Confidential Professional Support
Bespoke development
Consultancy
Training
Community support and contributions:
The diverse and growing community of over 5000 developers is centred around the public osg-users mailing list/forum, where members discuss how best to use OpenSceneGraph, provide mutual support, and coordinate development of new features and bug fixes. Members of this community come from many different countries with backgrounds ranging from some of the world's largest aerospace companies, game companies, and visual simulation specialists to university researchers, students and hobbyists.
The OpenSceneGraph project owes a great deal to the community for its development and support, in particular we wish to thank the 569 individuals from around the world that have directly contributed to the development and refinement of the OpenSceneGraph code base.
OpenSceneGraph 3.4 release introduces shader composition, new osgUI library, displacement mapping, volume rendering, lua scripting support and much more
PERTHSHIRE, Scotland - 12th August 2015 - OpenSceneGraph Professional Services announces the release of OpenSceneGraph 3.4, the industry's leading open-source scene graph technology, designed to accelerate application development and improve 3D graphics performance. OpenSceneGraph 3.4 written entirely in Standard C++ and built upon OpenGL, offers developers working in the visual simulation, game development, virtual reality, scientific visualization and modeling markets - a real-time visualization tool which eclipses commercial scene graph toolkits in functionality, stability and performance. OpenSceneGraph 3.4 runs on all Microsoft Windows platforms, Apple OS/X, IOS, GNU/Linux, Android, IRIX, Solaris, HP-UX, AIX and FreeBSD operating systems.
Updates include:
* New #pragma(tic) composition shader functionality built into the core OSG that provides a easy to use yet flexible scheme for controlling and composing shaders at runtime levering GLSL support for #define and #pragma.
* New osgTerrain::DisplacementMappingTechnique to uses vertex, geometry and fragment shader based displacement mapping technique that dramatically lowers the CPU and GPU memory footprint and bandwidth needs for the same visual quality. The new scheme enables paged terrain that work robustly on smaller hardware, or with far higher loads without framedrops. This new technique levels #pragma(tic) shader composition to enable one to toggle on/off features in the shaders at runtime in a way that is as convenient to use as toggle modes in a fixed function pipeline scene graph.
* New osgVolume::MultipassTechique that uses multipass rendering and shaders to enable seamless mixing of traditional 3D geometry and volumes, support for geometry hulls that constrain where the volume should be rendered as well as improving the ray tracing shaders so that they are both faster and have higher visual quality than the previous generation of ray traced shaders supported by OSG-3.2 releases and before.
* New osgDB::Classiterface class that provides an easy to use mechanism for introspection of scene graph classes, allowing one to get, set properties and invoke methods in a generic way, making the task of integrating 3rd prarty tools such as scripting languages straight forward.
* New Lua scripting support via a plugin that integrates Lua 5.2.3 and the OSG via the OSG's native serialization codes.
* New osgUI NodeKit, that enables User Interface elements to be placed directly into 3D scene graph. The classes are fully scriptable so you create create UI and behaviours all within lua scripts.
* Improvements to OpenGL ES 1.1, ES 2.0 and ES3.0 support, including platform specific extensions
* Improvements to OpenGL 4.x support with a range of new extensions support
* Updates to osgQt to support Qt5 and provide better support for Qt4

The theme for the 2.0 release has been making the [=OpenSceneGraph=] easier to use, yet more flexible and powerful.
Features include:
* New unified build system using [[http://www.cmake.org CMake]], which simplifies the build process, automatically detecting installed dependencies and providing build configuration as well as support for a wide range of development tools.
* New libraries:
** osgViewer - provides native windowing support and viewer functionality that scales from a single view embedded in a window to multi-thread, multi-gpu, multi-screen viewers and can handle multiple scene graphs at one time. The new viewer architecture also provides support for novel display systems that require distortion correction, such as hemispheres and full domes as well as power-walls and caves. It replaces Producer as a windowing toolkit.
** osgManipulator - provides a set of interactive manipulators for scaling, rotating and moving objects in the scene.
** osgShadow - provides an extensible framework for adding dynamic shadows to your scene.
* New low-level extensible intersection framework that includes support for line, plane and polytope intersections.
* New high-level intersection classes that support paged databases, [=LineOfSight=], [=HeightAboveTerrain=] and [=ElevationSlice=].
* View-dependent overlay - provides ability to overlay text, country boundaries etc. directly on to terrain, even paged databases.
