Detailed Description

Implements the sun in the scene together with shadow mapping techniques.

Author

Felix

The Sun is a derivation of the Light class which is itself a SceneObject. In addition to the methods from SceneObject, a Sun has methods that use different shadow mapping techniques. The method drawOmni supports Omnidirectional Shadow mapping where every SceneObject is rendered into a cubemap texture. This texture will then be used for the shadow map lookup. In addition, we implemented Shadow volumes and therefore 2 renderpasses are used. The method ambientPass and SVPass compute the shadow volumes using each SceneObject in the 2 seperate renderpasses. For each seperate renderpass, effectobjects are used that are passed onwards to the individual SceneObjects that will be rendered. Framebuffer Objects are used for storing different shadow textures.
