ScalarOccultationDualCone Class |
Provides evaluators for percentage of occultation/eclipse at a position, as well as EclipseType using the dual cone shadow model.
The percentage runs from 0.0 (completely lit) to 1.0 (total eclipse).
This occultation model is much more accurate than ScalarOccultationCylindrical and is the one which should be used in most cases.

The ScalarOccultationDualCone type exposes the following members.
Name | Description | |
---|---|---|
ScalarOccultationDualCone |
Creates a new Scalar with a VectorType of CorrectForLightTimeDelayAndAberration.
IlluminatingBody and TargetPoint must be set before an Evaluator is created,
and generally at least one body should be added to OccludingBodies.
| |
ScalarOccultationDualCone(ScalarOccultationDualCone, CopyContext) | Initializes a new instance as a copy of an existing instance. | |
ScalarOccultationDualCone(CentralBody, Point, CentralBody) |
Creates a new Scalar from the given illuminating body, target point, and occluding bodies.
| |
ScalarOccultationDualCone(CentralBody, Point, IEnumerableCentralBody) |
Creates a new Scalar from the given illuminating body, target point, and occluding bodies.
|
Name | Description | |
---|---|---|
Dimension |
Gets the dimension of the values produced by the object. For example, Vectors
would have a dimension of three, and Scalars of one. A PartialDerivativesEvaluator
created by this type will have a "RowDimension" equal to this
property, and a "ColumnDimension equal to the summation
of the dimensions of the independent variables that this object is dependent on.
| |
IlluminatingBody |
Gets or sets the body to use for the illuminating body (commonly the sun).
(Inherited from ScalarOccultation.) | |
InertialFrame | Gets or sets an alternate inertial reference frame. This property is by default, and if it remains , then the InertialFrame of the IlluminatingBody will be used. The inertial frame is used to correct the position vectors for light time delay and aberration if the appropriate RadiationVectorType is set. | |
IsFrozen |
Gets a value indicating whether this object is frozen. A frozen object cannot be modified and an
ObjectFrozenException will be thrown if an attempt is made to do so.
(Inherited from DefinitionalObject.) | |
OccludingBodies |
Gets a list of bodies which obscure the illuminating body.
(Inherited from ScalarOccultation.) | |
TargetPoint |
Gets or sets the Point representing the location at which
the occultation factor is being calculated.
(Inherited from ScalarOccultation.) | |
VectorType |
Gets or sets whether or not to use true position to calculate the occultation, or apparent position adjusted for aberration.
By default set to CorrectForLightTimeDelayAndAberration.
(Inherited from ScalarOccultation.) |
Name | Description | |
---|---|---|
Add(Double) |
Adds a fixed scalar to this one.
(Inherited from Scalar.) | |
Add(Scalar) |
Adds another scalar to this one.
(Inherited from Scalar.) | |
CalculateEclipseType |
Calculates the type of shadow a platform is in using a dual cone shadow model.
| |
CheckForSameDefinition(DefinitionalObject) |
Checks to determine if another instance has the same definition as this instance and
returns if it does. Derived classes MUST override this method and check
all new fields introduced by the derived class for definitional equivalence. It is NOT necessary
to check base class fields because the base class will already have done that. When overriding this method,
you should NOT call the base implementation because it will return for all derived-class instances.
Derived classes should check the type of other to preserve the symmetric nature of IsSameDefinition(Object).
(Inherited from Scalar.) | |
CheckForSameDefinition(Scalar) |
Checks to determine if another instance has the same definition as this instance and
returns if it does. Derived classes MUST override this method and check
all new fields introduced by the derived class for definitional equivalence. It is NOT necessary
to check base class fields because the base class will already have done that. When overriding this method,
you should NOT call the base implementation because it will return for all derived-class instances.
Derived classes should check the type of other to preserve the symmetric nature of IsSameDefinition(Object).
(Inherited from ScalarOccultation.) | |
CheckForSameDefinition(ScalarOccultation) |
Checks to determine if another instance has the same definition as this instance and
returns if it does. Derived classes MUST override this method and check
all new fields introduced by the derived class for definitional equivalence. It is NOT necessary
to check base class fields because the base class will already have done that. When overriding this method,
you should NOT call the base implementation because it will return for all derived-class instances.
Derived classes should check the type of other to preserve the symmetric nature of IsSameDefinition(Object).
(Overrides ScalarOccultationCheckForSameDefinition(ScalarOccultation).) | |
CheckForSameDefinition(ScalarOccultationDualCone) |
Checks to determine if another instance has the same definition as this instance and
returns if it does. Derived classes MUST override this method and check
all new fields introduced by the derived class for definitional equivalence. It is NOT necessary
to check base class fields because the base class will already have done that. When overriding this method,
you should NOT call the base implementation because it will return for all derived-class instances.
Derived classes should check the type of other to preserve the symmetric nature of IsSameDefinition(Object).
| |
Clone |
Clones this object using the specified context.
(Overrides DefinitionalObjectClone(CopyContext).) | |
ComputeCurrentDefinitionHashCode |
Computes a hash code based on the current properties of this object. Derived classes MUST override this
method and compute a hash code that combines: a unique hash code seed, the base implementation result, and
the hash codes of all new fields introduced by the derived class which are used in the
CheckForSameDefinition(DefinitionalObject) method.
(Overrides ScalarOccultationComputeCurrentDefinitionHashCode.) | |
CreateEvaluatorHelper |
Checks all properties and creates the vectors required to evaluate occultation fractions.
(Inherited from ScalarOccultation.) | |
CreateScalarDerivative |
Constructs a scalar which represents a derivative of this scalar.
(Inherited from Scalar.) | |
Divide(Double) |
Divides this scalar (numerator) by a fixed value (denominator).
(Inherited from Scalar.) | |
Divide(Scalar) |
Divides this scalar (numerator) by another one (denominator).
(Inherited from Scalar.) | |
EnumerateDependencies |
Enumerates the dependencies of this object by calling
EnumerateT(T) for each object that this object directly depends upon.
Derived classes which contain additional dependencies MUST override this method, call the base
implementation, and enumerate dependencies introduced by the derived class.
(Inherited from ScalarOccultation.) | |
Equals | Determines whether the specified object is equal to the current object. (Inherited from Object.) | |
Finalize | Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.) | |
Freeze |
Freezes this object. Further attempts to modify it will result
in an ObjectFrozenException.
(Inherited from DefinitionalObject.) | |
FreezeAggregatedObjects |
Called by Freeze to also freeze any objects that are considered to be a part of this object.
Derived classes which contain additional aggregated objects MUST override this method, call the base
implementation, and freeze aggregated objects introduced by the derived class. The objects that need to be
frozen in this method are frequently created in this object's constructor and are not settable via
properties.
(Inherited from DefinitionalObject.) | |

Gets a hash code representing the definition of this object.
(Inherited from DefinitionalObject.) | |
GetEclipseTypeEvaluators | (Inherited from ScalarOccultation.) | |

(Overrides ScalarGetEvaluator(EvaluatorGroup).) | |
GetHashCode | Serves as the default hash function. (Inherited from Object.) | |
GetPartialDerivativesEvaluator |
This type does not have derivatives or partial derivatives with respect to any object except itself.
Because of that the created PartialDerivativesEvaluator has a
ColumnDimension of zero if this ScalarOccultation
is not in the generalized state, and if it is in the generalized state it returns a 1x1 identity matrix.
| |
GetType | Gets the Type of the current instance. (Inherited from Object.) | |
IsSameDefinition |
Determines if this object has the same definition as another object.
