The Canvas graphics engine was developed with versatility in mind. It was created with the notion that it would power a wide variety of creative apps, each with very different use cases.
The current lineup of apps that are using Canvas includes Animate for creating 2D, hand-drawn animations, Storyboard for planning out film sequences and editing animatics, and Painter for digital painting and photo editing.
In addition to those three, more apps are being planned for the future. One such app will be called Vector, and will serve as a way for artists to create professional quality vector illustrations.
