toto is the box;

warp { cristal{ Objiii , 50 }, { turbulence 0.4*<1,0.3,0.5> octaves 2 } }

Looks very interesting and promising.
Only things I want'to mention

> warp { cristal{ Objiii , 50 }, { turbulence 0.4*<1,0.3,0.5> octaves 2 } }
> titi is the sphere;

> warp {bourke{ Objiii accuracy 70 precision 20},{ turbulence 0.4*<1,0.3,0.5> octaves
2 }}
personaly I prefer another 'tesselate' keyword since
you can't use cristal or bourke in pigment{warp{}}
I mean
tesselate{
OBJECT_ID | OBJECT
METHOD { METHOD_PARAMS }
WARP { WARP_STATEMENT } | DISPLACEMENT{ PIGMENT | f_x(x,y,z),f_y(x,y,z),f_z(x,y,z) }
OBJECT_MODS
}
in your example
tesselate{
Objiii
bourke{ accuracy 70 precision 20}
warp{ turbulence 0.4*<1,0.3,0.5> octaves 2 }
OBJECT
}

Definetely cool!!!! It's time for a release! But about the deformation: Does
it simply move the vertices of the final tesselated object? In that case,
one can't apply much deformation before the triangles "collapse".
Deformation should be done before triangulation, AFAIK.

Not a problem, just do it with isosurface, and then tesselate it :-)

Definitely great!
Just one nit to pick... the correct spelling is "crystal" :)

Nice !
Will it be possible to save the meshes to files ?

Hi there!
I may be a bit late on this one, but all I wanted is to ask for your
resources (PDF-Files, Books, HTML-Pages) because I had wanted
to do some tesselation algorithms of my own (I'm THAT kind a
guy). I haven't found much, but since you were pretty successful,
I thought I'd just ask...
You can email me too, if you want to.
