Ok, isosurfaces ARE cool, but...
...isn't that basically using POV as a very high-end
graphing calculator? ;)
I know, I know, I'm just envious 'cuz Moray doesn't
let you make them, and haven't finished any scene
enough to go in by hand and add things after building
the lot of it in Moray....
Just had a thought. You can really do away with
primitives, what with isosurfaces being what they
are and all...reduce entire scenes to one equation. ;)

Stop it! Stop it! I can't take it any longer! I don't have a fast PC and I keep
thinking up isosurfaces that I'd love to try but don't have the time for. Plus
I've still got 2 more years to pay my PC off :oP

That really is quite stunning. I just hope I can understand the
code.
Thanks for sharing.

The snowflake and wireframe box ones are great, I like those most.
Hopefully these all tile onto planes as well.

Thanks for the comments.

The ideal function (i.e. it gives short render time) is the
function which has constant gradient.
So, for example, sqrt(x^2+y^2+z^2) is better than x^2+y^2+z^2.

Isosurface doesn't consume memory so much. 12,000 of isosurfaces would be
ok for normal PC.

I noticed that the snowflake does not work on beta 8.
Use following function for beta 8.
#declare Func1=function(x,y,z){
min(min(f_rounded_box(GX(x,y,z)*1, GY(x,y,z), z, 0.1,0.8,0.1,0.1)
, f_rounded_box(GX(x,y,z)-GY(x,y,z)*0.5-.5, .2-GL(x,y,z),z,
0.1,0.1,0.1,0.1)
), f_rounded_box(GX(x,y,z)-.4, .2-GL(x,y,z), z, 0.1, 0.1, 0.2, 0.1) )
}
>Hopefully these all tile onto planes as well.
It's easy. Use following isosurface.
isosurface{
function{Func1(x,y,z)}
contained_by{box{<-S_W,-S_H,-S_R>,
<+S_W, S_H,+S_R>}}
max_gradient MAXG
}
