The program simulates static magnetic field in 3D using OpenGL. 

User can add wires and pre-defined shapes into the scene thereby 

creating the sources of magnetic field, which is represented by the color (intensity) 

and the small line segments (direction) on the cutting plane. 

Furthermore, the user has the ability to rotate/translate the plane, 

objects and his/her point of view.
