| Name | Description | |
|---|---|---|
![]() | GeometryModel3D() | Creates a new instance of GeometryModel3D. |
![]() | GeometryModel3D(Geometry3D, Material) | Creates a new instance of GeometryModel3D with the specified Geometry3D and Material. |
| Name | Description | |
|---|---|---|
![]() | BackMaterial | Gets or sets the Material used to render the back of this GeometryModel3D. |
![]() | Bounds | |
![]() | CanFreeze | Gets a value that indicates whether the object can be made unmodifiable. (Inherited from Freezable.) |
![]() | 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.) |
![]() | Geometry | Gets or sets the Geometry3D that describes the shape of this GeometryModel3D. |
![]() | 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.) |
![]() | Material | Gets or sets the Material used to render the front of this GeometryModel3D. |
![]() | 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 GeometryModel3D, 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. |
![]() | CloneCurrentValue() | Creates a modifiable clone of this GeometryModel3D object, making deep copies of this object's current values. Resource references, data bindings, and animations are not copied, but their current values are. |
![]() | 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.) |
![]() | Equals(Object) | Determines whether a provided DependencyObject is equivalent to the current DependencyObject.(Inherited from DependencyObject.) |
![]() | Freeze() | |
![]() | GetAnimationBaseValue(DependencyProperty) | Returns the non-animated value of the specified DependencyProperty.(Inherited from Animatable.) |
![]() | GetAsFrozen() | |
![]() | GetCurrentValueAsFrozen() | |
![]() | 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.) |
![]() | ReadLocalValue(DependencyProperty) | Returns the local value of a dependency property, if it exists. (Inherited from DependencyObject.) |
![]() | 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.) |
![]() | 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(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.) |
| Name | Description | |
|---|---|---|
![]() ![]() | BackMaterialProperty | Identifies the BackMaterial dependency property. |
![]() ![]() | GeometryProperty | Identifies the Geometry dependency property. |
![]() ![]() | MaterialProperty | Identifies the Material dependency property. |
| Name | Description | |
|---|---|---|
![]() ![]() | IFormattable.ToString(String, IFormatProvider) | Formats the value of the current instance using the specified format.(Inherited from Model3D.) |
If you need to create a Model3D that uses multiple materials, you must use the Model3DGroup class to combine multiple GeometryModel3D objects.
The front and back sides of the GeometryModel3D are determined by the winding order of the triangles in the MeshGeometry3D. The front side winds counter clockwise.
The Material and BackMaterial properties may be Transparent or null. When the material is transparent, you cannot see that side of the triangle, but hit testing works as usual. When the material is null, you cannot see it, and hit testing does not work.
The following code excerpt creates a GeometryModel3D in the shape of a cube.
<GeometryModel3D> <GeometryModel3D.Geometry> <MeshGeometry3D Positions="-1 -1 0 1 -1 0 -1 1 0 1 1 0" Normals="0 0 1 0 0 1 0 0 1 0 0 1" TextureCoordinates="0 1 1 1 0 0 1 0 " TriangleIndices="0 1 2 1 3 2" /> </GeometryModel3D.Geometry> <GeometryModel3D.Material> <DiffuseMaterial> <DiffuseMaterial.Brush> <SolidColorBrush Color="Cyan" Opacity="0.3"/> </DiffuseMaterial.Brush> </DiffuseMaterial> </GeometryModel3D.Material> <!-- Translate the plane. --> <GeometryModel3D.Transform> <TranslateTransform3D OffsetX="2" OffsetY="0" OffsetZ="-1" > </TranslateTransform3D> </GeometryModel3D.Transform> </GeometryModel3D>
The following code excerpt uses a GeometryModel3D whose Geometry is defined as a static resource.
