Details Details

ReflectionTransform gives a TransformationFunction which can be applied to vectors.
ReflectionTransform works in any number of dimensions. In 2D it reflects in a line; in 3D it reflects in a plane.
The point p can lie anywhere in the mirror.

Reflection in the line:

Out[1]=

Out[2]=

Reflection in the plane:

Out[1]=

Out[2]=
