    plot2D 制图2D

    The plot2D( ) plots animation on 4 ways:
    1. click the auto-Axis checkbox.
    2. add t into your formula, then click the auto-t checkbox.
    3. add the timer(t) into your formula.
    4. On a device with a keyboard, try selecting one of the sliders and holding down a cursor key to see the patterns evolve continuously.

     4D in the space-time of 4 Dimensions

     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.

     The implicit3D( ) can plot a 4-dimensional (x,y,z,t) object in 3D space, which become animation by clicking the spin checkbox. You manually change the t value by slider.
