Interactive tools for image-based stereoscopic artwork

In this paper we describe a set of interactive tools that we have built as an extension to our image-based stereoscopic non-photorealistic rendering system. The base system is capable of automatically turning stereoscopic input images to stereoscopic pictures that resemble artwork, including concept drawings, cartoons and paintings. The tools described here aim to complement the traditional stereoscopic viewing experience of the end-user by enabling him to interact with the perceived stereoscopic space. The observers of the generated artwork can easily enhance the perceived depth by manipulating the two artistic-looking projections while stereo viewing. The users can examine the stereoscopic artwork via the use of stereoscopic cursors, as well as explore the structure of multi-layered artwork by peeling away layers at different depths to reveal other layers, initially occluded.
