Equalizer is a programming interface and resource management system for scalable multipipe applications.An Equalizer application can run unmodified on any visualization system, from a singlepipe workstation to large scale graphics clusters and shared memory visualization systems. Equalizer is build from ground up as a parallel, scalable programming interface solving the problems common to any multipipe application.Equalizer development started in 2005. The source code is available for interested developers and early adopters. Equalizer is a cross-platform toolkit and is initially available for Linux and Mac OS X. A Windows version is planned. Please contact us if you are interested to learn more about Equalizer, to participate in the design and development, or if you have any other questions.What's New in This Release: [ read full changelog ]New Features:· Subpixel compounds for full-scene anti-aliasing (FSAA) or depth-of-field (DOF) decomposition· Data distribution and data updates using reliable UDP multicast· Support for writing applications which are not using OpenGLEnhancements:· Support for Mac OS X 10.6 Snow Leopard· Tile and range boundaries for the load equalizer· New eq::util::Accum class for accumulation operations using an FBO or the OpenGL accumulation buffer· Multiple windows on the same pipe can join the same software swap barrier· Configurable message pumpOptimizations:· Configurable object serialization buffer size· Performance optimization for image compression· Reduce memory footprint for eq::net::Objects with change type DELTAExamples:· EqPly: added anti-aliasing when the application is idle· EqPly: recursively search directories for models· EqPly: switch to faster VBO rendering on OSXAPI Changes:The following changes breaking compatibility with Equalizer 0.6 source code were made:· The utility classes Accum, AccumBufferObject, FrameBufferObject and Texture where moved from the eq to the eq::util namespace.· eq::Window::getColorType has been changed to getColorFormat for consistency.· The font handling provided by eq::Window has been refactored for non-OpenGL rendering support.Documentation:The following documentation has been added or substantially improved since the last release:· The Programming and User Guide has been extended to 91 pages and 53 figures.· The Accumulation Buffer Object API has been added to the Programming Guide.· The Subpixel compound provides FSAA and DOF decomposition· Multicast Data TransferBug Fixes:Equalizer 0.9.1 includes various bugfixes over the 0.9 release, including the following:· 2873353: Usage of ext/hash_map and -Werror causes compiler error· 2834063: eqPly and eVolve freezes on Mac with glX· 2828269: eVolve depth compositing is broken· 2642034: Win32: max 64 connections possible· 2874188: Lockup at shutdownKnown Bugs:· The following bugs were known at release time.
