The MaterialGroup type exposes the following members.
| Name | Description | |
|---|---|---|
 | CanFreeze | Gets a value that indicates whether the object can be made unmodifiable. (Inherited from Freezable.) |
| Children | Gets or sets a collection of child Material objects. |
| 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.) |
| 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 | Returns a modifiable copy of the MaterialGroup. |
| CloneCurrentValue | Returns a non-animated version of the MaterialGroup. The returned MaterialGroup represents the current object's state at the time this method was called. |
| CoerceValue | 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.) |
| Equals | Determines whether a provided DependencyObject is equivalent to the current DependencyObject. (Inherited from DependencyObject.) |
| Freeze() | Makes the current object unmodifiable and sets its IsFrozen property to true. (Inherited from Freezable.) |
| GetAnimationBaseValue | Returns the non-animated value of the specified DependencyProperty. (Inherited from Animatable.) |
| GetAsFrozen | Creates 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.) |
| GetCurrentValueAsFrozen | Creates 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.) |
| 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 | Gets the Type of the current instance. (Inherited from Object.) |
| GetValue | Returns the current effective value of a dependency property on this instance of a DependencyObject. (Inherited from DependencyObject.) |
| InvalidateProperty | Re-evaluates the effective value for the specified dependency property (Inherited from DependencyObject.) |
| ReadLocalValue | Returns the local value of a dependency property, if it exists. (Inherited from DependencyObject.) |
| SetCurrentValue | 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.) |
| SetValue(DependencyPropertyKey, Object) | Sets the local value of a read-only dependency property, specified by the DependencyPropertyKey identifier of the dependency property. (Inherited from DependencyObject.) |
| ShouldSerializeProperty | 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 object based on the current culture. (Inherited from Material.) |
| ToString(IFormatProvider) | Creates a string representation of the Material. (Inherited from Material.) |
| VerifyAccess | Enforces that the calling thread has access to this DispatcherObject. (Inherited from DispatcherObject.) |
| Name | Description | |
|---|---|---|
| IFormattable.ToString | Formats the value of the current instance using the specified format. (Inherited from Material.) |
Because DiffuseMaterial, SpecularMaterial, and EmissiveMaterial provide distinctly different effects, it's useful to combine them. For example, you might choose to apply a complex texture to a mesh using DiffuseMaterial, while adding a highlighting effect with a SpecularMaterial on the same mesh. MaterialGroup allows you to treat these Materials as a single texture for convenience.
The following excerpt shows a MaterialGroup.
<MaterialGroup x:Key="LeavesMaterial1"> <DiffuseMaterial> <DiffuseMaterial.Brush> <ImageBrush Stretch="UniformToFill" ImageSource="sample_images\leaves_closeup.png" TileMode="None" ViewportUnits="Absolute" Viewport="0 0 1 1" AlignmentX="Left" AlignmentY="Top" Opacity="1.000000" /> </DiffuseMaterial.Brush> </DiffuseMaterial> <SpecularMaterial SpecularPower="85.3333"> <SpecularMaterial.Brush> <SolidColorBrush Color="#FFFFFF" Opacity="1.000000"/> </SpecularMaterial.Brush> </SpecularMaterial> </MaterialGroup>

| How to: Apply Emissive Material to a 3-D Object | The following example shows how to use EmissiveMaterial to add color to an existing Material equal to the color of the EmissiveMaterial's brush. The code below shows DiffuseMaterial and EmissiveMaterial applied in combination to add blue to the DiffuseMaterial's appearance. |
