Any object will keep the same shape and size after a proper rigid transformation. All rigid transformations are examples of affine transformations. The set of all (proper and improper) rigid transformations is a mathematical group called the Euclidean group, denoted E(n) for n-dimensional Euclidean spaces. The set of rigid motions is called the ...
The transformations can be applied with a shear matrix or transvection, an elementary matrix that represents the addition of a multiple of one row or column to another. Such a matrix may be derived by taking the identity matrix and replacing one of the zero elements with a non-zero value.
In mathematics, Liouville's theorem, proved by Joseph Liouville in 1850, [1] is a rigidity theorem about conformal mappings in Euclidean space.It states that every smooth conformal mapping on a domain of R n, where n > 2, can be expressed as a composition of translations, similarities, orthogonal transformations and inversions: they are Möbius transformations (in n dimensions).
Reflection. Reflections, or mirror isometries, denoted by F c,v, where c is a point in the plane and v is a unit vector in R 2.(F is for "flip".) have the effect of reflecting the point p in the line L that is perpendicular to v and that passes through c.
The information in this section can be found in. [1] The rigidity matrix can be viewed as a linear transformation from | | to | |.The domain of this transformation is the set of | | column vectors, called velocity or displacements vectors, denoted by ′, and the image is the set of | | edge distortion vectors, denoted by ′.
In mechanics, the dual quaternions are applied as a number system to represent rigid transformations in three dimensions. [1] Since the space of dual quaternions is 8-dimensional and a rigid transformation has six real degrees of freedom, three for translations and three for rotations, dual quaternions obeying two algebraic constraints are used ...
In planar transformations a translation is obtained by reflection in parallel lines, and rotation is obtained by reflection in a pair of intersecting lines. To produce a screw transformation from similar concepts one must use planes in space : the parallel planes must be perpendicular to the screw axis , which is the line of intersection of the ...
Frequently the transformation can be written using vector algebra and linear mapping. A simple example is a turn written as a complex number multiplication: z ↦ ω z {\displaystyle z\mapsto \omega z\ } where ω = cos θ + i sin θ , i 2 = − 1 {\displaystyle \ \omega =\cos \theta +i\sin \theta ,\quad i^{2}=-1} .
