hello.
in the voronoifracturepoints-sop, what is the “exterior” scattering of points good for?
i understand that the SDF/IsoLevel is being used for scattering inside and on the surface, where the voronoi pieces are being generated.
but outside? where are these pieces?

i am a houdini noob….

thank you in advance

maybe it anwser your question but look at this video:

http://www.sidefx.com/index.php?option=com_content&task=view&id=2350&Itemid=344 [sidefx.com]

it's shows also the voronoi sop.

I usually use this for making group of the small pieces inside of the Big pieces !

thank you very much, Joker.
i dont know why but your scene makes my Apprentice crash when opening it.
i will try nevertheless.

but from the screenshots you attached, i get a better understanding, thanks a lot. one question though: it seems like the blue/exterior scatter points affect the parts inside the geo. is this true? and if yes, how? i thought they are outside?
or do i miss somehtin crucial here?

EDIT: i managed to open the scene and had a look inside. i guess it has something to do with the “impact offset” (which is set to -1.55), right?
that would make sense to me. am i right or totally wrong?

ok, got it.
outside means not outside of the geo but outside of the metaballs which are created for generating the cells.
thanks anyway.

Yes , Exactly !

Also to achieve best result you should set “impact offset” correctly :wink:

yes, thank you Joker386.
