Does matlab's delaunay triangulation still use cgal?

[alecjacobson]

It seems at one point matlab's delaunay triangulations were using cgal.

Matlab has so many different ways to get at a delaunay triangulation, it's really not clear to me now when it's using qhull and when it's using cgal. Does anyone know?

I'd like to do some quick tests in matlab with its cgal wrapper so that I can convince myself that it's worth committing to it for my c++ project.

Mathworks still uses CGAL triangulations. More than a hundred companies from SMEs to Big Tech also use them, which should answer the "worth committing" part :)

If you encounter any issue or have any API / usage question, you can count on support from an active community, and even commercial non-public development, depending on your needs.

Thanks. I didn't mean that it would be a sign of a good user. I meant that I could quickly call it on my data. Which Matlab function uses Matlab delauny triangulation?

I have no idea. We can help you to get started with CGAL. So you do not have to learn 2 APIs in a row.
