====== Shader Library ======

//provided by the plugin ShaderLibrary//

A set of predefined shaders of often used materials(including soild, leafs or greenhouse parts). 
Shaders are provided in as [[01_user_documentation:05_object:02_light:12_shaders:04_ggx|]],[[01_user_documentation:05_object:02_light:12_shaders:05_ward|]] and [[01_user_documentation:05_object:02_light:12_shaders:02_phong|]]. They are also categorized into RGBA and spectral shaders.

===== Functionalities =====


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

  * __apply__: apply on a selected 3d object
  * __add__: adds it to the [[01_user_documentation:03_interacting_with_groimp:02_panels:02_explorers:10_shaders| shader explorer]]
  *   * __Shaders__: open the [[01_user_documentation:03_interacting_with_groimp:02_panels:02_explorers:10_shaders| shader explorer]]


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

It is possible to create the shader directly from rgg code without any GUI interaction using this command: 
<code java>
shaderLib("spectral/phong/polished_metal")
</code>

For example in the construction of a module:

<code java>
module A(float len) extends Sphere(0.1)
 {
 	{setShader(shaderLib("spectral/phong/polished_metal"));}
 }
</code>
