Uformia, a software company with 25 years of research behind
its system (http://uformia.com/company), has announced that it is going to save the world
from polygons with the long-awaited release of its first product Symvol and a Kickstarter project
called MeshUp.
Polygons are a surface-based modeling approach that
has been used successfully in computer graphics for many years. However, they
suffer from major drawbacks when it comes to 3D printing. They commonly exhibit
holes and intersections that require time and effort to fix. Also, because
there is no inherent knowledge of an object's volume, multi-material and
material blends are impossible to define with polygons.
Uformia's approach is to model with pure mathematical volumes
(not voxels or parametric surfaces) so there is no costly fixing process before
an object is printed. To support the plethora of existing modeling tools, Uformia's engine also allows meshes to be imported,
automatically fixed and treated as volume objects.
A lot of scientific data that is a result of computer modeling
is presented in form of mesh with attributes assigned to it’s
components (polygons, vertices, etc.), what brings the same “polygon problem “ to
scientific data visualization area and makes Uformia's
products very useful at this area. For example partial solvent accessible
surface meshes are often brought with holes as they are generated for selected
parts of molecule, but not entire molecule . On Fig.1
is presented a caffeine solvent accessible surface for specific group (CH or
CH3) (here is an example from Jmol
documentation page is considered (http://chemapps.stolaf.edu/jmol/docs/examples-11/isosurface.htm?topic=12).
Fig.1
Solvent accessible surfaces described by such meshes may be
difficult to study and they cannot be printed in such state, so we need to repair it in order to obtain
closed mesh. An according volume
description can easily match
this repaired mesh objects
and afterwards can be printed (Fig.2, 3).

MeshUp will be available for Linux, MacOS and Windows. Symvol for
Rhino is available as a free and feature limited Maker version that works on
Windows and require Rhinoceros® version 4.0 SR8+. MeshUp
is now a live project on Kickstarter, accepting
donations.
