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.
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.
Equirectangular projection of the world; the standard parallel is the equator (plate carrée projection). Equirectangular projection with Tissot's indicatrix of deformation and with the standard parallels lying on the equator True-colour satellite image of Earth in equirectangular projection Height map of planet Earth at 2km per pixel, including oceanic bathymetry information, normalized as 8 ...
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.
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.
Comparison of Bicubic interpolation with some 1- and 2-dimensional interpolations. Black and red / yellow / green / blue dots correspond to the interpolated point and neighbouring samples, respectively.
There are two primary methods to perform bump mapping. The first uses a height map for simulating the surface displacement yielding the modified normal. This is the method invented by Blinn [2] and is usually what is referred to as bump mapping unless specified. The steps of this method are summarized as follows.
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]
