AccessConstraintSamplingGetNextStepFromRelativeMotionEvaluator Method (IServiceProvider, IServiceProvider, Double, EvaluatorGroup)

Gets an evaluator that determines the next time at which to sample a constraint function based on the relative motion between two objects and a maximum relative motion per step.

Namespace:  AGI.Foundation.Access
Assembly:  AGI.Foundation.Core (in AGI.Foundation.Core.dll) Version: 24.3.420.0 (24.3.420.0)
Syntax
Copy
public static Evaluator<JulianDate> GetNextStepFromRelativeMotionEvaluator(
	IServiceProvider observer,
	IServiceProvider target,
	double maximumAngularMotion,
	EvaluatorGroup group
)

Parameters

observer
Type: SystemIServiceProvider
The object that is observing the motion of the target.
target
Type: SystemIServiceProvider
The object whose motion is being observed.
maximumAngularMotion
Type: SystemDouble
The maximum angular motion allowed, in radians.
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: EvaluatorJulianDate
The evaluator.
Exceptions
ExceptionCondition
ServiceNotAvailableException The observer does not provide IKinematicStateService or the target does not provide ILocationPointService.
PropertyInvalidException The observer object's IKinematicStateService has a ReferenceFrame property or the target object's ILocationPointService has a LocationPoint property.
Remarks
In order to determine the next sample time, this evaluator requires that the angular velocity of the target relative to the observer be available. If it is not, the evaluator will return the input time as the next step, indicating that a default step should be taken.
