An ellipsoidal domain functional returning true inside the ellipsoid. The EllipseDomain represents an ellipsoidal domain which evaluates to true inside the ellipsoid. The ellipsoid can be given a desired center location and radius for each dimension. However, the EllipseDomain does current not support rotation.

The ellipsoid can be constructed with only x,y coordinates and x,y radii. Doing so initialises and ellipsoid at z=0 with infinite radius in the z direction. This mimics a two-dimensional projection and ensures the ellipsoidal domain is constant in z-direction.

Returns true if a point (x, y, z) is contained within the ellipsoid. This evaluates the parametric equation: x^2/a^2 + y^2/b^2 + z^2/c^2 = 1, where the equation is translated to the center of the ellipsoid.
