Mountain Tide 🌊⛰️

An experimental simulation inspired by Liu Cixin’s short sci‑fi story “Mountain” (《山》). It visualizes how a massive celestial body distorts a local ocean surface through Newtonian gravity and a shallow‑water height‑field model. ✨

What it does 🔭

• Models a local ocean patch with volume conservation and damping.
• Applies Newtonian gravity from a spherical body (with a smooth transition inside the sphere).
• Renders a fixed‑view 3D height field on an HTML canvas.

Controls 🎛️

• Mass: adjust the body’s mass (log scale).
• Volume: adjust the body’s volume (log scale) and radius.
• Height: distance from sea level to the sphere’s bottom.
• Grid size: resolution of the height field.
• Reset: restore a calm ocean surface.
• Drag to rotate, scroll to zoom.

Run locally 🚀

Or serve it with any static server:

python3 -m http.server

Then visit http://localhost:8000.

Notes 🧠

• This is a visual, not scientific simulation. Numbers are stylized for readability.
• The camera is fixed to a cinematic 45°‑ish view to emphasize the tidal bulge.
