  Accuracy is not always the answer. Sometimes you have to play with
the max_gradient.

main(i,_){for(_?--i,main(i+2,"FhhQHFIJD|FQTITFN]zRFHhhTBFHhhTBFysdB"[i]
):5;i&&_>1;printf("%s",_-70?_&1?"[]":" ":(_=0,"\n")),_/=2);} /*- Warp -*/

Tried max_gradient 100000000, no success. It suspiciously
fast parse the file, the render is unfinishable.

When I try method 1, it places some "trees" but at wrong
places (I think) and isosurface itself has many holes
