Hi,

I use this code to make a gyroid. I export the surface as an stl using the stlwrite function somebody wrote.

[y,x,z] = ndgrid(linspace(0,20),linspace(0,20),linspace(0,20)); cx = cos(x); cy = cos(y); cz = cos(z); sx = sin(x); sy = sin(y); sz = sin(z); f = cx.*sy+cy.*sz+cz.*sx cla isosurface(x,y,z,f); view(3); camlight axis equal

Now I want the periodicity of the gyroid unit cells to either decrease or increase along one of the axes. I also want the transition from different periods to be a smooth gradient. I imagine storing coefficients that affect the periodicity in an array.

Thanks!
