Creating of Heightmaps
Heightmaps can be created by hand with a classical paint program or a special terrain editor. These editors visualise the terrain in 3D and allow the user to modify the surface. Normally there are tools to raise, lower, smooth or erode the terrain. Another way to create a terrain is to use a terrain generation algorithm. This can be for example a 2D Perlin noise function. Another method is to use real world data for example from satellites.

“Contention is inseparable from creating knowledge. It is not contention we should try to avoid, but discourses that attempt to suppress contention.”
