It has been a very long time since I have POV-ed,
so I felt like playing a little with isosurfaces
again.

(I changed the contrast and brightness for this
image after rendering.)

isosurface blobs, a very fancy function, or both? as always, enjoying your
isosurfaces.

Ouch - this made me say "WOW" out loud. Very nice.

Impressive! Not the kind of isosurface I expected at all. Was it quick to
render? Can it be made to follow any spline path? If the answer is yes, I'd
definitely be interested in the code! It could be useful... :-)

Regards,
Hugo

Thank you. It rendered in 14m 32s on my XP2400 PC.

I havent started working on spline following isosurfaces (yet),
but Ryoichi Suzuki once made a macro for making isosurface ropes
that follows splines:

See the attachment of the above message for his "rope.inc" file.
This file must be edited a bit to make it work with POV-Ray v3.6.
I.e. some too long uncommented lines must be restored and the hat
operator; ^ must be replaced with the pow() function.

:)

It is 7 isosurface "shapes" that has been blobbed
together with a hyperbolic tangent function.

For the torus based splines there is some helper in isocsg library.
