== Introduction ==

~~Intro~~The sounrce of light in a 3D world can be one of many types. These types are limited to Ambient (a light source from all directions) and Diffuse (Light cast from one point in a direction).

== Tag Attributes ==

* number

** '''Usage:''' <light number="3" />.

** OpenGL handles many different lights at the same time and therefore requires an identifier to access them.

** This number is restricted from 1 to 10.

* type

** '''Usage:''' <light type="diffuse" />.

** This attributes specifies the type of light that will be created and the way it can be used.

** The attribute only accepts the values of 'ambient' and 'diffuse'.

* color

** '''Usage:''' <light color="#FF00FF" />.

** This determines the color of the light that is eing cast on the object. This values should be in Hex format.

* position

** '''Usage:''' <light position="0.3, 0.6, 2.1" />.** The ''position'' attribute specifies the 3D location of the light source.** Three values must be specified as a 3D vector separated by commas.* orientation** '''Usage:''' <light orientation="4.1, 6.3, -2.8" />.** The ''orientation'' defines the direction the light source is pointing at. ** This attribute only applies to Diffuse Lighting and is ignored if used in another case.** The default is {0.0, 0.0, 1.0} if ommited.

== Syntax ==

<pre>
