Material

The appearence of virtual objects, the appearance of the surface, is defined by its material and the lighting in the scene. The material is a set of parameters that define the way to represent the geometry surface.

Basic colors and transparency

The basic color parameters are:

• diffuse, essentially the basic color of the material (RGB from 0.0 to 1.0)
• ambient, a color offset not changed by lighting
• specular, the color of specular reflections on a surface
• emissive, TODO
• transparency, a single value from 0.0 (fully transparent) to 1.0 (fully opaque)
