grouping voronoi fragments via piece area ?

[Mdonovan]

Hi guys,

 

I am trying to group my voronoi fragments by there size. Initially I tried to use the measure tool inside a foreach node, but that ended up giving me results via primitive and not via fragment.  Varomix helped me out tremendously and showed me a trick using a sphere within the foreach that let me grab the size of the sphere and assign that to a custom attribute on the primitive. This worked great.

 

Can anyone think of some other ways to do this and point me in the right direction ? I have some down time .. so its a good time to get comfortable with this.

 

Thanks

The old trick of promoting the primitive area to detail with "max" operation and then demoting back to primitive works fine here.

Something like this?

piecesVolume_dv.hipnc

in your foreach you want to measure area

attribute promote area from prim to detail as sum

attribute promote area again from detail to point as max

Then every point will have the same value.

 

You could also do the second promote to prim if you want.
