::ZERO'', ''Vector3::UNIT_X'', and similar instead of creating new objects initialized to those values. 
</note>

==== Utility functions ====
  * ''Dot''
  * ''Magnitude''
  * ''MagnitudeFast'', which omits the slower square root function call.
  * ''Distance''
  * ''Cross'', which can either return a new Vector3 or apply to the current one depending on the arguments.
  * ''Angle''
  * ''Project'', always returns a new object, taking the ''length'' and ''direction'' as Vector3 objects
  * ''Perpendicular'', always returns a new object, taking the ''length'' and ''direction'' as Vector3 objects
  * ''Reflection'', always return a new object, taking an existing Vector3 and a normal as Vector3 objects.

Note that the typical !=, ==, *= operators are all implemented for this class.
