[ff3d-users] Povray geometry

[Denis Gueyffier]

Hi,

I'd like to use the following geometry in FreeFem3D:
isosurface{
function{ y - sin(x*4*pi)*0.1 }
contained_by{box{<-1,-0.5,-1>,<1,1,1>}}
pigment{ color rgb<1,0,0>}
}

(see the rendered shape at
http://www.f-lohmueller.de/pov_tut/all_shapes/shapes920f.htm top of the
page)

But the pov-ray interpreter doesn't seem to handle this geometry.
Is there anyway I can define this shape inside FreemFem? or should I use a
mesh generator?

Thanks,
