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.
