Ellipsoid Class Reference

Detailed Description

Definition of an ellipsoid.

It is centered on the origin of its canonical frame with its dimensions aligned with the frame's axes. The standard equation for the ellipsoid is:

     x²/a² + y²/b² + z²/c² = 1,

where a,b,c are the lengths of the principal semi-axes of the ellipsoid. The bounding box of the ellipsoid is [-a,a]x[-b,b]x[-c,c].
