Syntax

Copy

public sealed class MeshObjectNode : ObjectNode, 
	IShadowCastingNode, IShadowReceivingNode, IRayHitTestedObject, IMeshNode

The MeshObjectNode type exposes the following members.

Constructors

	Name	Description
	MeshObjectNode(MeshBase)	Initializes a new instance of the MeshObjectNode class.
	MeshObjectNode(MeshBase, String)	Initializes a new instance of the MeshObjectNode class.
	MeshObjectNode(MeshBase, Material, String)	Initializes a new instance of the MeshObjectNode class.
	MeshObjectNode(MeshBase, Material, String)	Initializes a new instance of the MeshObjectNode class.

Properties

	Name	Description
	IsCastingShadow	Gets or sets a Boolean that specifies if this SceneNode is casing shadow. This means that if IsCastingShadow is true, then 3D objects rendered with this SceneNode will create shadow; if false shadow will not be created. True by default.
	IsReceivingShadow	Gets or sets a Boolean that specifies if this SceneNode can receive shadow - this means that the shadow is rendered on the object(s) rendered by this SceneNode. NOTE: For the shadow to be visible, the effect that is used to render this mesh needs to support rendering shadows. True by default.
	Materials	Gets or sets an array of Material that can be set to override the materials defined in the Mesh.
	Mesh	Gets a Mesh that defines the 3D object geometry.

Methods

	Name	Description
	CollectRenderableObjects	The task of the CollectRenderableObjects method is to create objects derived from RenderablePrimitiveBase and add them to the appropriate RenderingQueue. This method is called at the beginning of RenderScene method call but only when the scene was significantly changed (number of SceneNodes is changed, material is significantly changed, etc.) (Overrides ObjectNodeCollectRenderableObjects)
	GetClosestHitResult	GetClosestHitResult method returns a DXRayHitTestResult with the closest triangle hit by the specified ray. When no triangle is hit, null is returned.
	GetDetailsText	Returns a string with detailed description of this SceneNode. (Overrides ObjectNodeGetDetailsText(Boolean, Boolean, Boolean, Boolean, Boolean))
	GetMesh	Returns the mesh that is used by this SceneNode.
	GetNextHitResult	GetNextHitResult method continues hit testing from the previously returned hit test and returns a DXRayHitTestResult with the next hit triangle (not necessary the next closest triangle) or null if no other triangle is hit. This method can be used to get all hit results.
	Update	Update method is called on each update phase (before render phase) (Overrides SceneNodeUpdate)
	UpdateBounds	Updates the bounds of this SceneNode if the dirty flags indicates that the bounds could be changed of if the forceUpdate parameter is set to true (Overrides SceneNodeUpdateBounds(Boolean))
	UpdateMaterial	UpdateMaterial method needs to be called after a material is changed.
	UpdateMesh	UpdateMesh method needs to be called when the Mesh has been recreated or when SubMeshes data has changed (StartIndexLocation, IndexCount and MaterialIndex do not require regeneration of RenderingQueues). This method updates the RenderableMeshPrimitive that was added to the RenderingQueue.

Fields

	Name	Description
	IsBackFaceMaterial	IsBackFaceMaterial specifies if the material is used to render front (IsBackFaceMaterial == false) or back (IsBackFaceMaterial == true) faces.
	SetOriginalObjectInRenderableMeshPrimitiveToSceneNode	SetOriginalObjectInRenderableMeshPrimitiveToSceneNode is a static Boolean that specifies if the OriginalObject property of the RenderableMeshPrimitive objects that are created by this MeshObjectNode are set to the MeshObjectNode (when true; dy default) or to the Mesh object (when false; as in version 5.0 and before). This allows getting the SceneNode with hit testing.

Extension Methods

	Name	Description
	GetGeometryModel3D	Returns a WPF's GeometryModel3D that was used to create the specified sceneNode. If the sceneNode does not define a GeometryModel3D object, then null is returned. (Defined by Extensions)
	GetModel3D	Returns a WPF's Model3D that was used to create the specified sceneNode. If the sceneNode does not define a Model3D object, then null is returned. (Defined by Extensions)
	GetModelVisual3D	Returns a WPF's ModelVisual3D that was used to create the specified sceneNode or any parent SceneNode (in case searchParentSceneNodes is true). If a SceneNode that defines a ModelVisual3D is not found, then null is returned. (Defined by Extensions)
	GetVisual3D	Returns a WPF's Visual3D that was used to create the specified sceneNode or any parent SceneNode (in case searchParentSceneNodes is true). If a SceneNode that defines a Visual3D is not found, then null is returned. (Defined by Extensions)
