Group Shared Opposite Faces

[Jesus Nieto]

Hi Everybody. I've noticed a strong missing part in the Voronoi fracture SOP that would be very useful. I'm trying to generate some kind of shared face id. in order that if I had a box split it 2 parts, both inside faces from the pieces would share an attribute "id" that means they are complementary faces. I need to make this work for many pieces.

Maybe there is an already "out of the box" way to do this. Does anyone know a way to achieve this?

not sure I understand you correctly, but can't you just tick the "inside group" option on the Voronoi? you can then isolate inside pieces and give them a shared attrib value if you want.

// Primitive wrangle.

int pts[] = sort(array(i@cellpt, i@clippt));
s@common = sprintf("%d-%d", pts[0], pts[1]);

Seems it does the job. You can enable i@cellpt and i@clippt attributes in VF's "Attributes" tab.
