    Hey Oliver,

    Thanks for getting back to me with a clear answer. Are the contour lines created by SARndbox? I’m reading your code. It’s hard since I don’t know how your other code (kinect and VRui) works. From reading your code, I realized that dynamically changing the location of the height=0 plane is also going to be very difficult. The base height extracted from BoxLayout.txt is used a lots of function calls or instantiations. The program doesn’t have a main() so I suppose main() is inside VRui and compiled with SARndbox code. I was going to have two push buttons adjust the height of zero height since sometimes you have too much or too little sand. I think it’s going to be quite hard.

    I found in the SARndbox 2.3 source code that some of the folders are pointing at the 4.2 version of VRui. I’ll give it a try to see if I can update them and compile it to run with VRui 4.3. It’s not easy to modify the source code. I wish there’s an update.

    I’ve used mx631st. It’s very nice. I’ve not used ms630st. Benq projectors have serial port command capabilities. You can turn them off or on eco mode when there is nobody at the sandbox, that is if you have sensors to detect people.

    Are you going to make a 30″ by 40″ sand box? If that is the case, then the throw ratio is too short. Your projector may be too close to the sand box and may cast a shadow over the field of view of your kinect sensor. I use throw ratio close to 1.0 projectors. This way the projector and kinect sensor are at the same height.

    That looks pretty good to me. I have done a recent one with i5-7400 and GTX 1060 3G. Water seems fine although occasionally I see message of “running out of time”. It doesn’t bother me. The slowing down is not noticeable by anyone playing the sandbox.

    I cleaned and made sarndbox 2.3 again but still it wants files on Dr. Kreylos’ computer LOL There might be a newer version that’s not posted yet. I did everything I could. The Vrui 4.3 and Kinect 3.3 are working. I could run RawKinectViewer and extract plane and points. I couldn’t calibrate the projector as it is part of the Sarndbox program that I suspect needs an update as well.

    OK, here is my detailed post regarding the USB button box I constructed. Hope it helps:

    OK, here is the box I built to delay USB connection to the PC for 10 seconds so Kinect won’t be detected by bios and cause freezing.

    Here is a photo of the adapter connected to the PC:

    Inside the box are an arduino and a relay shield.

    Had the same problem for a while. Forced me to memorize the location of the items on the menu 🙂 The above was provided to a similar post and works perfectly. Makes sense too.

    An xbox360 kinect is cheap enough on ebay. I wouldn’t wait for software release.

    Awesome! Thanks for sharing. I have thought about Alienware Alpha. I’m glad that it works. I am considering the model with i3 instead of i5. When you are running the simulation with water flowing all over the place, how much cpu are you using anyway? I am doing ok with an i3-7100 with nvidia cards.

    Here is my rain and dry button box I built with Arduino:

    The buttons are flashing periodically to invite people to press them. These buttons are essentially keys ‘1’ and ‘2’ so I can use them in calibration programs as well. Later I will add two more buttons on the underside to start the program and shut down the machine.

    I decided to build my own box with buttons and arduino. I’m hiding a button under the box for shutdown. Hopefully there will be enough space in the box to have a cycle button. Great idea! Will post my story once I get mine working.

    metamedian,

    I have the same issue with my GTX 750 Ti card and I use the Nvidia driver. So your method is to switch video driver to see the larger menu? After you go back to Nvidia drivers, then are the menus back to normal? How do you install noveau drivers? I am a bit of a novice on Linux. This issue is very annoying and it’s testing my fine motor skills when selecting tiny blurry menu items!
