Release: https://github.com/Psychtoolbox-3/Psychtoolbox-3/tree/PTB_Beta-2016-09-10_V3.0.13

New features and improvements:

  • Initial hybrid graphics laptop support for Linux (prime renderoffload) “help HybridGraphics”. Describes setup to get the majority of hybrid graphics laptops to work between “useable” and “really well” under Linux.

  • PsychLinuxConfiguration: Automate setup of AMD deep color support, e.g., for DisplayPort deep color and HDMI deep color.

  • Some improvements to XOrgConfCreator.

  • Provide basic compatibility with the Windows-10 “Windows subsystem for Linux”. With a X-Server like XMing installed, allows to run some basic “PTB for Linux” functionality in Windows-10’s new Linux emulation layer. However, no sound, no PsychHID functionality/KeyboardQueus/DAQ, very bad timing, visual tearing artifacts. This more for geek cred than for any even remotely research grade use.

  • New demo VideoIPWebcamCaptureDemo.m - Capture streaming video from Android IPWebcam app.

  • GetGamePadIndices: Make as capable as GetKeyboardIndices.

  • CreateProceduralGabor: Add optional ‘validModulationRange’ parameter. Suggested by Taylor Hanayik.

  • DownloadLegacyPsychtoolbox: It’s dead, Jim! Download of legacy toolbox versions < 3.0.10 is currently broken.

  • SeparateAlphaTextureShader.vert.txt: Add additional (dx2,dy2) offsets. This allows for off-center rotation of sampled texture images. A usage example would be the one described in PTB forum message 20926. Shaders are created via MakeTextureDrawShader(‘SeparateAlphaChannel’), cfe. DriftDemo6.m

  • KbWait: reorganized and simplified input checking a bit. KbQueueFlush minor improvements. From Diederick.

  • KbQueueWait now gained forWhat and untilTime, like KbWait. From Diederick.

  • DrawFormattedText’s ‘flipVertical’ fixed for new text renderer. From Diederick.

  • PsychPortaudio: Give better error feedback if trying to open same device multiple times.

  • Daq: Update help texts wrt. USB 1024-LS. Now verified to work well.

  • Minor other stuff here and there.
