In 2011, came up with a concept for putting the Rhino command icons onto the then new iPad and using it as an command input device. Built a web application that would allow dragging and dropping from the full library of icons in order to build custom palettes of commands and make them downloadable for use with Rhino. Called it RhinoTap.
This was based on automating a keystroke app that was available in the iTunes stores, so did not need to go through the Apple app store approval hoops.
Got permission from Bob McNeel to use the icon library for this specific purpose. Was fun, didn’t get any traction, but learned a lot about PHP web based scripting.
The original video seems to be lost to time. Youtube doesn’t give any clues of what the original was, hard to search for it.
I have the php code archive of the website, but it has not been looked at or running for a decade.
It wasn’t that complicated as I recall, press button, ipad keystroke app sends text to rhino command line.
Drag and drop interface used individual icons and their respective command strings, php followed mouse positions and wrote an overall image file and the command line file in the format of the app.
