I was printing these dualstrusion gyroids at the Seattle Mini Makerfaire on my new Replicator (they only take about 30 minutes). There's also a couple of single color versions included. You can stack these in all three dimensions to form a continuous surface.

You'll need to intersect it with with a sphere. I use OpenSCAD for that (see my puzzle derivative to see this gyroid intersected with a rhombic dodecahedron). A sphere is generally x^2+y^2+z^2=r^2.
Hi.. I making a projekt, where i'm studying artistic shapes from mathematical formulas.. Do you know which formula is used to make the gyroid above, before post-processing..?
..i know the formula for the gyroid is: f(x,y,z)=0, but i'm unsure as to how i limit that shape to a ball.. i was thinking along the lines of: (x^2 + y^2 + z^2)*radius = 1
Do you know..?

I made the Gyroid shape in Matlab using gyroid.m and a tool from the file exchange that writes STLs. I used OpenSCAD to adjust those files into the ones I print. GyroidThin, Thick and Half are the intermediates between Matlab and OpenSCAD, so you can make whatever you want out of this surface.
