OpenSceneGraph-3.3.3

OpenSceneGraph-3.3.3版本发布,引入了地形渲染新技术、LAS插件、GStreamer视频插件等关键功能,同时对OpenGL扩展架构、OpenGL Shader Storage Buffer Object类、多目标渲染使用状态属性等进行了改进,显著提高了内存和GPU使用效率,减少了成本。

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
  • Bug and build fixes
