GeometryTransformerObserveVector Method (Vector, Axes, EvaluatorGroup)

Gets an evaluator that can be used to find the Motion<Cartesian> of this vector in a given axes at a given JulianDate. Note that this will not account for any translational effects and the axes are considered to be the vector's basis. So if the vector is representing a velocity or boresight vector, observing the vector in the axes of a reference frame which is rotating and translating with respect to the vector's axes will only take into account the relative rotation as if the two basis axes were co-located when computing the vector's derivatives. To obtain a vector and its derivatives in a different frame, the vector needs to be created in that frame.

Namespace:  AGI.Foundation.Geometry
Assembly:  AGI.Foundation.Core (in AGI.Foundation.Core.dll) Version: 21.3.411.0 (21.3.411.0)
Syntax
public static VectorEvaluator ObserveVector(
	Vector vector,
	Axes inAxes,
	EvaluatorGroup group
)

Parameters

vector
Type: AGI.Foundation.GeometryVector
The vector to observe.
inAxes
Type: AGI.Foundation.GeometryAxes
The axes in which to observe the vector.
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: VectorEvaluator
An evaluator to find the motion of the vector in the specified axes.
Exceptions
ExceptionCondition
ArgumentNullException Thrown when vector, inAxes, or group is .
