  Object growth macro demo (Message 1 to 3 of 3)

See my post in p.t.s-f.

Simple demo of my object growth macros.  The outer objects are semi-transparent
version of the inner objects with a growth size of 0.25.  The inner objects are
rendered with a growth size of 0.  Then everything is cut in half with a plane
to show the innards.

I'll repeat my question from p.t.s-f.  Does anyone know of a general way to
"grow" isosurfaces in this fashion?  Hmmm... depending on the function I'm
guessing that changing the threshold might work.  Any other ideas?

Thanks,

Michael

Your objects don't seem to have grown enough ;)

Heh... that's what I get for not checking back here often enough...

Here it really is :-)
