A Suggestive Interface for Image Guided 3D Sketching Steve Tsang, Ravin Balakrishnan, Karan Singh, Abhishek Ranjan Motivation 2 System Overview 3 System Features • Sketching • Image templates • Image-based interaction techniques • Suggestions 4 Previous Work • • • • Zeleznik, Herndon, Hughes. (199?) SKETCH: An interface for sketching 3D scenes Igarashi, Matsuoka, Tanaka. (199?) Teddy: A sketching interface for 3D free form design. Igarashi, Hughes. (199?) A suggestion interface for 3D drawing Grossman, Balakrishnan, Kurtenback, Fitzmaurice, Khan, Buxton. (200?) Interaction techniques for 3D modeling on large displays 5 Image Guided Drawing • Image Based Interaction techniques • • • Snapping Gluing Pinning 6 Snapping • • Drawn curves attracted to image template curves Intensity maps generated as image templates are applied 7 Gluing • Allows user to specify parts of the curve to be excluded from snapping algorithm 8 Pinning • Fix a curve to a particular point 9 Pinning 10 Geometry Suggestions • System suggestions: • • • Closure Extrusion Database suggestions • User responses: • • • Accept Delete Ignore 11 Closure Suggestions 12 Extrusion 13 Database Suggestions • Curve signatures 14 Database Suggestions 15 Curve and Line Creation • One-handed tape drawing technique • Press button for line drawing 16 Gestures • Activated by pressure on pen • stroke, cut, delete 17 Contributions • Integrating existing images as a template • Image-based interaction techniques to build 3D geometry • Sketchable query to retrieve database geometry • Geometry suggestions 18 Acknowledgements MITACS DGP lab members Stan Pinkie and Mercie 19
