Orthogonal matrix — In linear algebra, an orthogonal matrix (less commonly called orthonormal matrix[1]), is a square matrix with real entries whose columns and rows are orthogonal unit vectors (i.e., orthonormal vectors). Equivalently, a matrix Q is orthogonal if… … Wikipedia
Orthogonal convex hull — The orthogonal convex hull of a point set In Euclidean geometry, a set is defined to be orthogonally convex if, for every line L that is parallel to one of the axes of the Cartesian coordinate system, the intersection of K with L is empty, a… … Wikipedia
Radical axis — This article is about the radical axis used in geometry. For the animation studio, see Radical Axis (studio). Figure 1. Illustration of the radical axis (red line) of two given circles (solid black). For any point P (blue) on the radical axis, a… … Wikipedia
Principal axis theorem — In the mathematical fields of geometry and linear algebra, a principal axis is a certain line in a Euclidean space associated to an ellipsoid or hyperboloid, generalizing the major and minor axes of an ellipse. The principal axis theorem states… … Wikipedia
Optic axis of a crystal — For the axis of an optical system, see Optical axis. The optic axis of a crystal is the direction in which a ray of transmitted light suffers no birefringence (double refraction). Due to the internal structure of the crystal (the specific… … Wikipedia
Hyperbolic-orthogonal — In mathematics, two points in the Cartesian plane are hyperbolically orthogonal if the slopes of their rays from the origin are reciprocal to one another.If the points are ( x , y ) and ( u , v ), then they are hyperbolically orthogonal if : y /… … Wikipedia
Earth-fixed axis system — this system is a right hand orthogonal axis system fixed on the earth. The trajectory of the vehicle is described with respect to this earth fixed axis system. The x and y axes are in a horizontal plane and the z axis is directed downward … Mechanics glossary

Direct manipulation interface — In computer science, direct manipulation is a human computer interaction style which involves continuous representation of objects of interest, and rapid, reversible, incremental actions and feedback. The intention is to allow a user to directly… … Wikipedia
Rigid rotor — The rigid rotor is a mechanical model that is used to explain rotating systems. An arbitrary rigid rotor is a 3 dimensional rigid object, such as a top. To orient such an object in space three angles are required. A special rigid rotor is the… … Wikipedia
Charts on SO(3) — In mathematics, the special orthogonal group in three dimensions, otherwise known as the rotation group SO(3), is a naturally occurring example of a manifold. The various charts on SO(3) set up rival coordinate systems: in this case there cannot… … Wikipedia
