Hello,
Another Matmod example: “Mesh Torus”.
Not easy to transcode. I've had quite a few difficulties.
The description refers to POV :
"Mesh Torus ( reference : http://www.povray.org/ ) by Abderrahman Taha
02/11/2019". I couldn't find the link :)
Fast rendering.
max_gradient calculated by POV is really small: 0.62.

and I can't stop looking at it. thanks. [insert superlatives here] :-). since
you, with the "maths" and all did find it difficult to achieve, there'd be .. no
hope for me, anyway, so, would you consider making the code/object public ?

The code ? Yes, of course !
The source is attached to this post.
Have fun ;)

I'd be interested to know what the "p" parameter was intended to be used for? I
looked through the code and it gets passed everywhere as an argument, but is
never used in the body of any of the function definitions.

That is spectacular and beautiful. And with a max_gradient of only 0.62?? Wow.

Your Prettyball_3 code produces a different result than your "Mesh Torus"
image-- although this example is quite beautiful as well! Did you mean to post
the Mesh Torus code instead? Like jr, I would love to see how you created it.

I made a mistake and uploaded the wrong file.
I now put the code for "MeshTorus".
This makes two samples.
Sorry...

Good observation Chris.
The 'p' parameter corresponds to the 't' parameter in Mathmod. It can be
used for animations and, in some cases, directly for isosurfaces.
For exemple in 'Holed Spheres', the 'ThickIso' function use this fourth
parameter : "ThickIso=max(Iso2(x,y,z,1), Iso2(x,y,z,-1))".
To keep my questions to a minimum, I've chosen to always use all 4
parameters, even if they're not all used, and then I want to test the
animations, so that's all ready.

I've now modified this file so that it runs a bit faster.
See the attached SDL file.
