I am proud to announce the long-awaited 0.9.4 release of the Vision Egg
available now from the website at <http://www.visionegg.org/>. A large
number of features have been added. This is a major improvement on the
last release, and I recommend all users upgrade.
This release features:
Complete electrophysiology application (see below)
Luminance and color calibration possible
Constant visual angle (perspective-distorted) grating stimulus added
Constant visual angle (perspective-distorted) gaussian and circular
windows added
3D texture-mapped sphere stimulus added
Random dot stimulus added
Texture module re-written for ease-of-use, clarity, and support of
dynamic texture updating
Color grating stimulus added
Support for plaids added
Masks for gratings and textures implemented using multitexturing - uses
high bit depth available on some hardware
Vision Egg Programmer's Manual created
GLTrace module for tracking all calls to OpenGL
Many more minor features and bug fixes
New electrophysiology application features:
Complete application with ready-to-run experiments
Application extendible with new experiments by modifying example
experiments
Full-screen graphics possible with "server" application, GUI client
controls experiments over TCP
Automated sequence control, including sequences-of-sequences
Stimulus onset timing calibration / verification support
3D position / perspective-distortion calibration support
Parameters saved during experiments as Python or Matlab scripts
Complete configurations can be saved and restored from file
All code written for the 0.9.3 release should continue to run on the
0.9.4 release. There may be some slight changes in functionality due
to bug fixes.
Over the coming weeks, I will be updating the website to reflect these
changes. If you like the Vision Egg, tell your colleagues! I envision
a few bugfix/minor feature releases before releasing version 1.0 and
declaring the Vision Egg to be out of beta testing.
