Vision 4D
    
      --- Introduction ---
    
  
 
Have you ever tried to see objects in dimension 4?
This is possible! Our space is in 3 dimensions. 
  Adding the dimension of time, we get a space-time of dimension 4.
The objects in this space-time are therefore 3D objects 
  which deform withFthe time. following this principle, this tool proposes to you the
  visualization of some of these objects as deforming 3D objects, with the aim
  of helping you to establish this ``vision'' in dimension 4.
Before the module is completed by other objects, you are welcome to our
  list of quadratic hypersurfaces   in ths space-time of dimension 4.
