OpenSceneGraph-3.3.3

OpenSceneGraph-3.3.3, [/b]released on 19th December 2014, key deliverables in this dev release are:

New osgTerrain::DisplacementMappingTechnique that uses sharing of geometry tiles and height field textures to render the terrain, reducing main memory and GPU memory usage to less than 40% of previous usage, and reduces GPU costs to around 60% of previous requirements for a terrain.
New LAS plugin (depends upon libLAS and Boost)
New GStreamer plugin for cross platform video
New OpenGL extension set-up architecture that reduces both the code footprint, library size and runtime memory footprint, as well as make it easier to extend.
Support for glVertexAttribDivisor via new osg::VertexAttribDivisor StateAttribute
Support for glBlendEquationi, glBendFunci, glColorMaski and glEnable/glDisablei iva new BlendEquationi, BlendFunci, ColorMaski, and Enablei/Disablei StateAttributes to better support Multiple Render Target usage.
New osg::ShaderStorageBufferObject class and osgssbo example.
New osggpucull example that demonstrates culling on the GPU.
Threading safety and performance improvements to the DatabasePager
Refactor of osg::Drawable so that it is no subclassed from osg::Node allow it to be directly placed in the scene graph without the need for a Geode parent.
Standardization of callbacks in Node, Drawable, StateSet and StateAttributes
Improved Android toolchain build
Improvements to QT4 and QT5 support in osgQt
Improvements to the new osgUI NodeKit and Lua Scripting support
