34	Shadows	bensch	dave	"Shadows are one of main issues when it comes to realism, without it the scene just looks wierd. Shadows are in real-time computer grafics what the neutrons are in Atoms, it is the glue, the one thing that tells us, that the scene we see really interacts.

In orxonox so I think we need the following approach:

  * __Idea__: 
   * Shadows from Objects to the ground plane.
   * Shadows via SUB Textures
  * __Interface__:
   * Takes one or more terrains, to project the Shadow to
   * Takes a list of World-entities, for shadow calculation
   * Renders the Textures placed onto the Plane
  * __Extensions__:
   * Soft Shadows
   * (Shadow-Volumes (this is relly hard, and I do not think we need it))
   * etc.
  * __Resources__:
