Hi,
I still haven't got to grips with isosurfaces... I'm trying to utilise the
built in "heart" function, and it's taken me absolutely ages to actually get
the thing to appear.. but now I cannot get rid of the ugly horizontal line
which bisects the heart...
Any ideas? My code :
isosurface {
function {"heart",<.004> }
contained_by{ box {<-.75,-1.2,-1.2>,<.75,1.2,1.2>}}
max_gradient 5.958
sign -1
accuracy 0.0005
texture {pigment {rgb <.2,.5,.9>} finish {specular .7 roughness .001}}
rotate <0,90,90>
}
Not sure how I arrived at 0.0005 for accuracy.. could this be optimised?
thanks

That line seems to be specific for the "heart" function, it's also visible
in Smellenbergh's isosurface manual: http://users.skynet.be/smellenbergh/
and Mike's Isosurface Tutorial:

You arrived there by typing it in :-) You can often use the default value,
unless it is not accurate enough, which usually only occurs with noise3d
and pigment functions.

Actually, I must have arrived there, and *then* typed it in :-)
