“Sketching of 3D Shapes”

We show that it is currently possible to interactively model complex 3D geometric shapes in a virtual environment in real time.  Our implementation uses virtual  shaping tools that follow 3D position and orientation of the artist's hand using a six degree of freedom stylus.  The tools mimic real world objects by directly deforming the geometric model based on collisions between the tool and model, such that the model locally deforms to the shape of the tool.  This talk will also discuss the physically inspired models of deformation using dynamically coupled particle systems.
