	Name	Description
	Scene(String)	Creates Scene object without a VulkanDevice. Before rendering the Scene, it needs to be initialized by calling Initialize(VulkanDevice) method.
	Scene(VulkanDevice, String)	Creates Scene object and provides a VulkanDevice.

	Name	Description
	BackgroundRenderingLayer	Gets a RenderingLayer that is rendered first. Objects in this layer are not sorted and are rendered in the same order as they are added to the layer.
	BackgroundSpritesRenderingLayer	Gets a RenderingLayer that contains sprites that are rendered before any other 3D object is rendered. This RenderingLayer is not added to RenderingLayers collection but is rendered in RenderSpritesRenderingStep.
	ComplexGeometryRenderingLayer	Gets a RenderingLayer that contains opaque and very complex 3D objects that are expected to take a lot of GPU time to render and should therefore start rendering as soon as possible. Usually this layer contains instanced objects, big point cloud objects or standard objects with many triangles. Objects in this layer are not sorted and are rendered in the main thread (no multi-threading rendering) and in the same order as they are added to the layer.
	DirtyFlags	Gets the dirty flags for this Scene. This value is reset to None when calling Update(Boolean) method.
	EffectsManager	Gets the EffectsManager
	ForegroundRenderingLayer	Gets a RenderingLayer that is rendered after standard GeometryRenderingLayer but before TransparentRenderingLayer. Objects in this layer are not sorted and are rendered in the same order as they are added to the layer.
	GpuDevice	VulkanDevice that was used to initialized this Scene.
	HitTestOptions	HitTestOptions specifies hit testing parameters that are used with hit testing.
	IsDefaultCoordinateSystem	Gets true when the default coordinate system (YUpRightHanded) is used.
	IsMaterialSortingEnabled	Gets or sets a Boolean that specified if sorting objects by their materials is enabled. Sorting objects usually improves rendering performance because objects with same materials are rendered one after another and this reduces the required DirectX state changes. Objects are sorted by their material hash value only when they are in the MaterialSortedRenderingLayer (usually all standard and opaque geometry objects). But sometimes user wants to have full control of the order in which the objects are sorted. In this case it is possible to disable material sorting. Default value is true.
	IsRightHandedCoordinateSystem	Gets true when the coordinate system is right handed (YUpRightHanded or ZUpRightHanded).
	IsTransparencySortingEnabled	Gets or sets a Boolean that specifies if sorting transparent objects by their distance to the camera is enabled. Default value is false. See remarks for more info.
	Lights	Gets a collection of all scene lights.
	LightsCount	Gets the number of non-ambient lights that are defined in the scene.
	LineGeometryRenderingLayer	Gets a RenderingLayer that contains opaque and single-colored 3D line objects that are rendered with ThickLineEffect. Objects in this layer are not sorted but are rendered with using multi-threading.
	LineRasterizationMode	Gets or sets the mode that specifies how the 3D lines are rendered. By default this value is set to GeometryShader. This is the recommended mode because it is supported on most platforms, is the fastest and provides the most customizations. This value needs to be set before the default ThickLineEffect is initialized.
	MaxLightsCount	Gets or sets the maximum number of lights that can be rendered.
	OtherGeometryRenderingLayer	Gets a RenderingLayer that contains opaque objects that cannot be rendered with StandardEffect. Usually this layer contains pixels, objects with physically based rendering material and other objects with non-standard effect (for example vertex colored materials). The objects in this layer are not rendered with using multi-threading. Objects in this layer are sorted so that they are grouped by material to minimize state changes.
	OverlayRenderingLayer	Gets a RenderingLayer that is rendered last. Objects in this layer are not sorted and are rendered in the same order as they are added to the layer.
	OverlaySpritesRenderingLayer	Gets a RenderingLayer that contains sprites that are rendered after 3D objects are rendered. This RenderingLayer is not added to RenderingLayers collection but is rendered in RenderSpritesRenderingStep.
	RenderingItemsPool	Gets the ObjectPool to get RenderingItem objects.
	RenderingLayers	RenderingLayers is a read only collection of rendering layers that represent queues of RenderingItems that are prepared to be rendered in the FillCommandBufferRenderingStep. RenderingLayer are rendered in the same order as in the RenderingLayers list.
	RootNode	RootNode defines the root GroupNode that contains the SceneNode objects that are shown by this Scene.
	StandardGeometryRenderingLayer	Gets a RenderingLayer that contains standard opaque objects that can be rendered with StandardEffect (all objects with StandardMaterial or objects that are created from WPF 3D objects). Objects in this layer are sorted so that they are grouped by material to minimize state changes and are also rendered with using multi-threading.
	SwapChainImagesCount	Gets the number of swap chain images count
	TransparentRenderingLayer	Gets a RenderingLayer that contains transparent objects. Objects in this layer are sorted by their distance to the camera - farthest objects are rendered first.

	Name	Description
	AddAnimation	Adds the specified animation to the list of animations that are updated in each update phase.
	AddRenderingLayerAfter	Adds the newRenderLayer after the already registered afterRenderLayer. If rendering layer is MaterialSortedRenderingLayer or CameraDistanceSortedRenderingLayer, then also its IsSortingEnabled property is set according to the current settings.
	AddRenderingLayerBefore	Adds the newRenderLayer before the already registered afterRenderLayer
	CacheObject	CacheObject sets the specified objectToCache to the specified key in the cache. The value can be retrieved by GetCachedObjectT(String) or removed by RemoveCachedObject(String) method. When a Mesh object is cached, this will set IsSceneCached to true and prevent disposing the mesh (by calling Dispose method) before the Scene is disposed or before the mesh is removed from the cache. Mesh and GpuImage objects can be cached only in one Scene object. This method is thread safe and can be called from any thread.
	Cleanup	Cleanup method can perform various cleanup actions. It can dispose the SceneNodes (and their meshes and materials) that were removed from the RootNode. It can dispose GPU resources that were scheduled to be disposed after a frame has been rendered. It can also check all memory blocks and free those that are empty (if freeEmptyMemoryBlocks is true or when it empty for at least EngineRuntimeOptions.FramesCountToReleaseEmptyMemoryBlock frames).
	CollectAmbientLightColor	CollectAmbientLightColor returns a Color3 that specifies the ambient color (can be combined by multiple AmbientLight objects).
	CreateBackgroundSpriteBatch	Creates a SpriteBatch that will be rendered before the objects in this Scene are rendered. SpriteBatch that is created from Scene object can use only relative coordinates. To use absolute coordinates, call SceneView.CreateBackgroundSpriteBatch(String) or SceneView.CreateOverlaySpriteBatch(String) methods. To remove the created SpriteBatch call the RemoveSpriteBatch(SpriteBatch, Boolean) or RemoveAllSpriteBatches(Boolean) methods. It is also possible to add sprites that are rendered only with a specific SceneView - in this case call SceneView.CreateBackgroundSpriteBatch(String) or SceneView.CreateOverlaySpriteBatch(String) methods.
	CreateOverlaySpriteBatch	Creates a SpriteBatch that will be rendered after the objects in this Scene are rendered. SpriteBatch that is created from Scene object can use only relative coordinates. To use absolute coordinates, call SceneView.CreateBackgroundSpriteBatch(String) or SceneView.CreateOverlaySpriteBatch(String) methods. To remove the created SpriteBatch call the RemoveSpriteBatch(SpriteBatch, Boolean) or RemoveAllSpriteBatches(Boolean) methods. It is also possible to add sprites that are rendered only with a specific SceneView - in this case call SceneView.CreateBackgroundSpriteBatch(String) or SceneView.CreateOverlaySpriteBatch(String) methods.
