Isosurface visualization is an important problem in computer graphics, with applications in elds
such as medical imaging, uid dynamics and chemistry. A very natural application for isosurface
visualization is found in scienti c visualization software, where ecient visualization of implicit
functions is of great importance. This paper proposes an ecient algorithm for visualizing threedimensional
isosurfaces of implicit functions in real time, with topology guarantees, subject
to constraints, and optimally with regard to some error measure. An implementation of the
algorithm in the open source interactive geometry software GeoGebra is discussed and analyzed.