* Plugins
** Improvements to the [=OpenFlight=], COLLADA, [=AC3D=], DDS plugins and many more
** New TXF texture font reader.
** New [=VRML2=] reader (using the [=OpenVRML=] library).
* Easier 3rd party windowing integration
** With examples showing integration with GLUT, SDL, Qt, [=WxWidgets=] and MFC
* External dependencies removed simplifying build and distribution
** [=OpenThreads=] is moved into the core of [=OpenSceneGraph=] and is no longer an external dependency
** Thanks to the integration of windowing support in osgViewer, [=Producer=] is no longer a dependency.

!!![=OpenSceneGraph=] 1.2 release introduces Windows 64bit and AIX support, COLLADA support, processor affinity and texture atlas builder.
PERTHSHIRE, Scotland - 12th September 2006 - [=OpenSceneGraph=] Professional Services announces the release of [=OpenSceneGraph=] 1.2, the industry's leading open source scene graph technology, designed to accelerate application development and improve 3D graphics performance. [=OpenSceneGraph=] 1.2, written entirely in Standard C++ and built upon [=OpenGL=], offers developers working in the visual simulation, game development, virtual reality, scientific visualization and modeling markets a real time visualization tool which rivals established commercial scene graph toolkits in functionality and performance. [=OpenSceneGraph=] 1.2 runs on all Microsoft Windows platforms, Apple OS/X, GNU/Linux, IRIX, Solaris, HP-UX, AIX and [=FreeBSD=] operating systems.
The [=OpenSceneGraph=]-1.2 release introduces:
* Support for Windows 64 bit build, allowing Windows programmers to take advantage of greater scalability previously only available to [=OpenSceneGraph=] users under Linux, IRIX, Solaris, [=FreeBSD=] and OSX.
* Support for IBM's AIX operating system, bringing the total number of supported operating systems to 8.
* COLLADA plugin support for both the reading and writing of COLLADA 1.4 .dae files. COLLADA is the new industry standard data asset exchange format that is now supported by a range of 3D modelling packages and provides a unified art path route to and from the [=OpenSceneGraph=].
* Processor affinity support allowing application to lock cull-draw and database processes to specific processors, thereby avoiding cache coherancy problems associated with processes moving from processor to processor.
* A Texture Atlas builder has been added to the database optimization classes, allowing either manual or automated setting up of texture atlas. Using texture atlas can improve performance by reducing the number of state changes required to render a scene, and by allowing databases to batched in large groups of geometry, in a form that better suits modern graphics arhitectures.
* GPU timing stats have been added to the viewer class, provided the time taken to process allow drawing operations down on the GPU for the previous frame. Coupled with the existing timing of CPU update, cull and draw dispatch the stats reporting now provides the end user with a clearer idea of whether their application is CPU or GPU limited and server as a better guide to performance optimization work.
* A range of bug fixes and API refinements.
The [=OpenSceneGraph=]-1.2 release is the culmination of 7 years development, with contributions from 208 developers from around the world. The user base is composed of a wide range of industry and academic users with over 1400 developers subscribed to the projects public support mailing list.

BETA releases
25th May 2005 - OpenSceneGraph-0.9.9
>>> OpenGL Shading Language integrated into core, Introspection, movies, particle effects and much more...
Introduction to the OpenSceneGraph:
The OpenSceneGraph is an Open Source, high performance real-time graphics toolkit, written for developers of vis-sim applications, virtual reality, scientific visualisation, education through to games. The toolkit is based on OpenGL and Standard C++ and most portable toolkit of its kind, supporting Windows, Linux, OSX, Irix, Solaris, FreeBSD and HP-UX and Aix, including 64 bit support on Windows, Linux, OSX, Irix and Solaris. OpenGL version from 1.1 through to 2.0 are all seemlessly supported, including many of the latest extensions. The OpenSceneGraph is now firmly established as one of the worlds most popular scene graph technologies, and is used and developed by community of over a thousand developers.
The OpenSceneGraph 0.9.9 release:
The latest release of the OpenSceneGraph, 0.9.9, is the culmination of 7 years development and is the final milestone before reaching 1.0. All core features for 1.0 are now in place and ready for deployment. Since the development driven is by technical convergence rather than usual marketing forces, even the beta releases of the OpenSceneGraph are already mature enough for major industry players to have adopted it for their own application development, with many companies already releasing products based on top of the OpenSceneGraph.
The 0.9.9 release includes many minor API refinements, bug fixes and optimizations, but also major new features including tight integration of OpenGL Shading Language support directly into the core osg library, new reflection/introspection support, new particle effects, movie support and DXF import. Details follow:
OpenGL Shader Language support:
OpenGL Shading Language (GLSL) support has been moved from the osgGL2 node kit directly into the core osg library. This move also involved refactoring the handling of state so that it now specifically supports GLSL Program, Shaders and Uniforms in a convenient and flexible way. State sorting and lazy state updating are now applied to both Program and Uniforms to maximize performance throughput. The work was spearheaded by 3Dlabs engineer Mike Weiblen, collaborating with Robert Osfield with contributions from the community.
