[Orxonox-commit 4776] r9445 - code/branches/shaders/src/orxonox/graphics

[davidsa at orxonox.net]

Author: davidsa
Date: 2012-11-13 16:54:24 +0100 (Tue, 13 Nov 2012)
New Revision: 9445

Added:
   code/branches/shaders/src/orxonox/graphics/LensFlare.cc
   code/branches/shaders/src/orxonox/graphics/LensFlare.h
Modified:
   code/branches/shaders/src/orxonox/graphics/CMakeLists.txt
Log:
Added orxonox::LensFlare, to add LensFlare effects, this is still very much WIP, still needs more flare components, more configurability and hardware occlusion queries
