I'm pleased to announce that vDome-Max, a fulldome multi-channel projection software, is now open source and freely available through GitHub:
We are currently using it for real-time slicing and projection mapping in a 2K fulldome theatre at IAIA in Santa Fe, NM.
It is designed to accept 2048 x 2048 dome-masters through Syphon, TCP, or direct video playback.
If anyone knows of optimizations that can be done in the program, please let me know. Once thing that I've been thinking about it to have a gui-less version that can be used after calibration is complete.
