          Release Notes: Improved support for multi-threaded, multi-pipe applications, including performance improvements. New OpenGL Shading Language based precipitation particle effects that provide high performance and high image quality rendering of rain and snow. A new OpenFlight loader with support for version 16.1, including OpenGL Shading Language support. A new Quake3 BSP loader. The TerraPage loader has been updated to TerraPage 2.2. New outline and drop shadow support for osgText. A range of bugfixes.

          •  21 Dec 2005 21:00

            Release Notes: This release adds support for OpenGL 2.0, including OpenGL Shader Language and a new render to texture framework with support for Frame Buffer Objects and PBuffers. Full API reflection/introspection is supported via the osgIntrospection library. The special effects library osgFX provides a framework for implementing effects with a range of different hardware capabilities. Database paging support allows real-time viewing of massive terrain databases, backed up with osgTerrain, a library for generating whole earth, geo-specific terrain paged databases. Many new examples are available, along with new loaders for 3rd party imagery, video, and 3d database formats.
