Detailed Description

Lightsource.

Warning:

Very incomplete

Bug:

Poor id and enable/disable management

Todo:

Destructors

Lights are used to lit objects in Scene. At the moment this class implements a simple OpenGL light wrapper with minimum featurs.

Light is positional by default unless set to directional by setType

Definition at line 58 of file Light.h.
