	* Compute the apparent radius of the occulting body from the spacecraft (observer) position. Given a plane containing the spacecraft position, the center of the occulting body (the body shape) and the center of the occulted body, and given a line contained within this plane, passing by the spacecraft position and tangent to the mesh of the occulting body, the apparent radius corresponds to the length of the line starting from the center of the occulting body, perpendicular to the first given line and ending at the intersection of the two lines.		* Compute the apparent radius of the occulting body from the spacecraft (observer) position. Given a plane containing the spacecraft position, the center of the occulting body (the body shape) and the center of the occulted body, and given a line contained within this plane, passing by the spacecraft position and tangent to the mesh of the occulting body, the apparent radius corresponds to the length of the line starting from the center of the occulting body, perpendicular to the first given line and ending at the intersection of the two lines.
	* Compute the apparent radius in a plane containing the spacecraft position, the center of the occulting body and a specified direction instead of the occulted body position. The rest of the behavior stays identical.		* Compute the apparent radius in a plane containing the spacecraft position, the center of the occulting body and a specified direction instead of the occulted body position. The rest of the behavior stays identical.
			* Compute the maximum apparent radius of the body as seen by the spacecraft position. This radius, expressed in meters, corresponds to the maximum distance from the body's center to any point on its surface belonging to the limb ellipse (contour ellipse) viewed by the spacecraft.
	Note: The apparent radius is computed in one direction from the frame origin of the body to the perpendicular tangent line. In case of dissymmetric shape, this definition it might introduce some limitations as the radius computed in the other direction would be different.

	* <code>buildPoint(LLHCoordinatesSystem, double, double, double, String)</code> and similar which return the facet point associated to the specified corrinates in the given LLH coordinates system.		* <code>buildPoint(LLHCoordinatesSystem, double, double, double, String)</code> and similar which return the facet point associated to the specified corrinates in the given LLH coordinates system.
	* <code>getApparentRadius</code> / <code>getApparentRadiusDirection</code> methods which provides the local radius of the body shape seen by an observer in the direction of an occulted body or a specified direction using an approximate iterative algorithm. This method is used by EclipseDetector for instance.		* <code>getApparentRadius</code> / <code>getApparentRadiusDirection</code> methods which provides the local radius of the body shape seen by an observer in the direction of an occulted body or a specified direction using an approximate iterative algorithm. This method is used by EclipseDetector for instance.
			* <code>getMaximumApparentRadius</code> method is not supported by this class (throw an UnsupportedOperationException) as the determination of a contour ellipse won't be possible on this body shape that can define any shape.

	* <code>closestPointTo</code> methods which return the two closest points between the line given in input and the current facet body shape. One of the two points belongs to the line, the other to the facet body shape.		* <code>closestPointTo</code> methods which return the two closest points between the line given in input and the current facet body shape. One of the two points belongs to the line, the other to the facet body shape.
