Function Documentation

InterceptMissile_Dynamic() [1/4]

template<typename T>

bool YasiuMath::Ballistics::InterceptMissile_Dynamic	(	ProjectileDynamicState< T >	Target,
		const InterceptorParams< T > &	Interceptor,
		const T	MaxQueryTime,
		const T	StepTime,
		const T	AccurateStepTime,
		Types::Vec3< T > &	HitLocation )

Iterative state prediction. Returns first possible intercept location and time.

Accuracy is based on DeltaTime.

Note

There is no iteration limit. Loop is restricted by N = QueryTime / DeltaTime

Suggested Delta range: <0.1 , 1>. Depending on space and distance.

Parameters

Target	State of missile
Interceptor	Params of interceptor
MaxQueryTime	Prediction time to intercept
StepTime	Prediction resolution, how big steps to make. Smaller steps = more steps.
AccurateStepTime	Stepsize used in last phase to determine accurate result, 0=Skip accurate phase
HitLocation	Predicted intercept location

Returns

Flag is solution found estimated intercept location

InterceptMissile_Dynamic() [2/4]

template<typename T>

bool YasiuMath::Ballistics::InterceptMissile_Dynamic	(	ProjectileDynamicState< T >	Target,
		const InterceptorParams< T > &	Interceptor,
		const T	MaxQueryTime,
		const T	StepTime,
		const T	AccurateStepTime,
		Types::Vec3< T > &	HitLocation,
		T &	HitTime )

FULL IMPL.

Iterative state prediction. Returns first possible intercept location and time.

Accuracy is based on StepTime and slightly overshoot position.

AccurateStepTime will iterate positon in last step to evaluate more precise hit. AccurateStepTime=0 will not do better estimation.

Implementation with all arguments.

Note

There is no iteration limit. Loop is restricted by N = QueryTime / DeltaTime

Suggested Delta range: <0.1 , 1>. Depending on space and distance.

Parameters

Target	State of missile
Interceptor	Params of interceptor
MaxQueryTime	Prediction time to intercept
StepTime	Prediction resolution, how big steps to make. Smaller steps = more steps.
AccurateStepTime	SmallStep used to estimate more accurate results
HitLocation	Predicted intercept location
HitTime	Estimated time

Returns

Flag is solution found estimated intercept location

InterceptMissile_Dynamic() [3/4]

template<typename T>

bool YasiuMath::Ballistics::InterceptMissile_Dynamic	(	ProjectileDynamicState< T >	Target,
		const InterceptorParams< T > &	Interceptor,

		Types::Vec3< T > &	HitLocation,
		T &	HitTime )

Iterative state prediction. Returns first possible intercept location and time.

Accuracy is based on DeltaTime.

Return HitTime arguments.

Note

There is no iteration limit. Loop is restricted by N = QueryTime / DeltaTime

Suggested Delta range: <0.1 , 1>. Depending on space and distance.

Parameters
