Hearts Joined

Heart shape via the function: f(t) = [18 * pow(sin(t),3), 15 * cos(t) - 5 * cos(2*t) - 2 * cos(3*t) - cos(4*t) ]; You can experiment with function parameters and generate OpenSCAD code on the interactive page http://kitwallace.co.uk/3d/knot-braid.xq?preset=9 Two joined hearts use a hulled-sphere construction because the standard polyhedral construction doesn't play well with CSG operations in OpenSCAD
