At the moment our software is limited to 3-channel spans, but we have 5-channel tentatively planned for Nthusim 4.1. For a cave you'd need 4 or 5-channel. I'm wanting to build up a cave project later this year myself, so getting 5-channel capability is definitely a priority.
1) With a CAVE, my assumption is you are just doing 1 projector per flat cube panel and calibrating to all the corners in an edge-butt method. That is very easily done with Nthusim. Just pull the edges of the Nthusim calibration grid to the corner locations and I'd add one centerline column and 1 centerline row to the grid so you'll compensate for any projection angle variation. It's very straight forward. Significantly easier to calibrate than our regular customers who are dealing with curved surfaces and edge-blends.
2) We have an optional FPS limiter setting in the Tools menu that you might set at 120 FPS. And also enable vertical sync in the video card driver and that should prevent taring. Taring can often be a function of the projector limitations, so depending on which projectors you use your mileage may vary.
3) Not 100% sure what 3D-Sync is, but Nthusim is certified for use with Nvidia 3D Vision Kit. Of the competitors out there, I believe we're the only ones that are using 3D shutter glasses to any extent.
Nthusim is developed by ImmersaView. It uses the same rendering and injection core as ImmersaView's Warp and SimVisuals products. Nthusim is their consumer product line. We have to delineate between commercial and consumer licensing in order for Nthusim to exist. If you're selling the CAVE builds to entities that are not charging out for the CAVE use, you might fall under our licensing arrangement. If you are selling CAVEs to commercial entities that generate income off the screen, I'd have to refer you over to ImmersaView to look into ImmersaView Warp or SimVisual licensing instead. ImmersaView allows Nthusim to exist as a product line strictly targeted at consumers. In exchange for that we refer all commercial/for-profit inquiries to ImmersaView and ImmersaView refers all consumer/non-profit/home inquiries to us. If you are selling your CAVE setups as a consumer turn-key solution, I'm sure we could come to an agreement to use Nthusim. It would also allow you to specify any particular features you'd like added to the Nthusim utility to better suit your needs.
