What's new in Equalizer 1.0 Beta:

March 1st, 2011

· Major stability improvements were made over 1.0-alpha, delivering the full feature set and API of Equalizer 1.0 for stable application development.

What's new in Equalizer 0.9.1:

February 5th, 2010

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 OpenGL

Enhancements:

· 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

Optimizations:

· Configurable object serialization buffer size
· Performance optimization for image compression
· Reduce memory footprint for eq::net::Objects with change type DELTA

Examples:

· EqPly: added anti-aliasing when the application is idle
· EqPly: recursively search directories for models
· EqPly: switch to faster VBO rendering on OSX

API 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 Transfer
