Tsugite: Interactive Design and Fabrication of Wood Joints
summary
An interactive system called Tsugite lets users design voxelized wood joints with real-time metrics for slidability, fabricability, and durability and exports toolpaths for 3-axis CNC milling; a path planner conditionally rounds outer corners to match inevitable inner-corner fillets so parts assemble. The gallery enumerates designs by reducing possibilities from 134 million to 260,000 via a height-field restriction. A 20-person study shows 8 vs 13 errors with feedback, and full-scale pieces including a chair and table fabricated from the generated joints successfully assemble and support load.
