OGRE 3D 1.9正式版发布，SDK会稍后放出。主要更新内容如下：
OgreMain
Extract the overlays from OgreMain and transform it into a own overlay component
Progressive Mesh improvements and new Mesh LOD sample.
Loads of documentation updates
Added Mesh::mergeAdjacentTexcoords to collapse two adjacent texcoords into one (i.e. float2 texcoord0 & float2 texcoord1 become float4 texcoord0)
According to the documentation, the default SceneManager ambient light should be black, which is wasn't though.
SceneManager: updateSceneGraph should happen BEFORE prepareShadowTextures.
AtomicScalar operators should be returning their value. Only affects using GCC or Clang.
New class ProgressiveMeshGenerator to degenerate mesh detail at runtime.
Bug fix for Sphere::merge. Inaccurate results can occur if one sphere does not fully encompass the other.
New LOD strategies 'distance_box' and 'screen_ratio_pixel_count'. Details, see Ogre Manual.
SharedPtr moved to use atomics (related API change see below in the porting notes).
SubMesh has a new method: clone(const String& newName, Mesh *parentMesh) to perform deep copies of SubMesh objects. The second parameter is optional and can be used to reparent a SubMesh.
Removed Configfile::load(const String& filename, const String& resourceGroup, const String& separators, bool trimWhitespace) because it can easily be ambiguous. If you wish to load from a resource group, use the existing function loadFromResourceSystem. The arguments are identical to the removed function. See OGRE-175.
New Volume Rendering component with LOD. See GSoC 2012 Volume Rendering
Many Terrain improvements.See GSoC 2012 Terrain Improvements
RTSS
Changed error handling of RTSS sub-render state parameter creation. Sub-render state now throws exception on errors
Added 2 new demo samples: multiple lights and textured fog
CgProgramManager
Added support for high-level output profiles glslv/glslf/glslg and hlslv/hlslf (glslg not fully working yet)
