(and this future looks promising!)
VPaint is an experimental prototype based on the Vector Graphics Complex (VGC), a technology developed by a collaboration of researchers at Inria and the University of British Columbia. It allows you to create resolution-independent illustrations and animations using innovative techniques.
DISCLAIMER: VPaint is considered BETA, and always will: it lacks plenty of useful features commonly found in other editors, and you should expect glitches and crashes once in a while. It is distributed primarily for research purposes, and for curious artists interested in early testing of cutting-edge but unstable technology.
Because VPaint is just a prototype, we may or may not release new versions. However, we are currently developing two new apps, called VGC Illustration and VGC Animation, based on what we learned from VPaint. These new apps will significantly improve performance compared to VPaint, and have more features. See www.vgc.io for more details.
We are running a Kickstarter campaign from September 7, 2021 to October 7, 2021, in order to raise enough funds to develop VGC Illustration. More information on the video below:
With VPaint, the lines composing your illustration or animation are not Bezier curves, but hand-drawn curves called edges. You can conveniently set the width of drawn edges by holding CTRL. If you are using a pen tablet, VPaint can use the pressure information to generate edges with variable width.
Once drawn, your edges can be easily edited à la ZBrush: simply push the curve using our sculpting tool. The radius of influence can be almost instantly changed at any given time by holding CTRL. In the same way, curves can be smoothed by holding SHIFT. The width of curves can also be edited locally by holding ALT, making possible to intuitively design curves of variable width even with a mouse. Junctions between edges are tracked by VPaint, and always preserved during editing (unlike in most other vector graphics editors, where Bezier paths are all independent from each others).
Using the paint bucket tool, it is easier than ever to color vector illustrations. Just click on a region bounded by existing edges to fill this region with the current color, creating what is call a face (= painted region). Unlike most other vector graphics editor, the face keeps track of which edges define its boundary, and thus editing this boundary automatically update the painted region. Junctions between faces are tracked by VPaint, and always preserved during editing.
At the bottom of the window, there is a timeline to let you create an animation by drawing several frames, and you can easily play/pause with the spacebar, and go one frame left or one frame right with the arrow keys. You can either draw everything frame by frame, or copy elements from some frame (CTRL+C) and paste them at another frame (CTRL+V). You can also do a special paste called motion-paste (CTRL+SHIFT+V) to paste elements several frames away with automatic inbetweening.
For better control over the timing and trajectory of your animation, you can overlay several adjacent frames of the animation at the same time. Also, you can split the view into as many views as you want, to show and edit side by side different frames of your animation.
