---- ----------
|
|
|
|
SpiceEllipse Structure representing an ellipse in 3-
|
|
dimensional space.
|
|
|
|
The members are:
|
|
|
|
center: Vector defining ellipse's
|
|
center.
|
|
|
|
semiMajor: Vector defining ellipse's
|
|
semi-major axis.
|
|
|
|
semiMinor: Vector defining ellipse's
|
|
semi-minor axis.
|
|
|
|
The ellipse is the set of points
|
|
|
|
{X: X = center
|
|
+ cos(theta) * semiMajor
|
|
+ sin(theta) * semiMinor,
|
|
|
|
theta in [0, 2*Pi) }
|
|
