A heightmap created with Terragen The same heightmap converted to a 3D mesh and rendered with Anim8or. In computer graphics, a heightmap or heightfield is a raster image used mainly as Discrete Global Grid in secondary elevation modeling. Each pixel stores values, such as surface elevation data, for display in 3D computer graphics.
Each random value is multiplied by a scale constant, which decreases with each iteration by a factor of 2 −h, where h is a value between 0.0 and 1.0 (lower values produce rougher terrain). [2] During the square steps, points located on the edges of the array will have only three adjacent values set, rather than four.
According to 2007/2/EC European directive, national mapping agencies of European Union countries must have publicly available services for searching, viewing and downloading their official map series. [20] Topographic maps produced by some of them are available under a free license that allows re-use, such as a Creative Commons license. [21]
This will create a grid that with one point in a 2D coordinate will create the same heightmap as it is pseudo-random, meaning it will result in the same output with the same input. This can then easily be translated into the product 3D image. These can then be changed from the editor tools in most engines if the terrain will be custom built.
Supports unlimited terrain size using custom data swapping mechanism to hard disk space. Terrain made of multiple terrain zones supporting variable resolution and automatic border stitching. Procedural heightmap generation using fractal, terracing and erosion tools. Possibility to create and assign multiple layers of heightmaps for each zone.
Upright=1.3STL 3D model of Penang Island terrain based on ASTER Global DEM data. Terrain rendering covers a variety of methods of depicting real-world or imaginary world surfaces. Most common terrain rendering is the depiction of Earth's surface. It is used in various applications to give an observer a frame of reference.

For example, the world's second-highest mountain is K2 (height 8,611 m, prominence 4,017 m). While Mount Everest 's South Summit (height 8,749 m, prominence 11 m [ 2 ] ) is taller than K2, it is not considered an independent mountain because it is a sub-summit of the main summit (which has a height and prominence of 8,848 m).
