circularity of voronoi cell

[shujing1111]

Hi,
I am wondering the circularity of the 2D voronoi cells. Like when I compared the voronoi cells with the comand: 1-circularity:lognormal(0.01,0.002) and 1-circularity:lognormal(0.3,0.002). Why do the voronoi cells exhibit more like circles with 1-circularity:lognormal(0.01,0.002) ? Because I think the larger the mean circularity, the more circle-like? But I got the more circle-like voronoi cells with 1-circularity:lognormal(0.01,0.002). Thank you

Jing

If you use 1-sphericity (which really is what it means, 1 - sphericity, when sphericity goes from 0 to 1), then the smaller the mean value, the larger the mean value of the sphericity.
