Space curve

by parametric3D(x)

1. ellipsoid
2. conjugate-roots

   3 equations with 1 variable t or x

3. Cabello's Curve 曲线
4. parametric3D(cos(t),sin(t),t)
5. parametric3D(sin(x),cos(x),x)
6. parametric3D(x,x,x)

   2 equations with 1 variable t or x

   the 2D curve becomes 3D by clicking the 3D checkbox
7. parametric3D(x,x)
8. complex sn(x) Curve

   by wireframe3D(x)

9. wireframe3D(x)
10. wireframe3D(sin(x),cos(x),x)

    by spin3D(x)

    spin different directions by clicking the spin checkbox.
11. spin3D(x**2)

    Animation

    The parametric3D( ) plots animation by clicking the spin checkbox.
    
12. A space cubic curve. Most simple, but only its movement shows what it is about.
    
13. A Lissajous figure with rotating phase.
    
14. The above Lissajous figure is a projection of this space curve.
    
15. Another space curve, a little bit more complicated: hyperbolic spiral.
