Welcome to Equalizer 0.5.1, a framework for the development and deployment of parallel, scalable OpenGL applications. Equalizer 0.5.1 adds a statistics overlay and support for the Paracomp compositing library.
Equalizer 0.5.1 is a developer release, representing a stable snapshot of the
development tree after the 0.5 release. Equalizer 0.5.1 can be retrieved
using:
svn co https://equalizer.svn.sourceforge.net/svnroot/equalizer/tags/release-0.5.1
Features
Equalizer provides the following major features to facilitate the development and deployment of scalable OpenGL applications. A detailed feature list can be found on the Equalizer website.
- Runtime Configurability: An Equalizer application can run on any configuration, from laptops to large scale visualization clusters, without recompilation. The runtime configuration is externalized from the application to a systemwide resource server.
- Runtime Scalability: An Equalizer application can use multiple CPU's, GPU's and computers to scale the rendering performance of a single view.
- Distributed Execution: Equalizer applications can be written to support cluster-based execution. The task of distributing the application data is facilitated by support for versioned, distributed objects.
- Support for Stereo and Immersive Environments: Equalizer supports both active and passive stereo rendering, as well as the head tracking, which is required for immersive Virtual Reality installations.
New in this release
The following features, bug fixes and documentation changes where introduced since the 0.5 release:

- Support for using Paracomp as a compositing backend, see README.paracomp
- Network-based instead of file-based model distribution in eqPly
- Support for the window swapsync hint on WGL
Performance Improvements
- Alpha-blending support in the CPU-based compositor
- Improved performance when using non-threaded pipes

Documentation
The Programming Guide is part of the Equalizer and can be found online. Equalizer does not yet have an Users Guide. The shipped examples provides a reference for developing or porting applications. The Developer Documentation on the website provides further design documents for specific features. The source code is a last resort for information.
