[Ionut] [[BR]]
- Improve ClipPlane management (bunch equations into the matrix shader buffer) [[BR]]
- Immediate mode emulation primitives set their own state based on specified hash instead of relying on state functions to be defined [[BR]]
- updateStates() function is now called right before the actual draw call to facilitate future batching work [[BR]]
- added tracked bool values (similar to those in ShaderInfo) to SGN class to fix selection bug. [[BR]]
— will probably create a “stateTracker” class to allow multiple classes to use tracked variables without all of the code duplication [[BR]]

- Reworked the Camera class[[BR]]
— Now fully quaternion based [[BR]]
— Basic camera types added but not used yet (third person, first person, orbit) [[BR]]
- Cleaned up Material and Texture handling [[BR]]
- Added clipping plane support [[BR]]
— Similar to OpenGL fixed-function clip planes but fully shader driven [[BR]]
— Added a new class, “Plane”, that helps define clip planes [[BR]]
- Optimized the Singleton class to allow faster “getInstance” calls without performance penalties [[BR]]
-- “createInstance” must be called for each singleton class before usage. Or “gerOrCreateInstance” can be used, which is basically the former “getInstance” implementation [[BR]]
- Improved console logging by changing some heap allocations to stack and removing dependencies on the std::string class [[BR]]
- Added a lot of performance optimizations related to coding standards and redundant calculations [[BR]]
— e.g. Frustum AABB check didn’t need to recompute the AABB points as they were calculated already [[BR]]
— e.g. A vector did not need to be set to 0 on initialization as that is already it’s default state on creation [[BR]]
— e.g. Faster Framerate and Timing calculations by using less member variables that are not needed outsied of calling functions [[BR]]
- The SceneState now contains the SceneRenderState and is passed on to the SceneGraph’s update calls [[BR]]
- Better material export/import to/from XML format [[BR]]
- More bug fixes and cleanups [[BR]]
