%center%http://www.cpsc.ucalgary.ca/~samavati/wiki/uploads/Main/dragon.jpg Naturasketch is an image assisted sketch-based modeling system. The user can start with an image of the model and provide important strokes of the object by simply drawing on the image. Then system creates a 3D model using the given strokes. In addition, the appropriate portions of the image are used as the texture for the model. Some modeling actions (e.g. make a hole, or add on-demand details) are supported through annotated strokes using a red pen. The underlying 3D models are feature-sensitive subdivision surfaces with controllable details. Creating detailed digital content is a major task in industries such as Game, Film and CAD, and requires well-constructed, high quality geometric models. However, even with sophisticated software packages, geometric modeling is still a challenging, tedious and time consuming task. Using this modeling tool complex models can be created in a matter of minutes rather than hours. %center% Attach:natura_sketch.png %center% %width=400px% http://www.cpsc.ucalgary.ca/~samavati/wiki/uploads/pictures/mechpart.jpg %width=400px% http://www.cpsc.ucalgary.ca/~samavati/wiki/uploads/pictures/xboxctrl.jpg !!!!Demo *Find a demo of the early version of this system at %newwin%[[ http://www.youtube.com/watch?v=4rKyWqPMrWA&feature=share&list=UU6JcSnf-Ts8Fr-cZtIuMiLA |Youtube]]%% !!!!Commercialization: *[[http://grvis.com/index.php/grsketch/ | GRSketch]] ======= !!!!Achievements * [[http://grand-nce.ca/newsandmedia/news-container/2013/three-grand-researchers-2013-digital-alberta-award-winners | Digital Alberta Awards 2013, Best in Cross-Platform, GRSktech (commercial version of Naturasketch), June 2013.]] *Received IEEE Computer Graphics and Applications 2011 Best Paper Award (see the related papers). !!!!Related papers * ''NaturaSketch: Modeling from Images and Natural Sketches'', Olsen, L., Samavati, F.F., Jorge, J., Vol. 31, Issue 6, pp. 24-34, IEEE Computer Graphics and Applications 2011.
