# class SceneLodGroup

SceneLodGroup is a LOD grouping for the scene graph

# Properties

Property Description
IsFrozen The IsFrozen flag. If set, the node will not be modified by processing modules.
IsModified If set, the node is new, copied, or modified by processing modules. This can be useful to track modifications in the scene graph.
IsVisible The IsVisible flag. If set, the node is visible.
NodeGUID The unique id for this node.
OriginalName The OriginalName parameter which can be used to specify the original name of a node, for debugging of merging purposes. This parameter is not copied or cloned, and is not used internally by Simplygon.

# Methods

Method Description
AddChild Adds a child node to this node. If the child is already a child of another node, it is removed from this node.
CalculateExtents Calculates the axis-aligned bounding box of the node and all its children. If the node tree contains no geometric data, or all data is hidden, the bounding box is not calcluated, and the method returns false.
CreateChildMesh Creates a SceneMesh node as a child node to this node.
CreateChildPlane Creates a ScenePlane node as a child node to this node.
EvaluateDefaultGlobalTransformation Evaluates the default global transformation of the node, regardless of node animation.
FindNamedChild Finds the first child that has the name.
GetChild Get a pointer to the i:th child of this node.
GetChildCount The number of direct children of this node.
GetClass Get the name of the SceneLodGroup class.
GetInf The inferior (minimum) extent of the node.
GetLodForDistance Returns the child node to use for rendering based on the distance parameter and the current threshold values.
GetParent The parent node of this node.
GetPath The path to this node in the scene. Please note that only paths where each node has a name can be used to get to the node using the path.
GetRelativeTransform The relative transformation of this node.
GetScene The scene object of the node.
GetSup The superior (maximum) extent of the node.
GetThresholds The threshold distances associated with the LODs of the LOD group.
HasChild Returns true if the node has the specified child.
IsA Returns true if SceneLodGroup is a or is a descendant of the class named as the type parameter.
IsNull Returns true if the SceneLodGroup object is invalid.
NewClone Clones this node tree (this node and all the descendants of this node) and returns the cloned top node. Please note that the copy is not added to any scene, and can be added anywhere. Also note that the clone shares all data pointers with the original nodes, such as geometry data objects.
NewCopy Deep copies this node tree (this node and all the descendants of this node) and returns the copy top node. Please note that the copy is not added to any scene, and can be added anywhere.
RemoveChild Removes a child from the node.
RemoveChildren Removes all children of this node.
RemoveFromParent Removes this node from its parent.

# Static methods

Method Description
IsClassA Returns true if the class is a or is a descendant of the class named as the type parameter.
SafeCast SafeCast makes sure the input object is of a class that can be cast into spSceneLodGroup, and if this is the case, returns the object cast into spSceneLodGroup.
