# 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 with the 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.

Other animated plotters: Polyray, Tracés Animés, Polynomial sweep.
