Sometimes there is empty regions in power diagram. It looks like some regions are smaller compared to the normal Voronoi diagram? How is this possible and how is this useful? Here is an example:http://groups.csail.mit.edu/graphics/classes/6.838/F01/lectures/MedialAxisEtc/presentation/13.html[^]. On the left side there is an empty region (the empty triangle without a site).

This question is too general. Any example?

Yes I would be curious to see an example of this 'geometry' programming language as well.

@WesAday: I don't have rights to add other tags but I have improved my question.
@AndreasGierit: I have added a link with a power diagram with an empty region. I have tried 2 different algorithm and I cannot reproduce it at all? Can you elaborate?

This is a technical programming forum. What does your question have to do with programming?

I can't reproduce it with 2 algorithm. Maybe you can elaborate. I use Bowyer-Watson and the paraboloid projection.
