I hope this is a good place to share this. I am an indie developer with previous experience working at Pixar Animation Studios, and I’m building a new kind of vector graphics application where the paths you draw can have a common border, and where you can intuitively sculpt them. This seems to solve many problems people have with Illustrator.
There are also tools to play with Z-ordering: you can have vector paths which are connected together (like the different parts making the glasses), but the different parts still have a different Z-order.
I hope you find it interesting, let me know what you think!
I am not allowed to put a link since I’m a new user of the forum, but you can try it out by downloading the free prototype at vpaint dot org.
