I just couldn't resist the temptation to try and
emulate some kind of sphere-sweep with iso-surfaces.
So yesterday I sat down and did some math.
This is one of the resulting images.
It shows 3 iso-surfaces, and the equation you see
the contours of here is a "sombrero" equation:
y = -10*sin(sqrt(x^2 + z^2))/(sqrt(x^2 + z^2) + 3)
Because of my slow PC (0 pixels per second), I had
to render it without any anti aliasing. And I saw
this morning that I had used too much light in the
scene. So to try and fix all this I cheated. =(
(I.e.: I used an image editor to adjust the gamma,
blur it slightly and then to resize it with
resampling.)
