Asymptotic Decider
Encyclopedia
In Scientific Visualization
the Asymptotic Decider is an algorithm developed by Nielson and Hamann in 1991 that creates isosurfaces
from a given scalar field. It was proposed as an improvement to the marching cubes
algorithm, which can produce some "bad" topology, but should better not be seen as an addition to marching cubes, but as an algorithm of its own.
Scientific visualization
Scientific visualization is an interdisciplinary branch of science according to Friendly "primarily concerned with the visualization of three-dimensional phenomena , where the emphasis is on realistic renderings of volumes, surfaces, illumination sources, and so forth, perhaps...

Isosurface
An isosurface is a three-dimensional analog of an isoline. It is a surface that represents points of a constant value within a volume of space; in other words, it is a level set of a continuous function whose domain is 3D-space.Isosurfaces are normally displayed using computer graphics, and are...

Marching cubes
Marching cubes is a computer graphics algorithm, published in the 1987 SIGGRAPH proceedings by Lorensen and Cline, for extracting a polygonal mesh of an isosurface from a three-dimensional scalar field...
