Class Name: Emissive Color

Superclass - SEDRIS Abstract Base

Definition

Intensity component of a Primitive Color, used to simulate light emitted by the object. Since the Emissive Color component is due to light emitted by the object, it is independent of any light sources in the environment, so it is

• independent of the angle of the lit object to the light source
• independent of the angle of the lit object to the observer

FAQs

Does SEDRIS use the OpenGL lighting model?

No, although the terminology is similar. SEDRIS handles transparency somewhat differently than OpenGL does, among other things. For a description of the OpenGL lighting model, see Woo et. al., Chapter 5 "Lighting" of OpenGL Programming Guide, 3rd ed., Addison-Wesley 1999.
