Car Paint

Introduction

The car paint material shader simulates the physical properties of most types of car paint. For computer graphics, car paint is generally modeled as three separate layers:

1. Base pigment layer, with a diffuse color that can change depending on the viewing angle.
2. Metallic, reflective flakes that are embedded within the pigment layer.
3. A 'binder', which is a shiny/waxed coating exhibiting very glossy reflection.

The car paint material shader also exhibits a strong Fresnel effect, which can be controlled by the parameters below and helps with the paint's character. As with the Architectural shader, the Fresnel effect determines what the color should be when viewed at grazing angles.
