01 • Pathfinding
Geodesic Navigation
Plot orthodromic Great Circles across any bearing from 0° N to 315° NW. Watch animated 3D geodesic tubes grow in real-time led by traveling arrow indicators.
02 • Spherical Math
Antipodal Mathematics
Instantly calculate exact diametrically opposite coordinates. Enable core diameter lines to tunnel straight through Earth's center to its antipodes.
03 • Cartography
Dual Projection Sync
Simultaneously view dynamic WebGL 3D spherical rendering paired with synced 2D Mercator canvas projections with seam-clipping date line math.
