GEODESIC
Structure Builder — 3D Geometric Construction
01. What It Does
Build geodesic structures from 5 primitive types. Snap-to-grid placement with real-time rigidity scoring lets you construct stable geometric forms and test structural integrity. Complete challenges to unlock tier rewards and progress through increasingly complex builds.
02. How It Works
A Three.js scene with OrbitControls provides the 3D workspace. Primitives are placed via raycasting onto a snap-to-grid surface. Connection detection within a 1.5-unit radius automatically links nearby hubs and struts. A rigidity algorithm scores your structure in real time. Challenge tracking with tier rewards persists progress to localStorage.
