But the maths behind the sphere isosurface, according to the above page, mention an equation along the lines of 1 - sqr(x) + sqr(y) + sqr(y) - pretty much the opposite. So to "guess" the heart equation, I reversed the above heart function (in the pov ray tuts), in the same vein, and ended up with the right thing. Only issue : the artefacts, now reduced, don't depend on a linear interval. They seem to depend on sign variations of the function : so what I am looking for are the zeros. And honestly, zeros of a sixth grade function.... Anyway, clap take two, [url=http://www.beyondwonderland.com/knowledge/javascript/Valentine_special/isoheart.html]Argo's valentine scriptlet[/url] Loading...