Introspection support:
The new osgIntrospection and associated library wrappers provides support for full API reflection/introspection. That facilitates integration of the OpenSceneGraph with other programming languages, development of generic editors of scene graph attributes, general purpose serialization of scene graph objects such as for reading and writing to disk, or across local networks to support systems such as graphics clusters. The osgIntrospection is designed
to be non-intrusive, allowing 3rd Party libraries to be wrapped without these libraries needing to have explicit introspection support added into them. The-non intrusive approach also keeps introspection support a separate module which only needs to be loaded if you require it, this leaves the core libraries light-weight and focused on the their particular tasks. osgIntrospection is the inspired work of Marco Jez. Thanks also go to ANU Viz Lab for graciously funding Robert Osfield's contribution to this sub-project.
Better support for Apple native Windowing:
Thanks to new support for AGL and CGL in OpenProducer, all OpenSceneGraph/osgProducer-based examples and application will run straight out of the box under OSX native AGL or CGL Windowing. This allows better integration of OpenSceneGraph applications with OSX, access to faster and up to date OpenGL drivers.
Support for latest OpenGL extensions:
Support for the Non power of two texture feature of OpenGL 2.0 has been added
to all the core texture classes. Also to facilate high resolution video streaming, OpenGL Pixel Buffer Objects are now supported. Support for blend equation and logic op have also been added.
Terrain generation and rendering enhancements:
The osgTerrain library, for generating whole earth, geospecific paged databases, has been enhanced with support for alpha source textures and multiple texture layers. The new multiple texture layers support can be controlled at runtime via the new osgFX::osgFX MultiTextureControl node, which provides a convenient means for blending between the different layers at run-time. Multiple textures layers can be very useful for mixing topographical maps with satellite/aerial photography.
Particle Effects:
To make it easier to add particle effects to your application a new osgParticle::ParticleEffects node has been written, with five concrete implementations of SmokeEffect, FireEffect, ExplosionEffect and ExplosionDebrisEffect which you can create, adjust and add to your scene graphs.
DXF and Movie plugins:
A new DXF plugin has been added for reading .dxf files. Movie support has also been enhanced with integration of the OpenSceneGraph with Xine-lib via the xine plugin, this allows you to add movie content into your applications, including DVD's and streamed across the LAN, thanks to Xine-libs inbuilt streaming support.
Application and examples:
To facilitate faster builds and a logical division between applications that come with the OpenSceneGraph, the original example directory has now been split into two, with the new applications/ directory now comprising osgviewer, osgconv, osgarchive, osgversion and osgdem. The Makefiles now build by default only the applications directory, thus avoiding the cost of recompiling the 74 example programs. Examples can still be compiled by run make COMPILE_EXAMPLES=yes, or setting COMPILE_EXAMPLE=yes as an env var or in a custom dependencies file.
There are eight new examples, osgblendequation and osglogicop demonstrate the new osg::BlendEquation and osg::LogicOp state attributes, osgGLUTkeyboardmouse and osgGLUTsimple are GLUT based examples, osgslice does some image reading of rendered slices, osgparticleeffects demonstrates the new osgParticle::ParticleEffects.
osgpbuffer also example now uses Producer's pbuffer support making it portable across platforms and much cleaner.
API refinements, bug fixes and performance improvements:
There have been many bug fixes, a number of performance improvements and API cleanups that have occurred throughout the 0.9.8 - 0.9.9, too many separate items to enumerate here. Together with the above new features they all go to making the OpenSceneGraph-0.9.9 the most robust, high performance and feature rich version so far, and sets the stage for the upcoming 1.0.
We would like to thank the following engineers for their contributions in the 0.9.8 - 0.9.9.9 time frame (in alphabetic order):

26th November 2004 - OpenSceneGraph-0.9.8
>>> Support for database archives, improved pager, 3d compressed textures
Release 0.9.8 reflects a continuation of the prior commitment to release
often, arriving only two short months after 0.9.7. This contrasts sharply
to the long period between 0.9.6-2 and 0.9.7. The following set of
improvements and features are part of the 0.9.8 release.
The osgDB Pager has been Improved to provide better multi-processor
stability and constant frame rate peformance.
Reference documentation has been taken out of the main distribution and
placed on the public website. The documentation is also now completely
built with Doxygen.

from a web site through an http interface.
o OSGA - This plugin provides database archival support, including
large file (greater than 2 GB) support.
o OBJ - The existing obj plugin has been re-written for clean up.
