    Most of the parts for this are ready and just need to be connected together. I added an evaporationRate control pipe command to our sandbox for a similar purpose.

    To the computer, the projector is just a display device. So that can be swapped with a monitor.

    The Kinect needs to be connected. The live depth image is what the shader uses as input. I have an additional (donated) Kinect on my desk and pointed at a nearby wall for development. I understand about comfort; I’d much rather work in my office than standing at our arsandbox in the back corner of a stockroom.

    Can you plug a monitor into the arsandbox computer and turn off the projector?

    Otherwise, what about a second computer? I use a separate computer with an Intel HD Graphics GPU for development, it will even animate water (slowly).

    My first guess is that you are not using “sudo RawKinectViewer”.

    If using “sudo” does not solve your problem, please copy-and-paste the exact command and the exact error.

    What on @maphew’s page is not working for you?

    I was able to change the fluid appearance by uncommenting and commenting lines in the fragment shader as the page directs. The line numbers may differ, so try matching the line contents to know which lines to change.

    The only idea I have… are you spreading your fingers enough?

    See this River Wey Trust video for a demo of good hand shape to activate the rain.

    Which distribution are you using? How are you trying to build VRUI? libdc1394-22-dev looks to still be supported on Ubuntu 18.04LTS and 20.04LTS. Newer Ubuntu versions have libdc1394-25-dev.

    The target disk does need to be close to CD/DVD size (12 cm diameter) before the DiskExtractor will mark it as a valid target. If I’m reading the code right, any diameter between 10.9 cm and 13.2 cm should work.

    If the transcript you included is complete, I strongly suspect that was not your first attempt building the software. Files left over from previous failed builds may be causing problems when attempting a new build. I recommend you delete the /home/john/src directory nd anything that mentions Vrui under the /usr/local directory before starting again from Step 3.

    Thank you for posting this output.

    The “glPrintError: Invalid framebuffer operation” message is a bit generic, but likely means the display card or driver will not work with SARndbox. Do those lines appear only when you try the rain gesture?

    I think your plan to use a new computer is the easiest path forward.

    Moving files after installation can cause them to not be found by other parts of the software. Why did you need “to copy files to the system folder”?

    I recommend removing and recompiling Vrui, Kinect, and SARndox.

    Congratulations on your new ARSandbox.

    AFAIK, there is not a list of short-cut keys because you can assign just about any key to any function. You did this tool binding during the installation when you used the “Extract Planes” tool. To find the available tools, explore the SARndbox menus that popup when you press a key.

    To create a stable set of hotkeys, see Step 15 of the Instalation instructions. The example WaterTool binds “1” to global rain and “2” to global drain.

    We have a BenQ MW632ST and it has worked well with our AR Sandbox. As you say, it over-projects the box edges. But the sandbox calibration compensates for that and only black is projected outside the box.
