A browser based random world generator.
Generates an initial random (or preset) elevation model, then assigns Earth-like precipitation and temperature.
- All operations are done in a spherical coordinate system. This is slower but means the core model is a sphere, so no projecting, and the poles "just work".
- Non-iterative approach. Precipitation and temperature are functions of elevation and latitude only. This isn't really accurate, but I wanted to see how close I could approximate it (ever wonder why none of the hottest spots are near the equator?)
- Fractal terrain inspired by mid-point displacement applied to a sphere. Theoretically unlimited detail, in practise limited by texture size/zoom strategy.
Client side only. Clone/download and open index.html in a browser.
Browser GET arguments:
seed: Any initial seed string or number, or "earth" for Earth-like elevation.numberOfControlPoints: Number of points to initially assign to sphere. Default: 256.detailLevel: Number of times to sub-divide initial control points by. Higher creates more detail but performs exponential slower. Default: 4.seaLevel: Sea level expressed between 0 and 1. Higher means less land. Default: 0.7.textureHeight: threejs texture height in pixels. Higher is better, but browsers have limits. Default: 512.bumpMap: "true" to bump map texture.showTemperature: "true" to show temperature gradient instead of terrain.showPrecipitation: "true" to show precipitation gradient instead of terrain.showPoints: "true" to show control points.
