ReflectionTransform

ReflectionTransform[v]
gives a TransformationFunction that represents a reflection in a mirror through the origin, normal to the vector v.
ReflectionTransform[v, p]
gives a reflection in a mirror through the point p, normal to the vector v.
  • ReflectionTransform works in any number of dimensions. In 2D it reflects in a line; in 3D in a plane.
  • The point p can lie anywhere in the mirror.
