Multidimensional geometry refers to the study of geometric objects that exist in more than three dimensions. This field of mathematics is also known as polydimensional geometry, hyperdimensional geometry or n-dimensional geometry. The concept of multidimensionality expands the traditional notions of plane and solid geometry to include higher dimensions that cannot be easily perceived. In addition to its practical applications in computer graphics, scientific modeling and robotics, multidimensional geometry has also played a major role in theoretical physics, particularly in the study of string theory and quantum mechanics. Synonyms for multidimensional geometry include hypergeometry, higher-dimensional geometry, extended geometry and hyperspace geometry.
