We present a framework for automatically creating a type of artwork in which 2D and 3D contents are mixed within the same composition. These artworks create plausible effects for the viewers by showing a different relationship between 2D and 3D at each viewing angle. As the viewing angle is changed, we can clearly see 3D elements emerging from the scene. When creating such artwork, we face several challenges. The main challenge is to ensure the continuity between the 2D and the 3D parts in terms of geometry and colors. We provide a 3D synthetic environment in which the user selects the region of interest (ROI) from a given scene object to be shown in 3D. Then we create a flat rendering grid that matches the topology of the ROI and attach the ROI to the rendering grid. Next we create textures for the flat part and the ROI. To enhance the continuity between the 2D and the 3D parts of the object, we include bas-relief profiles around the ROI. Our framework can be used as a tool in order to assist artists in designing such sculpture paintings. Furthermore, it can be applied by amateur users to create decorative objects for exhibitions, souvenirs, and homes.
