cables is under heavy development.
There might be one or another bug, please let us know about it!

There is a newer version of this op!

This version will not receive any updates. It is recommended to use a newer version.

Current version: Ops.Gl.Phong.PhongMaterial_v5

A shaded material for lighting objects

summary (oneliner)

This is probably the most classic material of them all.

It works stand-alone or in conjunction with the light ops.

The op features 2 different diffuse color models, standard Lambert & Oren-Nayar.
Furthermore, there is a dropdown menu for 4 different specular models:
Blinn-Phong, Schlick, Phong, Gauss.

It also has Fresnel capabilities & physical energy conservation of light (if desired).
