[Ionut] [[BR]]
-Separated responsibilities between “Application” and “Kernel” [[BR]]
--“Application” handles data such as window dimensions, logs, “ParamHandler” etc [[BR]]
--“Kernel” handles the main loop, SFX, GFX, physics, sceneManager etc updates [[BR]]
---“Kernel” is now a “Core” component [[BR]]
-Reduced coupling between some classes by passing more info via parameters rather than relying on singleton access [[BR]]
--Ex: eyePos in “Terrain”,“Water” and “Trigger” classes is now passed as a "vec3<F32>" on render call rather than querying “CameraManager” [[BR]]
-Reworked “GLWrapper” shutdown routine [[BR]]
Singleton witch hunt [[BR]]
-“Kernel” is no longer a singleton and it’s initialized on application startup in the “Application” class[[BR]]
-“CameraManager” is no longer a singleton and it’s instantiated in the kernel [[BR]]

[Ionut][[BR]]
-First steps in moving away from a generalized “ResourceManager”: [[BR]]
--Added templated resource loaders (Core\Resources\ConcreteLoaders). Just add a new loader for a new resource type and it’s ready for use [[BR]]
---Next step involves moving loading responsibility from the resource itself to the resource loader that handles it’s creation [[BR]]
--Renamed the ResourceManager to ResourceCache and limited it’s responsibility from general resource operations to a more standard abstract template factory with cache [[BR]]
---Manager base class is renamed to BaseCache as it’s a wrapper for a cache map in essence [[BR]]
---Next step involves adding a ResourceCache per scene (dropping Singleton status) with the possibility of sharing resources between them (to avoid reloading existing resources for a new scene) [[BR]]
-Translated AITenisScene and PingPongScene source code to english [[BR]]

[Ionut] [[BR]]
-Fixed animated bounding box calculations[[BR]]
-BoundingBox recalculation per frame is now a general SceneNode property [[BR]]
--Note: Animated BB’s have problems with multi-threaded collision detection for now (see AITenisScene) [[BR]]
-Wrapped boost::mutex to separate file and moved it to shared_mutex structure as read requests are more frequent than write requests [[BR]]
-Mesh class now calls animations update on all of it’s subclasses so animations for each node in a mesh are in sync [[BR]]
-Split up GUI elements by class [[BR]]
-Added base code for a console GUI element (disabled) [[BR]]
-Animations can now be disabled in confg file [[BR]]
-Added a “texture not found” default texture [[BR]]
-Some AI rewrite in AITenisScene (translation to english in next commit) [[BR]]

[Ionut] [[BR]]
Features: [[BR]]
-Added a proper RenderState Management system similar to the D3D default one[[BR]]

--Nodes are sorted by shader first then by state hash depending on current render stage [[BR]]

--Every entity submits it’s desired state before render [[BR]]
--Every state is checked before rendering a VBO or other primitive type[[BR]]
[[BR]]

--Reflections are triggered between pre-render and render calls [[BR]]
--Water now derives from Reflector class as well [[BR]]
[[BR]]

[Ionut] [[BR]]
Features: [[BR]]
-Added a physics system interface instead of direct PhysX interaction to allow other physics engines (Bullet, ODE etc) to be easily implemented [[BR]]
--This will aid in Object-Object collisions and character control in future revisions [[BR]]
-Added an Ogre3D inspired FrameListener which now allows Before-frame/during-frame/after-frame event plugins of callbacks [[BR]]

-RenderQueue now sorts and queue’s translucent and opaque objects separately[[BR]]

-Reduced calls to glEnable[[BR]]
[[BR]]

[ Ionut ] [[BR]]
- Added a PreRenderStage Builder that allows multiple pre-render stages to be added to the pre-render step [[ BR ]]
--A PreRenderStage is composed of a series of PreRender Operators that generate certain PostFX outputs that are used by the PostFX class [[BR]]
--Each PreRenderOperator, similar to a “plugin”, can use any number of input FBO’s, any input shader and render target to generate an effect [[BR]]
--Rendering pipeline has been modified to allow the specification of current render stage [[BR]]
[[BR]]
Added C++<>Shader attribute passing support for shaders[[BR]]
-Added per-pixel fog [[BR]]
-Fixed some typo’s in uniform names [[BR]]
-Optimized shadow generation pipeline [[BR]]
-Added cast/receive shadow options for materials [[BR]]
-FBO’s now clear color and depth buffers when Begin() is called [[BR]]
-Fixed loading of primitives' material properties [[BR]]
-All shaders now use the same shadowmapping techniques [[BR]]
-Quad3D’s can now be modified by specifying a target rect [[BR]]
-Split the “lighting.frag” shader in 3 variants: one that only applies color properties, one with textures and one with bump-mapping [[BR]]
--This reduces fragment shader complexity for the first 2 shaders [[BR]]
--Each material change will now force a shader recalculation for the object [[BR]]
-Renamed sphere’s “size” member to “radius” [[BR]]

[ Ionut ] [[BR]]
-Restructured code base to a more logical layout [[BR]]
--Geometry folder contains shapes, materials, animations and the importer; Environment folder holds sky, terrain, water, vegetation; etc [[BR]]
--All header files are moved to a “Headers” sub-folder [[BR]]
--Renamed most of the Romanian code/comments/files/folders to English [[BR]]
--Added comments to parts of the code (ongoing from now on) [[BR]]
[[BR]]
-Rewrote the entire lighting system [[BR]]
--Added a LightManager class to handle all lights [[BR]]
---LightManager calls updates and render calls to all lights it manages [[BR]]
--Lights have all needed properties stored in 2 maps (one for vector values, one for float values) [[BR]]
--Added a LightImpostor class that takes the light’s properties and applies it to a dummy sphere [[BR]]
--If a light should draw it’s impostor, the impostor draws the dummy sphere [[BR]]
--Rewrote the Light <-> GFXDevice interaction [[BR]]
---Each light stores it’s type in a variable and passes all properties to the rendering API that then decides what to use based on that type [[BR]]
--Each light handles it’s own ShadowMapping [[BR]]
[[BR]]
-ShadowMapping: [[BR]]
-Each light stores it’s own depth maps and generates them based on it’s type [[BR]]
-LightManager binds all available depth maps and shaders pick them up automatically for use [[BR]]
-Each shadow map (of a total of 3 per light) corresponds to a detail level[[BR]]
-The final shadow map resolution is decided by the shadow detail level set in the config [[BR]]
--Camera and Frustum are set up for shadow rendering and applied to the render callback set for the current light (for example, Scene::render()) [[BR]]
--The light manager tells every light that has “_castShadows = true” to generate shadowmaps automatically after the Scene::PreRender stage [[BR]]
--ShadowMaps are blurred before applied to the fragment’s final color via shaders. [[BR]]
[[BR]]
-Added detail level configuration options [[BR]]
--ToDo: add shaders for each detail level [[BR]]
[[BR]]
-Moved all predefined geometry from immediate mode to VBO’s [[BR]]

[[BR]]
-Fixed GuiElement visibility toggle [[BR]]
-Fixed GuiText color state problem [[BR]]
-Added FBO texture format options [[BR]]
-VBO rendering uses U16 as default instead of U32 (better for GPU) [[BR]]
