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.

Famous quotes containing the word creating:
“If the child knows the rewards and punishments in advance and knows that his parents will stick to them, the parents can actually empathize with the child’s plight while, at the same time, creating a firm sense of structure.... Your child will sense your resolve and your empathywhether you do this with words or just a sense of warmth.”
—Stanley I. Greenspan (20th century)
