Hi, Adam, I use the delaunay triangulation package for triangulation, and I
found out that the four vertices of computed cells would lie on the same
plane, as the images(I render only the cells incident to one point). But
According to my understanding of delaunay triangulation, such kind of
triangulation would not be a right delaunay triangulation.

Here is my code:

//define DT as delaunay triangulation.
std::vector< Point> points; //restores the points of input mesh, saying a
uniformly sampled cube
DT.insert(points.begin(),points.end());

Any idea about the problem? Thank you very much.

Monica
