Starling is a new and very interesting grasshopper plug-in developed by Mateusz Zwierzycki.
'Starling mesh tools. These components enable mesh parametrization, so it behaves like a surface - you can evaluate points at any place etc. Is it accurate ? - not at all, but give it just a minute and you'll probably fall in love. Mesh morphing, remeshing, smooth curves evaluation (see group image), 3d convex hull and last but not least - slFastMesh - which will enable you to stop thinking about meshing parameters and start playing.'
