Открытые методы

Метод	Описание
AssignVertexData ( ushort treeDepthStart, ushort treeDepthEnd, ushort resolution, ushort sz ) : void	Assign vertex data to the tree, from a depth and at a given resolution.
CalculateCurrentLod ( Camera cam, float cFactor ) : bool	Calculate appropriate LOD for this node and children
Dispose ( ) : void
FinaliseDeltaValues ( Rectangle rect ) : void	Promote the delta values calculated to the runtime ones (this must be called in the main thread).
GetChild ( ushort child ) : TerrainQuadTreeNode	Get child node
GetLodLevel ( ushort lod ) : LodLevel	Get the LodLevel information for a given lod.
GetSquaredViewDepth ( Camera cam ) : float
GetWorldTransforms ( Matrix4 xform ) : void
Load ( ) : void	Load node and children (perform GPU tasks, will be render thread)
MergeIntoBounds ( long x, long y, Vector3 pos ) : void	Merge a point (relative to terrain node) into the local bounds, and that of children if applicable.
NotifyDelta ( ushort x, ushort y, ushort lod, float delta ) : void	Notify the node (and children) of a height delta value.
PointIntersectsNode ( long x, long y ) : bool	Returns true if the given point is in the terrain area that this node references.
PostDeltaCalculation ( Rectangle rect ) : void	Notify the node (and children) that deltas are going to be calculated for a given range.
PreDeltaCalculation ( Rectangle rect ) : void	Notify the node (and children) that deltas are going to be calculated for a given range.
Prepare ( ) : void	Prepare node and children (perform CPU tasks, may be background thread)
RectContainsNode ( Rectangle rect ) : bool	Returns true if the given rectangle completely contains the terrain area that this node references.
RectIntersectsNode ( Rectangle rect ) : bool	Returns true if the given rectangle overlaps the terrain area that this node references.
ResetBounds ( Rectangle rect ) : void	Reset the bounds of this node and all its children for the region given.
TerrainQuadTreeNode ( Axiom.Components.Terrain.Terrain terrain, TerrainQuadTreeNode parent, ushort xOff, ushort yOff, ushort size, ushort lod, ushort depth, ushort quadrant ) : System	Default constructor.
Unload ( ) : void	Unload node and children (perform GPU tasks, will be render thread)
Unprepare ( ) : void	Unprepare node and children (perform CPU tasks, may be background thread)
UpdateRenderQueue ( RenderQueue queue ) : void
UpdateVertexData ( bool positions, bool deltas, Rectangle rect, bool cpuData ) : void	Tell the node to update its vertex data for a given region.
UseAncestorVertexData ( TerrainQuadTreeNode owner, int treeDepthEnd, int resolution ) : void	Tell a node that it should use an anscestor's vertex data.
VisitRenderables ( bool debugRenderables ) : void
