Rendering of a fractal terrain by ray marching. Ray marching is a family of algorithms, used by ray casting, for finding intersections between a ray and a complex object, such as a volumetric dataset or a surface defined by a signed distance function. It is not, by itself, a rendering method, but it can be incorporated into ray tracing and path ...
In 1978 Jim Blinn described how the normals of a surface could be perturbed to make geometrically flat faces have a detailed appearance. [2] The idea of taking geometric details from a high polygon model was introduced in "Fitting Smooth Surfaces to Dense Polygon Meshes" by Krishnamurthy and Levoy, Proc. SIGGRAPH 1996, [3] where this approach was used for creating displacement maps over nurbs.
Inselberg plain – Isolated, steep rock hill on relatively flat terrain; Lacustrine terrace – A step-like landform; Lava field, also known as lava plain – Large, mostly flat area of lava flows; Oceanic basin – Geologic basin under the sea; Oceanic plateau – Relatively flat submarine region that rises well above the level of the ambient ...

Blender is available for Windows 8.1 and above, and Mac OS X 10.13 and above. [244] [245] Blender 2.80 was the last release that had a version for 32-bit systems (x86). [246] Blender 2.76b was the last supported release for Windows XP, and version 2.63 was the last supported release for PowerPC.
Sediments underlying fluvial terrace exposed in cutbanks along the Manú River, Peru. In geology, a terrace is a step-like landform. A terrace consists of a flat or gently sloping geomorphic surface, called a tread, that is typically bounded on one side by a steeper ascending slope, which is called a "riser" or "scarp".
Terrain (from Latin: terra 'earth'), alternatively relief or topographical relief, is the dimension and shape of a given surface of land. In physical geography , terrain is the lay of the land. This is usually expressed in terms of the elevation , slope , and orientation of terrain features.
A fractal landscape or fractal surface is generated using a stochastic algorithm designed to produce fractal behavior that mimics the appearance of natural terrain. In other words, the surface resulting from the procedure is not a deterministic, but rather a random surface that exhibits fractal behavior.
