Generating hills with PlaneGeometry in Three.js

Currently, I am searching for a straightforward technique to generate non-uniform hills in Three.js. By utilizing particles and positioning them with a sine wave algorithm like the following snippet:

 x = Math.random() * 1000 
 y = Math.sin( x / freq ) * amp
 z = Math.random() * 1000

Although this approach works to create a hill effect, the results are consistently uniform in height which does not meet my requirements. I have considered utilizing PlaneGeometry as an alternative solution, but I am unsure if this is the most effective method. Any suggestions or ideas would be greatly appreciated.

Answer №1

Are you looking to create a unique terrain randomly? If so, using Math.random might result in jagged edges instead of smooth curves.

For a more natural look, consider using a Perlin noise library. Check out this library for example: https://github.com/josephg/noisejs

You can also find detailed information on this topic in the book "Three.js Essential".
