    **Glass material**

Main parameters:

    * Diffuse color set to black
    * Reflection color set to white
    * Transmission color set to white
    * Fresnel enabled
    * Double sided
    * IOR set to 1.55

This setup uses ``RED::IMaterial::SetupRealisticMaterial`` to produce a glass material. The setup relies on energy preservation and Fresnel to balance the energy between reflection and transmission. A glass material has no diffuse term, is transparent and fully reflective. Fresnel then does the job. The IOR may be changed depending on the kind of transparent glass looking surface to simulate.
