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)
Syntax
public static PointEvaluator ObservePoint(
	Point point,
	ReferenceFrame inFrame,
	EvaluatorGroup group
)

Parameters

point
Type: AGI.Foundation.GeometryPoint
The point to observe.
inFrame
Type: AGI.Foundation.GeometryReferenceFrame
The reference frame in which to observe the point.
group
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.
Exceptions
ExceptionCondition
ArgumentNullException Thrown when point, inFrame, or group is .
