I'd like to make a small version similar to "Rain room" as my graduation project but I don't know where to start, https://www.youtube.com/watch?v=jSup0tm86no

I've been searching the web for days, and I'm beginning to understand how it's build and what hardware I need, this is the the short list: 3D tracking cameras,injection moulded tiles, solenoid valves, pressure regulators, custom software, steel beams, water management system, grated floor

The main issue I have now is what kind of cameras that I should get and how many, I googled "3D tracking cameras" but couldn't understand the difference between them and which ones that are suitable for my project, I absolutely don't know any thing about cameras or how to use them with Java.

Never heard of a 3D tracking camera.

I would wager this was done with a regular camera and openCV library or something similar.

Since the rain only falls down the only information needed would be 'Top view.'

That way the sensors could turn on or off depending on that information. The camera would likely be positioned directly above or under the stage. Alternatively the floor might be covered with hundreds of LED sensors, as soon as someone walks over the light would be blocked thereby providing the same information. It could be using a combination of the two... I don't know.

However, the things you are taking about, steel beams, water systems, injection moulding. That's would be a lot of work for a grad project. I don't think you've thought about it carefully enough.

Thank you very much for replying, the designers said they've used "3d tracking cameras", and in another interview they've said "3d depth cameras"

as for sensors in the floor, this will only work if some one stepped on them,no?
I mean it won't work if people for example move their hands under the water, right?

other none IT things like water systems and injection moulded tiles I have someone that can help me with them, and I only want to make a small prototype.

You can buy one for $200.00

To break the beam you don't have to be directly over it.

Small or not the mechanics remain the same. The pump water system would be quite difficult.

This website is realy helpful, I never dealt with sensors or any other hardware, I will read this website carefully and I think it will be very usefull, Thank you very much
