If it's TIN generation from 3D points that you want, it's hard to beat
Shewchuk's library called 'Triangle', as mentioned by Traian below.
For the related subject of triangulation of polygons, i've got a summary of
all known open-source options at
http://vterrain.org/Implementation/Libs/triangulate.html It turns out that
'Triangle' is great for that too.
