FLIGHT DIRECTOR'S GUIDE
HELIO ARC / AETHERLINE–44 is a fictional orbital infrastructure simulation. Explore four engineering scales; adjust a climber's acceleration, payload and available grid power, then dispatch a climb. Queue cargo to simulate logistics. Simulated time is accelerated to make high-altitude travel observable.
CAMERA
Drag to orbit, scroll to zoom. Use WASD for planar travel and Q/E for descending/ascending. Hold Shift to move faster. Click scene territory buttons to relocate.
FLIGHT PHYSICS
Altitude and speed integrate with semi-implicit Euler steps. The simplified force, tether load, electrical draw and regenerative descent calculations are for educational visualization rather than engineering certification.
Includes a no-network offline canvas preview. For the complete Three.js PBR experience, install the pinned Three.js runtime using the vendor script supplied in tools/.
