Lisajoue Figures

Lisajoue figures are curves with the parametric equations x = sin at, y = cos bt, z = sin ct. Twiddle these figures by dragging with the mouse.

3d Java applet: cylinder.

a=5, b=9, c=9. You get a cylinder if b=c or b=a.

3d Java applet: tetrahedron.

a=5, b=9, c=4. You get a tetrahedron-like object if b=a+c.
