  NameDescription
Public propertyBackMaterialGets or sets the Material used to render the back of this GeometryModel3D.
Public propertyBoundsGets a Rect3D that specifies the axis-aligned bounding box of this Model3D. (Inherited from Model3D.)
Public propertyCanFreezeGets a value that indicates whether the object can be made unmodifiable. (Inherited from Freezable.)
Public propertyDependencyObjectTypeGets the DependencyObjectType that wraps the CLR type of this instance.  (Inherited from DependencyObject.)
Public propertyDispatcherGets the Dispatcher this DispatcherObject is associated with. (Inherited from DispatcherObject.)
Public propertyGeometryGets or sets the Geometry3D that describes the shape of this GeometryModel3D.
Public propertyHasAnimatedPropertiesGets a value that indicates whether one or more AnimationClock objects is associated with any of this object's dependency properties. (Inherited from Animatable.)
Public propertyIsFrozenGets a value that indicates whether the object is currently modifiable. (Inherited from Freezable.)
Public propertyIsSealedGets a value that indicates whether this instance is currently sealed (read-only). (Inherited from DependencyObject.)
Public propertyMaterialGets or sets the Material used to render the front of this GeometryModel3D.
Public propertyTransformGets or sets the Transform3D set on the model. (Inherited from Model3D.)

  NameDescription
Public methodApplyAnimationClock(DependencyProperty, AnimationClock)Applies an AnimationClock to the specified DependencyProperty. If the property is already animated, the SnapshotAndReplace handoff behavior is used. (Inherited from Animatable.)
Public methodApplyAnimationClock(DependencyProperty, AnimationClock, HandoffBehavior)Applies an AnimationClock to the specified DependencyProperty. If the property is already animated, the specified HandoffBehavior is used. (Inherited from Animatable.)
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 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.
Public methodCloneCurrentValueCreates 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.
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 methodEqualsDetermines whether a provided DependencyObject is equivalent to the current DependencyObject. (Inherited from DependencyObject.)
Public methodFreeze()Makes the current object unmodifiable and sets its IsFrozen property to true. (Inherited from Freezable.)
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.)
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.)
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.)
Public methodReadLocalValueReturns the local value of a dependency property, if it exists. (Inherited from DependencyObject.)
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 the Model3D. (Inherited from Model3D.)
Public methodToString(IFormatProvider)Creates a string representation of the Model3D. (Inherited from Model3D.)
Public methodVerifyAccessEnforces that the calling thread has access to this DispatcherObject. (Inherited from DispatcherObject.)

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.

<ModelVisual3D>
  <ModelVisual3D.Content>
    <GeometryModel3D Geometry="{StaticResource myTeapot}">
      <GeometryModel3D.Material>
        <DiffuseMaterial>
          <DiffuseMaterial.Brush>
            <SolidColorBrush Color="Blue" Opacity="1.0" />
          </DiffuseMaterial.Brush>
        </DiffuseMaterial>
      </GeometryModel3D.Material>
      <GeometryModel3D.Transform>
        <RotateTransform3D>
          <RotateTransform3D.Rotation>
            <AxisAngleRotation3D x:Name="myAngleRotation" Axis="0,3,0" Angle="1" />
          </RotateTransform3D.Rotation>
        </RotateTransform3D>
      </GeometryModel3D.Transform>
    </GeometryModel3D>
  </ModelVisual3D.Content>
</ModelVisual3D>
