SoftGenLock enables active stereo for Linux Clusters

Thought SoftGenLock source code an documentation are still available, we do not have the necessary resources to maintain it properly. We suggest you try first similar solutions better maintained developped by other teams:

• WinSGL: a software genlocking solution for windows developped at ETZH
• GenLock: a software genlocking solution for Linux developped at HLRS. It works without real time system with linux kernel 2.6

High quality image projection and active stereo rendering require multi display systems to have their different video outputs swaplocked and genlocked. Swaplock is related to frame buffer swap synchronization. Genlock is related to video retrace synchronization. Active stereo also require quad buffering and left/right eye buffer flipping synchronized with the video retrace.

Except for some high end cards, off-the-shelf graphics cards do not support swaplock and genlock. Especially for Linux, today's graphics card drivers generally do not enable quad buffer page flipped stereo.

We developed software solutions that do not require specific hardware or access to the driver source code. Swaplock support is integrated in Net Juggler. Genlock and active stereo support are gathered in the SoftGenLock library.

Currently, SoftGenLock is available for Linux. It should work with any graphics cards, but it was only tested with Geforce cards and 3dfx cards. Please email us if you get SoftGenLock running with other graphics cards or OS.

SofGenLock is now available for download.
