GeometryTransformerObservePoint Method (Point, ReferenceFrame, EvaluatorGroup)

Gets an evaluator that can be used to find the Motion<Cartesian> of this point in the new ReferenceFrame at a given JulianDate. The motion will also express any derivatives in the new frame if requested.

Namespace:  AGI.Foundation.Geometry
Assembly:  AGI.Foundation.Core (in AGI.Foundation.Core.dll) Version: 18.4.397.0 (18.4.397.0)
public static PointEvaluator ObservePoint(
	Point point,
	ReferenceFrame inFrame,
	EvaluatorGroup group


Type: AGI.Foundation.GeometryPoint
The point to observe.
Type: AGI.Foundation.GeometryReferenceFrame
The reference frame in which to observe the point.
Type: AGI.FoundationEvaluatorGroup
The group with which to associate the new evaluator. By grouping evaluators that are often evaluated at the same Julian dates, common computations can be performed only once for the entire group instead of multiple times for each evaluator.

Return Value

Type: PointEvaluator
An evaluator to find the motion of the point in the specified reference frame.
ArgumentNullException Thrown when point, inFrame, or group is .