New support for 3d texture compression using the
GL_NV_texture_compression_vtc extension has been added, providing an
improvement on the S3TC compression techniques.
The OSG Spelling Bee is making its mark in this release, with submissions
by the community to correct spelling and typo errors throughout the osg,
osgDB and osgUtil libraries.
osgDB::ReaderWriter and osgDB::Registry have been refactored to allow
multi-threading of database reading and writing.

Fixes to osg::Image::flipVertical() adding support for mipmaps and
compressed textures.
DDS plugin now can vertically flip images by using "dds_flip" Options string.
Added support in osgTerrain for reading imagery with color tables.
9th August 2004 - OpenSceneGraph-0.9.7
>>> support for and generation of large scale geospatial databases,
>>> support for movies and examples of shadows and volume rendering.
The 0.9.7 encompasses many improvements, bug fixes, new examples and
significant new functionality, the most notable of which is a new
osgTerrain library for generation of large scale geospatial databases.
The new osgTerrain library and associated osgdem utility program
allows users to use moziacs of geospatial imagery and digital elevation
maps to generate a complete paged database which can be used with
standard OSG viewers, and users programs. By utilising GDAL to load the
imagery and DEM's a wide range of geospatial formats are supported.
The TerraPage plugin has also been rewritten ontop of the OSG's
osg::PagedLOD and osgDB::DatabasePager which provides support for the
tile fallback mechanism to ensure that no holes or cracks appear in the
databases being roamed, and to achieve constant frame rate via load
balancing mechanisms with osgDB::DatabasePager.
The osgDB::DatabasePager has been further improved to provide more
configurable load balancing which allows application developers to achieve
constant frame rates when using paged databases.
Double Vec & Matrix classes & CoordinateSystemNode/EllipsoidModel class
have been introduced to better support browsing of large scale databases,
and to provide a mechanism for tracking the local up orientation when
roaming whole earth databases.
osgUtil has been enhanced with:
- an improved triangle tipper class (osgUtil::TriStipVisitor),
- a new simplifier (osgUtil::Simplifer) for reducing triangle density of
osg::Geometry leaves (utilised by osgTerrain to provide simplification
of terrain tiles),
- improved and more configurable optimizer (osgUtil::Optimizer),
- a new utility class for compiling and releasing OpenGL objects
(osgUtil::GLObjectVisitor) replaces the previous and more limited
DisplayListVisitor.
All the osgGA::MatrxManipulator's (used for camera manipulator etc) have
been revamped with usage of doubles internally, and with tracking of the
current CoordinateSystem if one is active, to be better support whole
earth databases. All the MatrixManipulators have been extend to allow
the setting of a user defined home position. Two new manipulators have
been introduced osgGA::TerrainManipulator, for roaming whole earth/terrain
databases, and osgGA::TrackerManipulator which allows the camera to be
attached to a node in the scene graph.
Movie support under Linux and OSX via libMpeg3 and Quicktime respectively,
which extend the new osg::ImageStream base class which allows application
developers access to playing, pausing and rewinding movies.
The conversion utility osgconv has been extended to allow compression of
textures and mipmap generation during conversion when writing to the native
.ive binary format. Texture compression and pre computer mipmaps enable
faster loading of databases and lower utilisation of memory resources.
Write support added to JPG plugin.
Write + 3D texture support added to DDS plugin.
Pseudo loaders .trans, .rot and .scale have been added.
Updated LWO, AC3D, BMP, IVE and FLT loaders.
osg::TexGenNode has been added to provide a mechanism for positioning
OpenGL's texture coordinate generation planes.
Fourteen new examples have been added:
osgdem a utility for creating large scale geospatial paged
database
osgphotoalbum an example of how to use PagedLOD to dynamic generate
geometry for paged in imagery
osgbluemarble an example of how to build PagedLOD database for
paging imagery
osgtessellate an example of how to use osgUtil::Tesselate to
tessellate polygonal boundaries
osgsimulation an example of how to use various features in osgSim.
osgdepthshadow an example of how to implement shadows use depth
shadow textures.
osgsimplifier an example of how to use the new osgUtil::Simplifier.
osgspacewarp an example of how to create a special effect that
depends upon tracking the modelview matrix.
osgdistortion an example of how to use prerendering of a texture to
create a distortion effect.
osgsimple a bare bones example of how to create a simple viewer
using a Windowing toolkit, in this example using
Producer, but is written so the example could easily
be modified to work with other Windowing toolkit.
osgkeyboardmouse adding to keyboard and mouse functionality on the
osgsimple base.
osgsimplepager adding database paging support to the osgsimple
example.
osgmovie an example which creates a quad to render a loaded
movie file with - requires the LibMpeg3 (Linux) or
Quicktime (OSX) plugin to work.
osgvolume an example that reads a stack of 2d images to create
a 3D texture, and creates a scene graph using
standard OSG components (osg::ClipNode,
osg::TexGenNode, osg::Billboard and
osg::TexEnvCombine) to create a per per lit volume.
