Voronoi 2D cells missing under certain circumstances

Grasshopper

Hi everyone,

I came across a strange problem when doing a simple 2d voronoi.

Some cells can go missing in some occasions. (please see attached…)

Does anyone know the cause behind the problem?

Much appreaciated.

Give the voronoi diagram a boundary.

Thanks MIchael,

That solved the problem :slight_smile:

Was originally thinking it grows with the input points so I avoided providing boundary intentionally,

but looks like it has to have one :slight_smile:

Still a bug though. Points that lie on circles always cause problems with delaunay/voronoi geometry because the state of the diagram is a limit case, but it should be handled better than this.
