2.4. space curve 3D

Content
  1. Classication by plot function 按制图函数分类:
  2. Classication by appliaction 按应用分类:
    1. Astronomy, chemistry, etc.
    2. plane curve 2D
    3. surface 2D
    4. space curve 3D
    5. surface 3D
    6. surface 4D = hypersurface
  3. Graphics objects
  4. Drawing

A simple straightforward way to run interactive mathematics in a web page is by mathHand.com. All 3D graphes can be zoom, move or spin.

    by wireframe3D(x)

  1. wireframe3D(x)

    by parametric3D(x)

  2. ellipsoid
  3. conjugate-roots

    with 3 parameters and 1 variable t or x

  4. wireframe3D(sin(x),cos(x),x)
  5. parametric3D(cos(t),sin(t),t)
  6. parametric3D(sin(x),cos(x),x)
  7. parametric3D(x,x,x)

    with 2 parameters and 1 variable t or x

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

    by spin3D(x)

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

    Animation

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