represents an axis-aligned ellipsoid centered at the point p and with semiaxes lengths ri.

represents an ellipsoid centered at p and weight matrix Σ.


  • Ellipsoid is also known as center interval, ellipse, and hyperellipsoid.
  • Ellipsoid can be used as a geometric region and a graphics primitive.
  • Ellipsoid represents the axis-aligned filled ellipsoid or general ellipsoid .
  • Ellipsoid allows p to be any point in , ri any positive real numbers, and Σ any real symmetric positive definite matrix.
  • Ellipsoid can be used in Graphics and Graphics3D.
  • In graphics, the points p, pi, and radii ri can be Scaled and Dynamic expressions.
  • Graphics rendering is affected by directives such as FaceForm, Specularity, Opacity, and color.
