Interactive Non-Photorealistic Canvas

Using large, direct-touch displays, a non-photorealistic painting is made interactive, allowing the work with many strokes simultaneously. The essential difference to previous systems is that users can modify strokes even after they have been placed. This is achieved using a hybrid approach that takes the visual richness of pixel images and the flexibility of vector graphics. The implementation is based on the Display Framework that is being developed at Innovis.
