<novasilisko>
holy fuck i've almost got ellipsoids @egg @bofh
<novasilisko>
i have a bounds equation intended for raymarching and stuff that i was shown, but then i was presented with the idea of doing that iteratively
<novasilisko>
the function only returns a distance value, but from that i was shown how you can get a normal from a scalar field
<novasilisko>
so now i'm deriving a normal from that and can project that as a surface position
<novasilisko>
now, the reason that's iterative
<novasilisko>
the first one isn't accurate, it's only a bounds
<novasilisko>
but if you take the result position from the first projection, feed it in, repeat for a few times, you eventually get the correct surface position
<novasilisko>
IT'S WORKING
<novasilisko>
it has some cases where it goes weird though - the further away you get, the more weird it is

<novasilisko>
you don't even need that many iterations
<novasilisko>
just 2-3 is enough
