Abstract
An input device is used to generate input strokes on a display device. The input strokes are acquired and resampled to be evenly spaced. Then, depth values are assigned to the resampled 2D points to form 3D contours. Variational implicit surfaces are fitted to the 3D contours to generate 3D blobs forming the 3D model to be rendered on an output device. The blobs can be merged by guidance strokes, and modified by target strokes.
