Starling_0.2 mesh tools. These components enable mesh parametrization, so it behaves like a surface - you can evaluate points at any place etc.

In 0.2 release, Starling enabled quasi-polyhedral mesh tools. These new components are organized in a new panel called "Alchemists" : 

How do they work ? You create polyline and each component converts it into polygonal mesh. Then it computes what it has to do. In the end component outputs polylines again, changed in some manner depending on components function.

Why truncation and dual ? Because with these two operations you can make most of mesh operations as described HERE. I.e. ambo (rectify) is truncation with amount of 1.

Special thanks to : Michael Pryor for constant help&support and David Rutten for great advices.

It's highly recommended to use Starling with Weaverbird and [uto] MeshEdit.

More examples explaining new components soon.
