Implemented in rt::PointLight.

init()

virtual void rt::Light::init ( Viewer &  )

pure virtual

This method is called by Scene::init() at the beginning of the display in the OpenGL window.

Implemented in rt::PointLight.

light()

virtual void rt::Light::light ( Viewer &  )

pure virtual

This method is called by Scene::light() at each frame to set the lights in the OpenGL window.
