Modelling and Visualization of Implicit Surfaces

Caligraphic interface for free-form modelling
BlobMaker is a program for modelling surfaces using variational implicit surfaces. This system offers a solution to use variational implicit surfaces as a geometrical representation for free-form shapes.
The modeller allows new modelling operations to support stroke (pen-based) input. Shapes are created and manipulated using sketches on a perspective or parallel view.
The main operations are inflate, which creates 3D forms from a 2D stroke, merge which creates a 3D shape from two blobs and oversketch which allows users to redefine shapes using a single stroke to change their boundaries or to modify a surface by an implicit extrusion.
