| Name | Description | |
|---|---|---|
![]() | Bounds | |
![]() | CanFreeze | Gets a value that indicates whether the object can be made unmodifiable. (Inherited from Freezable.) |
![]() | Color | Gets or sets the color of the light. (Inherited from Light.) |
![]() | ConstantAttenuation | Gets or sets a constant value by which the intensity of the light diminishes over distance. |
![]() | DependencyObjectType | Gets the DependencyObjectType that wraps the CLR type of this instance. (Inherited from DependencyObject.) |
![]() | Dispatcher | Gets the Dispatcher this DispatcherObject is associated with. (Inherited from DispatcherObject.) |
![]() | HasAnimatedProperties | Gets a value that indicates whether one or more AnimationClock objects is associated with any of this object's dependency properties.(Inherited from Animatable.) |
![]() | IsFrozen | Gets a value that indicates whether the object is currently modifiable. (Inherited from Freezable.) |
![]() | IsSealed | Gets a value that indicates whether this instance is currently sealed (read-only).(Inherited from DependencyObject.) |
![]() | LinearAttenuation | Gets or sets a value that specifies the linear diminution of the light's intensity over distance. |
![]() | Position | Gets or sets a Point3D that specifies the light's position in world space. |
![]() | QuadraticAttenuation | Gets or sets a value that specifies the diminution of the light's effect over distance, calculated by a quadratic operation. |
![]() | Range | Gets or sets the distance beyond which the light has no effect. |
![]() | Transform | Gets or sets the Transform3D set on the model. (Inherited from Model3D.) |
| Name | Description | |
|---|---|---|
![]() | ApplyAnimationClock(DependencyProperty, AnimationClock) | Applies an AnimationClock to the specified DependencyProperty. If the property is already animated, the SnapshotAndReplace handoff behavior is used.(Inherited from Animatable.) |
![]() | ApplyAnimationClock(DependencyProperty, AnimationClock, HandoffBehavior) | Applies an AnimationClock to the specified DependencyProperty. If the property is already animated, the specified HandoffBehavior is used.(Inherited from Animatable.) |
![]() | BeginAnimation(DependencyProperty, AnimationTimeline) | Applies an animation to the specified DependencyProperty. The animation is started when the next frame is rendered. If the specified property is already animated, the SnapshotAndReplace handoff behavior is used.(Inherited from Animatable.) |
![]() | BeginAnimation(DependencyProperty, AnimationTimeline, HandoffBehavior) | Applies an animation to the specified DependencyProperty. The animation is started when the next frame is rendered. If the specified property is already animated, the specified HandoffBehavior is used. (Inherited from Animatable.) |
![]() | CheckAccess() | Determines whether the calling thread has access to this DispatcherObject.(Inherited from DispatcherObject.) |
![]() | ClearValue(DependencyProperty) | Clears the local value of a property. The property to be cleared is specified by a DependencyProperty identifier. (Inherited from DependencyObject.) |
![]() | ClearValue(DependencyPropertyKey) | Clears the local value of a read-only property. The property to be cleared is specified by a DependencyPropertyKey. (Inherited from DependencyObject.) |
![]() | Clone() | Creates a modifiable clone of this PointLightBase object, making deep copies of this object's values. When copying dependency properties, this method copies resource references and data bindings (but they might no longer resolve) but not animations or their current values. |
![]() | CloneCore(Freezable) | |
![]() | CloneCurrentValue() | Creates a modifiable clone of this ByteAnimationUsingKeyFrames object, making deep copies of this object's current values. Resource references, data bindings, and animations are not copied, but their current values are. |
![]() | CloneCurrentValueCore(Freezable) | |
![]() | CoerceValue(DependencyProperty) | Coerces the value of the specified dependency property. This is accomplished by invoking any CoerceValueCallback function specified in property metadata for the dependency property as it exists on the calling DependencyObject.(Inherited from DependencyObject.) |
![]() | CreateInstance() | |
![]() | CreateInstanceCore() | |
![]() | Equals(Object) | Determines whether a provided DependencyObject is equivalent to the current DependencyObject.(Inherited from DependencyObject.) |
![]() | 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() | |
![]() | FreezeCore(Boolean) | Makes this Animatable object unmodifiable or determines whether it can be made unmodifiable.(Inherited from Animatable.) |
![]() | GetAnimationBaseValue(DependencyProperty) | Returns the non-animated value of the specified DependencyProperty.(Inherited from Animatable.) |
![]() | GetAsFrozen() | |
![]() | GetAsFrozenCore(Freezable) | |
![]() | GetCurrentValueAsFrozen() | |
![]() | GetCurrentValueAsFrozenCore(Freezable) | |
![]() | GetHashCode() | Gets a hash code for this DependencyObject.(Inherited from DependencyObject.) |
![]() | GetLocalValueEnumerator() | Creates a specialized enumerator for determining which dependency properties have locally set values on this DependencyObject. (Inherited from DependencyObject.) |
![]() | GetType() | |
![]() | GetValue(DependencyProperty) | Returns the current effective value of a dependency property on this instance of a DependencyObject. (Inherited from DependencyObject.) |
![]() | InvalidateProperty(DependencyProperty) | Re-evaluates the effective value for the specified dependency property(Inherited from DependencyObject.) |
![]() | MemberwiseClone() | |
![]() | OnChanged() | |
![]() | OnFreezablePropertyChanged(DependencyObject, DependencyObject) | Ensures that appropriate context pointers are established for a DependencyObjectType data member that has just been set.(Inherited from Freezable.) |
![]() | OnFreezablePropertyChanged(DependencyObject, DependencyObject, DependencyProperty) | This member supports the Windows Presentation Foundation (WPF) infrastructure and is not intended to be used directly from your code.(Inherited from Freezable.) |
![]() | OnPropertyChanged(DependencyPropertyChangedEventArgs) | Overrides the DependencyObject implementation of OnPropertyChanged to also invoke any Changed handlers in response to a changing dependency property of type Freezable.(Inherited from Freezable.) |
![]() | ReadLocalValue(DependencyProperty) | Returns the local value of a dependency property, if it exists. (Inherited from DependencyObject.) |
![]() | ReadPreamble() | |
![]() | SetCurrentValue(DependencyProperty, Object) | Sets the value of a dependency property without changing its value source. (Inherited from DependencyObject.) |
![]() | SetValue(DependencyProperty, Object) | Sets the local value of a dependency property, specified by its dependency property identifier. (Inherited from DependencyObject.) |

![]() | ShouldSerializeProperty(DependencyProperty) | Returns a value that indicates whether serialization processes should serialize the value for the provided dependency property.(Inherited from DependencyObject.) |
![]() | ToString() | Creates a string representation of the Model3D. (Inherited from Model3D.) |
![]() | ToString(IFormatProvider) | Creates a string representation of the Model3D. (Inherited from Model3D.) |
![]() | VerifyAccess() | Enforces that the calling thread has access to this DispatcherObject.(Inherited from DispatcherObject.) |
![]() | WritePostscript() | |
![]() | WritePreamble() |
| Name | Description | |
|---|---|---|
