Thruster Activity:
``` This HTML file creates an interactive 3D WebGL visualization of your wing-spar seastead design. The visualization includes: 1. **Wing-Spar Structure**: The main wing shape with the specified dimensions (39' long, 10' chord, 5' thick) 2. **Water Interface**: Semi-transparent water plane showing the 60% submerged operation 3. **Internal Features**: - 5 internal floors (brown planes) - Heavy equipment on the bottom floor (dark gray box) - Platform above the spar with railings - Solar panel structure above the platform 4. **Thrusters**: 8 RIM-drive thrusters (4 on each side) with visualization cones that change color based on thrust 5. **Interactive Controls**: - Forward thrust control - Turning control (differential thrust) - Pitch control - Visual thruster activity indicators 6. **Camera Controls**: - Click and drag to rotate the view - Scroll to zoom in/out The seastead gently bobs in the water, and you can use the controls to simulate thruster operation for maneuvering. The thruster visualization shows which thrusters are active and their relative thrust levels. To use this file, simply save it as an HTML file and open it in any modern web browser. The WebGL rendering will work in Chrome, Firefox, Safari, and Edge.
