In reflection in a point, each point P of the set S of all points of unextended space is carried into the point P1 of S such that PP1 is bisected by a fixed point O of space.

In reflection in a line, each point P of S is carried into the point P1 of S such that PP1 is perpendicularly bisected by a fixed line l of space.

In reflection in a plane, each point P of S is carried into the point P1 of S such that PP1 is perpendicularly bisected by a fixed plane p of space.

For a detailed description of the object created Q, use the routine detail (i.e., detail(Q))

The command with(geom3d,reflection) allows the use of the abbreviated form of this command.

Warning, assume that the name of the axes are _x, _y and _z
