Public methodBeginAnimation(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.)
Public methodBeginAnimation(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.)
Public methodCheckAccessDetermines whether the calling thread has access to this DispatcherObject. (Inherited from DispatcherObject.)
Public methodClearValue(DependencyProperty)Clears the local value of a property. The property to be cleared is specified by a DependencyProperty identifier. (Inherited from DependencyObject.)
Public methodClearValue(DependencyPropertyKey)Clears the local value of a read-only property. The property to be cleared is specified by a DependencyPropertyKey. (Inherited from DependencyObject.)
Public methodCloneCreates a modifiable clone of this OrthographicCamera, 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.
Protected methodCloneCoreMakes the instance a clone (deep copy) of the specified Freezable using base (non-animated) property values. (Inherited from Freezable.)
Public methodCloneCurrentValueCreates a modifiable clone of this OrthographicCamera object, making deep copies of this object's current values. Resource references, data bindings, and animations are not copied, but their current values are.
Protected methodCloneCurrentValueCoreMakes the instance a modifiable clone (deep copy) of the specified Freezable using current property values. (Inherited from Freezable.)
Public methodCoerceValueCoerces 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.)

Public methodGetAnimationBaseValueReturns the non-animated value of the specified DependencyProperty. (Inherited from Animatable.)
Public methodGetAsFrozenCreates a frozen copy of the Freezable, using base (non-animated) property values. Because the copy is frozen, any frozen sub-objects are copied by reference. (Inherited from Freezable.)
Protected methodGetAsFrozenCoreMakes the instance a frozen clone of the specified Freezable using base (non-animated) property values. (Inherited from Freezable.)
Public methodGetCurrentValueAsFrozenCreates a frozen copy of the Freezable using current property values. Because the copy is frozen, any frozen sub-objects are copied by reference. (Inherited from Freezable.)
Protected methodGetCurrentValueAsFrozenCoreMakes the current instance a frozen clone of the specified Freezable. If the object has animated dependency properties, their current animated values are copied. (Inherited from Freezable.)
Public methodGetHashCodeGets a hash code for this DependencyObject. (Inherited from DependencyObject.)
Public methodGetLocalValueEnumeratorCreates a specialized enumerator for determining which dependency properties have locally set values on this DependencyObject. (Inherited from DependencyObject.)
Public methodGetTypeGets the Type of the current instance. (Inherited from Object.)
Public methodGetValueReturns the current effective value of a dependency property on this instance of a DependencyObject. (Inherited from DependencyObject.)
Public methodInvalidatePropertyRe-evaluates the effective value for the specified dependency property (Inherited from DependencyObject.)
Protected methodMemberwiseCloneCreates a shallow copy of the current Object. (Inherited from Object.)
Protected methodOnChangedCalled when the current Freezable object is modified. (Inherited from Freezable.)
Protected methodOnFreezablePropertyChanged(DependencyObject, DependencyObject)Ensures that appropriate context pointers are established for a DependencyObjectType data member that has just been set. (Inherited from Freezable.)
Protected methodOnFreezablePropertyChanged(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.)
Protected methodOnPropertyChangedOverrides the DependencyObject implementation of OnPropertyChanged to also invoke any Changed handlers in response to a changing dependency property of type Freezable. (Inherited from Freezable.)
Public methodReadLocalValueReturns the local value of a dependency property, if it exists. (Inherited from DependencyObject.)
Protected methodReadPreambleEnsures that the Freezable is being accessed from a valid thread. Inheritors of Freezable must call this method at the beginning of any API that reads data members that are not dependency properties. (Inherited from Freezable.)
Public methodSetCurrentValueSets the value of a dependency property without changing its value source. (Inherited from DependencyObject.)
Public methodSetValue(DependencyProperty, Object)Sets the local value of a dependency property, specified by its dependency property identifier. (Inherited from DependencyObject.)
Public methodSetValue(DependencyPropertyKey, Object)Sets the local value of a read-only dependency property, specified by the DependencyPropertyKey identifier of the dependency property. (Inherited from DependencyObject.)
Protected methodShouldSerializePropertyReturns a value that indicates whether serialization processes should serialize the value for the provided dependency property. (Inherited from DependencyObject.)
Public methodToString()Creates a string representation of this object based on the current culture settings. (Inherited from Camera.)
Public methodToString(IFormatProvider)Creates a string representation of the Camera. (Inherited from Camera.)
Public methodVerifyAccessEnforces that the calling thread has access to this DispatcherObject. (Inherited from DispatcherObject.)
Protected methodWritePostscriptRaises the Changed event for the Freezable and invokes its OnChanged method. Classes that derive from Freezable should call this method at the end of any API that modifies class members that are not stored as dependency properties. (Inherited from Freezable.)
Protected methodWritePreambleVerifies that the Freezable is not frozen and that it is being accessed from a valid threading context. Freezable inheritors should call this method at the beginning of any API that writes to data members that are not dependency properties. (Inherited from Freezable.)

This class specifies an orthogonal projection of a 3-D model to a 2-D visual surface. Like PerspectiveCamera, it specifies a position, viewing direction, and "upward" direction. Unlike PerspectiveCamera, however, OrthographicCamera describes a projection that does not include perspective foreshortening. In other words, OrthographicCamera describes a viewing box whose sides are parallel, instead of one whose sides meet in a point at the scene's horizon.

The following diagram shows the difference between orthographic and perspective-foreshortened camera projections.

Orthographic and perspective projection

The following example shows how to create an OrthographicCamera and toggle camera projections.


//Toggle between camera projections.
public void ToggleCamera(object sender, EventArgs e)
{
    if ((bool)CameraCheck.IsChecked == true)
    {
        OrthographicCamera myOCamera = new OrthographicCamera(new Point3D(0, 0, -3), new Vector3D(0, 0, 1), new Vector3D(0, 1, 0), 3);
        myViewport.Camera = myOCamera;
    }
    if ((bool)CameraCheck.IsChecked != true)
    {
        PerspectiveCamera myPCamera = new PerspectiveCamera(new Point3D(0, 0, -3), new Vector3D(0, 0, 1), new Vector3D(0, 1, 0), 50);
        myViewport.Camera = myPCamera;
    }
}

How to: Create a 3-D SceneThis example shows how to create a 3-D object that looks like a flat sheet of paper which has been rotated. A Viewport3D along with the following components are used to create this simple 3-D scene:
How to: Animate Camera Position and Direction in a 3D SceneThe following example shows how to animate the position of a camera and animate the direction it is pointing in a 3D scene. This is done by using Point3DAnimation and Vector3DAnimation to animate the Position and LookDirection properties respectively of the PerspectiveCamera. You might use an animation like this to change the onlooker's view of a scene in response to an event.
How to: Animate Camera Position and Direction Using Key FramesIn the following example, Point3DAnimationUsingKeyFrames is used to animate the position of a PerspectiveCamera in a 3D scene. In addition, Vector3DAnimationUsingKeyFrames is used to animate the direction the camera is pointing in the 3D scene. Both of these animations use several key frames which create a series of animation effects:
