My idea is to make an app that lets you paint in AR on a virtual 2D canvas. Kind of like this app, but on a single plane and 2D: https://play.google.com/store/apps/details?id=com.vaytricks.PaintDrawAR
I also want the brush to be a little more sophisticated than just a flat circle, to have a bristle-like texture and to be able to blend colors together, like with oil paint.
The question is: is this possible to achieve at all and is it worth doing this specifically in Processing, or are there any better alternatives out there? Not trying to make some amazing highly performant application here, just something quick and dirty that would work more like a proof of concept. Thanks!
