Completely agree. I thought this was going to be some underwhelming nonsense, but that is legit impressive and something even a non-artist could benefit from.
Arguably non-artists benefit the most. This is a time saver for skilled artists but a whole new ability unlock for the unskilled ones.
I was going to write how this would be cool in a kids drawing app but the thought that they might never feel the need to draw something from a different angle. I wonder what other activities have been lost to time and technology.
Why might a kid not want to draw something from a different angle? In my introduction to drawing course I was asked to draw my non-dominant hand every day for a week, each time from a slightly different angle.
