Geroge!
Summary:
Teddy affords the user drawing 2D strokes and then automatically constructs potential 3D polygonal surfaces based on said strokes. Users interactively specify the silhouettes of objects, and the system attempts to create a 3D model which would match that silhouette (yes, I kind of just repeated myself). Keep in mind that Teddy was designed for rapid approximations. And the authors succeeded in this goal! Users were able to create basic models after as little as 10 minutes of getting used to the system.
Once Teddy generates an initial 3D shape, users are able to view their model from different angles and can modify with various gestures (as shown above). The rest of the paper focuses on the algorithms used to perform the various modeling operations.Discussion:
What I took away from this paper is that basic gestures can be used to perform some heavy back-end stuff... and to create animations that kids would love. What is important about this work is that the gestures seem intuitive, and thus users can understand how everything works quickly. I recommend that you look at the examples of each action for yourself, as this paper is filled with great screenshots of gestures in action.
Yeah, I gathered most of my understanding of the paper from the pictures.
ReplyDeleteThis one seems more interesting to me. From 2D to 3D has great potential for research, which is hard problem.
