Planetarium at home for children, how to synchronize projectors?

Question

Do it yourself

Good afternoon,
there is a desire to make a planetarium for children at home, teach useful things and use, so to speak, like a holodeck. (there is already one MoCap system at home)
But I don’t even understand and don’t know where to start with synchronizing projectors and what software for the planetarium is. Found only stellarium.
there are three rooms where it would be possible to build 90m3, 280m3 and 600m3
I would be glad for any links and kicks in the right direction.

Answer 1

A very strange wish.
A planetarium is a room for lectures with visual aids.
Are you going to lecture children? How many listeners will you get? Are you confident in your qualifications as a popular astronomer?
Do not fool around, put Stellarium , buy an inexpensive telescope, if you want to work with your hands - screw a camera to it (there is one thing on the farm).
And, of course, take your children to a real planetarium .

Answer 2

A planetarium needs a spherical dome and a spherical mirror" (google "spherical video, for example - http://videophotopro.ru/showthread.php?3155-What-and-... ").
According to these conditions, it is better to use Сelestia (celestiaproject .ru) and Stellarium. It will be clear on a regular flat screen. If the goal is to display a picture from two or three projectors, then a specific video card is needed (for example, with support for nvidia surround people.overclockers.ru/gromFX/17236/NVidia_Surroun... ) .
