1. Sentence: We show how 2D vector art drawings of a cartoon from different views can be used to generate a novel structure, the 2.5D cartoon model, which can be used to simulate 3D rotations and generate plausible renderings of the cartoon from any view. (2nd sentence, Abstract)
2. Problem: Generating a 3D model is time-consuming, complicated and many stylistic elements of 2D drawings cannot be adequately reproduced in a 3D model.
3. Key Idea: Associate each stroke of the cartoon with 3 properties – stroke’s shape, position, and Z-ordering and interpolate their values to generate intermediate views from the 3-4 key views of the cartoon (set by the artist).
4a. What the paper does: Allows the artist to draw the cartoon in a few ‘key’ views with automatic Z-ordering (including manual override capabilities) and manual control over visibility and Boolean operations. It then generates a ‘2.5D’ model of the cartoon to allow viewing from any angle.
4b. What it could be used for: The interactive tool designed by the authors allows creation of 2D animations in a simple and intuitive way. It also enables cartoon objects to be placed in an interactive 3D environment in which the user controls the viewpoint – can be very useful for simple games.
5. Resources: Video, Presentation, Modeling tool from paper’s web-page