Wrapping up the complete 0.9.7 release is a wide range of smaller features
enhancement and many bug fixes.
2nd October 2003 - OpenSceneGraph-0.9.6-2
>>> osgFX Special Effects nodekit (for bumping mapping & cartoon effects etc), support for double Matrix traversals,
>>> improved build support, thread safety and robustness.
The new osgFX nodekit, written by Marco Jez, adds a set of decorator
nodes that add can be conveniently added above subgraphs in your scene
to add special a range of special rendering effects. Effects include
AnisotopicLight, BumpMapping, Scribe, Specular Highlights and Cartoon
rendering.
Support for double Matrices has been added with the new Matrixd class,
and complimented by the a Matrixf class. The original Matrix class is
now a typedef which can be set to either Matrixf or Matrixd (which is
now the default), When the Matrix typedef is set to Matrixd and the OSG and
dependent apps are recompiled all internal operations such a cull traversals
will now be double with double matrices which much improved numerical
precision, making it ideal for datasets where a large values are contained
with transforms in the scene graph (such as with whole earth databases),
and when a transforms are nested which creates requires concatenation of
a number of matrices to get the final model view matrices.
The osgGA::MatrixManipulators (which are used to control the camera
position) and osgProducer/OpenProducer have been moved across to using
exclusively double Matrices. This has been done to improve numerical
precision when computing camera positions, whilst having little impact
on performance since camera operations are only done a small number of
times per frame.
osg::Quat now supports doubles by default, but also allows users to select
float version osg::Quat simply by changing the osg::Quat::value_type typedef.
Work has been on OpenThreads and OpenProducer, in particular to improve
thread safety and robustness on the Win32 platform. Reported crashes
on exit from osgProducer::Viewer based apps, and freezes during runtime
have been fixed.
Threading problems which caused crashes in recent updates of the Terrapage
loader have also been fixed, and additional internal changes have been made
to improve the Terrapage loader's ability to hit constant frame rates.
Support has also been added for loading light points directly from the
Terrapage database.
A new .iv/.wrl loader plugin, written by Vivek Rajan, at Magic Earth,
has been added to the distribution which uses with OpenInventor or Coin
to load model, converting them into OSG equivalents. Coin has support
for VRML97 models, so can be used to import such models into the OSG.
Since the new plugin is dependent on OpenInventor or Coin the compilation
is optional, but off by default. To compile this plugin under Unix, set
the environmental variable USE_INVENTOR or USE_COIN and recompile.
Windows .dsp project file does to current exist, but should be
possible to add this.
The .ive plugin has been improved with the addition of support for
osgSim light points, and various internal refinements to make it function
better on the various platforms supported by the OSG. Note, these changes
mean that the .ive format has has changed and is no longer compatible
with previous version of .ive. It is recommend that one recreates .ive
for the original source via osgconv or similar to ensure consistency.
A JPEG2000 image plugin has added, written by Michael Gronager. The new jp2
plugin uses the japser open source project to read and write JPEG2000 files.
A scalar bar, and sphere segment helper classes have been added to osgSim,
the new osgscalarbar and osgspheresegment examples demonstrate how to use
these new features.
To help handle running applications of graphics cards/drivers that exhibit
bugs with certain OpenGL extensions, support has been added to the GLextensions
code to allow extensions to be disabled via the new
osg::setGLExtensionDisableString(std::string) function or by setting an
OSG_GL_EXTENSION_DISABLE environmental variables. Follows is an example of
the disable string:
set OSG_GL_EXTENSION_DISABLE =
"ATI:GL_SGIS_generate_mipmap;Sun:GL_EXT_texture_filter_anisotropic:"
New examples include:
osgforest - an example which demonstrates simple techniques for creating forests
osgfxbrowser - an example which demonstrates the various osgFX Effects available
osgscalabar - an example of how to set up the osgSim::ScalarBar.
osgspheresegment - an example of how to set up the osgSim::SphereSegement
osgpagelod - a very simply test program for setting up osg::PagedLOD/osgDB::DatabasePager
23rd July 2003 - OpenSceneGraph-0.9.5
>>> Support added for OpenGL2.0 shaders, native multi-threaded Database paging,
>>> high peformance binary format reading and writing, .dds compressed image
