====== Light Distribution ======

//provided by the plugin LightLibrary//

A set of predefined light distribution to use in Physical Light. 

{{ :01_user_documentation:03_interacting_with_groimp:02_panels:19_assets_libraries:lightdistribution.png?direct&400 |}}


====== Functionalities ======

From the panel it is possible to use the following functions on a selected distribution: 

  * __add as light source__: to add as a light source to the [[01_user_documentation:03_interacting_with_groimp:02_panels:02_explorers:17_lightsources|]]
  *  __add to scene__: to create a lightNode with a physical light with selected distribution as input and add it to the current scene
  * __apply__: apply on a selected object if possible (if the object is a light Node, or a light source). If the current light source of this object is spectral the new one will be used as light input on the spectral Light
  * __Light Sources__: open the Light explorer


====== in RGG ======

To use this IES through RGG code a set of functions can be used:

to get a LightDistribution:
<code java>
iesLib("LED Floodlight (wide)") 
</code>
to get a PhysicalLight object:

<code java>
physicalLightLib("LED Floodlight (wide)") 
</code>

to get a SpectralLight with a PhysicalLight as a source (see Spectral library).

<code java>
spectralPhysicalLightLib("High-PressureSodium(HPS)","LED Floodlight (wide)") 
</code>


A simple working example could be:

<code java>
protected void init ()
[
 Axiom ==> LightNode().(setLight(physicalLightLib("LED Floodlight (wide)")));
]
