Changeset 2350 for code/branches/objecthierarchy2/src/orxonox/objects

Timestamp:

Dec 7, 2008, 4:18:11 AM (16 years ago)

Author:

Message:

• Added support for postprocessing shaders (bloom, motion blur, …). Shaders are only visible if Plugin_CgProgramManager is included in bin/Plugins.cfg.

• Added class GlobalShader which is visible on all clients and can be activated or deactivated by triggers or other events.

• Added RadialBlur shader to the SpaceShip's engine. The strength of the RadialBlur depends on the SpaceShip's velocity.
