I just made this thing to solve a little problem...basically I needed the opposite of a carve...

given a circle, determine the sphere it would be carved from at a perticular latitude...

( see thanks Google! )


see the circle in the picture defined by the radius marked "a"

if that was all you had - how do you get the sphere in the picture...

just use this HDA!!!

damn...something is wrong with the stupid browser at work...

I'll upload it tonight when I get home....

here are the files:



these were made in H8.2 so please let me know if there are any issues with H9

the example file just has a circle SOP feeding into the od_zone_segment SOP

for further additions to this HDA here is another good page on spheres:
