The current Kinect package only supports older first-generation RealSense cameras. Intel completely changed the way how software has to talk to the second-generation cameras (415 and 435).
I’ve tried a 435 camera and found it worked worse for the AR Sandbox than the original Kinect, so I didn’t prioritize writing a driver for it. We are currently looking into driver support for newer 3D cameras.
Let me dig up information about the DEM mode (where the sandbox guides you towards re-creating a 3D terrain model) and the water/lava/etc. shader magic from the old forum that went down.
In the meantime, here’s a list of AR Sandbox functionality that I may elaborate on in later posts:
- Basic topography mode (elevation colors, contour lines, etc.)
- Change elevation color map
- Change contour interval (vertical distance between contour lines)
- Change topography update latency
- Pause terrain updates
- DEM mode (load elevation model; visualize difference between sand and model)
- Save current sand surface as elevation model
- Water mode
- Global rain via key
- Global evaporation via key
- Mouse-driven rain/evaporation
- Rain through hand gesture
- Water simluation speed factor
- Change attenuation (roughly viscosity)
- Change water shader for different visual effects
- Geology visualization
- Draw sub-surface layer with arbitrary strike, pitch, elevation, and thickness
Yes, the AR Sandbox’s water simulation does typically not work unless there is a discrete GPU to run the necessary calculations.
The other errors you were seeing (permission problems when accessing Kinect and needing to run SARndbox with sudo, calibration file not existing, etc.) are due to something going awry during software installation. Please follow the steps in the software installation instructions carefully.
When it freezes, does it wake up again when you move the mouse or press a key? What kind of OS and desktop environment are you running? It might be that the OS puts the desktop in some form of low-power mode when it doesn’t detect user input for a while. There is code in the SARndbox application to prevent that, but some desktop systems might ignore that.
Does water work when you add it globally? Press and hold some key, e.g., “1”, and move the mouse to highlight “Manage Water” in the tool selection menu that pops up. Then release the key you pressed. Then press and release a second key, e.g., “2”.
This will bind a water tool to the two keys you chose. Now press and hold the first key to add water everywhere.
