A generative artwork exploring the mathematics of wood grain, anisotropic growth patterns rendered as layered curves that evoke the cross-section of a tree.

Gradient of Grain, finished CNC-carved oak slice, 15×15×2 inches, 2024
Step 1: oak slice photographed in the CNC and registered in Rhino
Step 2: growth rings traced as curves in Rhino
Step 3: gradient paths computed and overlaid on the wood
Step 4: mid-cut in the CNC, radial pattern emerging
Maquette for the idea, earlier carved oak block with radial grain paths, 2014
The oak tree felled on the land where the pieces are made
Oak cross-sections stacked and drying in the studio
