A lightweight component for Unity that produces procedurally generated terrain using the Diamond-Square algorithm.

Unity-Diamond-Square

A lightweight Diamond-Square component for Unity. Last updated for Unity 5.4.2f2.

Diamond-Square

The Diamond-square algorithm is a two-dimensional version of the Midpoint displacement algorithm. The algorithm is used to manipluate heightmaps to produce a natural-esk terrain.

More details can be found at the following links: https://en.wikipedia.org/wiki/Diamond-square_algorithm http://www.paulboxley.com/blog/2011/03/terrain-generation-mark-one http://stevelosh.com/blog/2016/06/diamond-square/

How To Use

1. Import the script into an existing Unity project.
2. Attach the script to a GameObject either in the inspector or during runtime.
3. From a seperate script, during runtime, call the Reset function to flatten the terrain.
4. Call the ExecuteDiamondSquare function to execute the Diamond-Square algorithm.

Results

The following images show the result of this algorithm. The water depicted in the photos are NOT a result of the algorithm; this was added seperatly to show height.
