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.
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.
A commercial version of the software is also available and is capable of creating larger terrains, renders with higher image resolution, larger terrain files, and better post-render anti-aliasing than the freeware version. The terrain is generated from a two-dimensional heightmap. The program contains facilities for importing and exporting ...
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.
While the primary purpose of picogen is to display realistic 3D terrain, both in terms of terrain formation and image plausibility, it also is a heightmap-creation tool, [1] in which heightmaps are programmed in a syntax reminiscent of Lisp. [2] The shading system is partially programmable. [3]
DTED supports many applications, including line-of-sight analyses, terrain profiling, 3-D terrain visualization, mission planning/rehearsal, and modeling and simulation. DTED is a standard National Geospatial-Intelligence Agency (NGA) product that provides medium resolution, quantitative data in a digital format for military system applications ...
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.
