Animation with WebGL and Three.js (5)

Yet another simple case is when I1=I2≠I3. Again from Landau and Lifshitz:

Here is a nice figure from the MIT OpenCourseWare Course.

The simulation parameters are:

Ibody.set(1,0,0, 0,1,0, 0,0,2);
L.set(00, 01, 2.0*Math.PI);

The value of ω in equation (36.6), therefore, becomes pi, while A (=√ Ω1^2 + Ω2^2) becomes 1.0. See the curves of, wx, wy, wz in the graph.
