OGRE Changelog

What's new in OGRE 1.9.0

• Core Improvements:
• 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)
• Platform Support:
• Android Port
• Remove eclipse based android port
• CMake based build support
• Create find Ant / NDK packages (currently Ant and the NDK must be in the global path)
• Generate android make files for the sample browser
• Use android tool chain to compile OGRE as static lib
• Cleanup RTSS (Remove OgreStringSerialiser)
• Improve platform integration
• Add Android log listener into OgreRoot
• Disable Filesystem- / Zip- / EmbeddedZip- Archives on android
• Resource system improvements
• OgreAPKFileSystemArchive to handle file access inside the APK
• OgreAPKZipArchive so we can handle zip files inside the APK (APK is also compressed using zip)
• Improve EGL support
• Create concrete subclasses of EGL-Support/Window/Context
• Handle context creation / configs inside OGRE
• Resource recreation / Handle it like DX device lost / restore
• Add managed resource class which every resource derive from (only active on Android - handled via macros)
• Recreation of Texture, Shader, HardwareVertexBuffer
• ETC1 texture codec
• PKM support
• Sample browser
• Add touch input support
• Build a APK file via CMake command line
• Add rotation support
• Fix / Enable more samples
• Compositor not working
• Improve CPU/ vendor detection
• Add how to build it on Linux / OSX / Win32
• Provide pre-compiled dependencies
• Fix our dependencies so the can compile against the android tool chain
• Windows Metro style application (WinRT)
• Add support as a new platform (named WinRT).
• Create a WinRT project for the sample browser.
• Create a how to compile file.
• Get all existing samples to work with the D3D11 render system.
• Multi monitor\device support.
• Windows Phone 8 port.
• OS X
• Add a helper function to get a sandbox friendly temp file name for iOS and OS X.
• Other fixes to file handling in response to App Store rules.
• Support for building with libc++ on OS X.
• Proper example of DisplayLink usage in the SampleBrowser.
• Plugins and components are now built as frameworks.
• Add escape key as a shortcut for Cancel. Fix crash when hitting cancel as well.
• RenderSystems:
• DirectX 11
• Improvements from GSoC project.
• Add tessellation shaders support.
• Add tessellation sample.
• Add dynamic linking support.
• DirectX 9Ex support
• Added OpenGL 3+ RenderSystem. Still marked as experimental and under heavy development.
• OpenGL ES
• GLES 2 terrain support.
• OpenGL ES state and uniform caches.
• Rewrote PVRTC codec, adding cube map, 3D and mipmap support. Only files created with PVRTexTool are supported now, not Apple's texturetool utility.
• Experimental OpenGL ES 3.0 support.
• GL RenderSystem
• GLEW updated to 1.9.0.
• Remove restriction that all GLSL programs have the same matrix order when linking.
• Numerous other bug fixes, documentation fixes and updates and general code improvements.
