2. Heightmap - Wikipedia

   en.wikipedia.org/wiki/Heightmap

   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.

3. Displacement mapping - Wikipedia

   en.wikipedia.org/wiki/Displacement_mapping

   Displacement mapping is an alternative computer graphics technique in contrast to bump, normal, and parallax mapping, using a texture or height map to cause an effect where the actual geometric position of points over the textured surface are displaced, often along the local surface normal, according to the value the texture function evaluates to at each point on the surface. [1]

4. Scenery generator - Wikipedia

   en.wikipedia.org/wiki/Scenery_generator

   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.

6. Bump mapping - Wikipedia

   en.wikipedia.org/wiki/Bump_mapping

   Look up the height in the heightmap that corresponds to the position on the surface. Calculate the surface normal of the heightmap, typically using the finite difference method. Combine the surface normal from step two with the true ("geometric") surface normal so that the combined normal points in a new direction.

7. Diamond-square algorithm - Wikipedia

   en.wikipedia.org/wiki/Diamond-square_algorithm

   Plasma fractal Animated plasma fractal with color cycling. The diamond-square algorithm is a method for generating heightmaps for computer graphics.It is a slightly better algorithm than the three-dimensional implementation of the midpoint displacement algorithm, which produces two-dimensional landscapes.

8. STL (file format) - Wikipedia

   en.wikipedia.org/wiki/STL_(file_format)

   STL is a file format native to the stereolithography CAD software created by 3D Systems. [3] [4] [5] Chuck Hull, the inventor of stereolithography and 3D Systems’ founder, reports that the file extension is an abbreviation for stereolithography, [6] although it is also referred to as standard triangle language or standard tessellation language.

9. Grome - Wikipedia

   en.wikipedia.org/wiki/Grome

   Procedural heightmap generation using fractal, terracing and erosion tools. Possibility to create and assign multiple layers of heightmaps for each zone. Manual editing of heightmap layers using selection layers and brushes. Flexible brush system that allows custom orientation, mask, strength, directions and pen tablet pressure.
