Feel the math -- Surface

thingiverse

Have you ever struggled to picture how a surface looks? With OpenSCAD and 3D printing, it's easy! You can write an equation z=f(x,y), print the result, and actually feel the surface. Sample STL files are available for the equations: z(x,y)=-0.015(xx+yy); z(x,y)=3(sin(10x)+sin(10y)); z(x,y)=0.01(x+y)(x+y); z(x,y)=0.001xxx+0.02y*y; You can use these files as a library for your model.
