Gradient of Grain (MAA Focus article)
A short Art Department piece in MAA Focus describing the making of Gradient of Grain. The wood grain is treated as the natural geometry of the material — level sets recording the tree's growth — and the cuts follow the gradient direction perpendicular to it, which is also the cleanest direction to carve. An algorithm starting from the centre draws gradient lines outward, splitting them when the spacing grows too large; the wood is photographed, grain lines are traced, and the resulting network of paths is sent to the CNC machine.
