Metaballs

I found an interesting article about marching cubes and tryied to port it to a QCplug.
So… yet another sluggish metaballs.
The calculation is done on the CPU, hence a speed ok at low resolution, but quite troubled at higher rez. / polycount.
Still, the effect is quite nice and blobby. Nothing new here, but a nice opportunity to learn how to make polygons from a cube_grid.

and more interesting: Hairy Balls…
