Geometric models can be built for objects of any dimension in any geometric space . Both 2D and 3D geometric model s are extensively used in computer graphics. 2D models are important in computer typography and drafting. 3D model s are central to computer-aided design and manufacturing, and many applied technical fields such as geology and medical image processing.

Geometric models are usually distinguished from procedural and object-oriented model s, which define the shape implicitly by an algorithm. They are also contrasted with digital images and volumetric model s; and with implicit mathematical models such as the zero set of an arbitrary polynomial. However, the distinction is often blurred: for instance, geometric shapes can be represented by objects ; a digital image can be interpreted as a collection of colored squareA square as a geometric shape is described and illustrated at square (geometry). There are other concepts derived from it: the geometric unit square; the square units of measurement, such as the square mile, square meter, square kilometer, square inch, ans; and geometric shapes such as circleSee The Circle for the distributed file storage system, and see Ring (diacritic) for the diacritic mark. In Euclidean geometry, a circle is the set of all points in a plane at a fixed distance, called the radius from a fixed point, called the centre .s are defined by implicit mathematical equations. Also, the modeling of fractalA fractal is a geometric object which is "broken up" in a radical way. The term fractal was coined in 1975 by Benoit Mandelbrot, from the Latin fractus or "broken", in order to call attention to such objects. They are in a number of major aspects differen objects often requires a combination of geomtric and procedural techniques.

Geometric isomerismIn chemistry, geometric isomerism is a form of stereoisomerism and describes the orientation of functional groups at the ends of a bond around which no rotation is possible. Such bonds are typically double bonds, but they can also be part of a ring struct Geometric algebraIn mathematics, David Hestenes et al. s geometric algebra [H1999] is a reinterpretation of Clifford algebras over the reals (said to be a return to the original name and interpretation intended by William Clifford). A book of the same title by Emil Artin Geometric meanThe geometric mean of a set of positive data is defined as the product of all the members of the set, raised to a power equal to the reciprocal of the number of members. In a formula: the geometric mean of a a . a is , which is. The geometric mean is usef Geometric distributionIn probability theory and statistics, the geometric distribution is a discrete probability distribution the probability distribution of the number of Bernoulli trials needed to get one success. If the probability of success on each trial is p then the pro Geometric kiteA separate article is about kite flying. In geometry, a kite is a type of quadrilateral, a four-sided polygon. It has two pairs of equal sides, and the two sides in each pair are adjacent. contrast with the parallelogram, where the sides of each pair are Geometric shapeIn geometry, two sets of points are of the same shape precisely if one can be transformed to another by dilating (i. multiplying all distances by the same factor) and then, if necessary, rotating and translating.
