I wanted to create TINs from 3D points (about 7 million in every file) using qhull.
can anyone suggest a place where i could probably see how to do this? thanks!
I've never used QHull since it is hard to integrate as a library into an existing project. Try out Triangle; it is specialized for 2D and is very easy to use (it comes with an example of how to call it from other C code).
