Public / Attributes

FilterIn

The mesh tree input filter to use for querying sector culling and marks.

public property	FilterIn { get set }
type	MeshTreeFilter
value		The filter or null.
implements	IMeshTraversal.FilterIn

Remarks:

The default value is null (i.e. all mesh sectors are visited).

See also:

MeshTree.GetRoot
MeshTree.GetChild
MeshTree.GetDown

FilterOut

The mesh tree output filter to use for performing sector culling and marking.

public property	FilterOut { get set }
type	MeshTreeFilter
value		The mesh tree filter object.
implements	IMeshTraversal.FilterOut

Remarks:

This MeshTreeFilter is not reset automatically. The application is responsible to call Reset.

The default value is null (i.e. the input filter is used in that case).

MeshTree.SectorMark
MeshTree.SectorMarkRoots

HasMesh

Has this object been bound to an IMesh object?

public property	HasMesh { get }
type	bool
value		true if this object is currently bound to an IMesh, false if not.
inherited	MeshBoundBase.HasMesh

Mesh

The CLOD mesh this object is currently bound to.

public property	Mesh { get }
type	IMesh
value		The CLOD mesh or null.
inherited	MeshBoundBase.Mesh

Tree

The filtered MeshTree of this mesh traversal object.

public property	Tree { get }
type	MeshTree
value	[not-null]	The filtered MeshTree object or null if this object is not bound.
implements	IMeshTraversal.Tree

Public / Methods

MeshBind

Binds this object to the given IMesh.

public override method	MeshBind (IMesh mesh)
params	mesh		The mesh object.
overrides	MeshBoundBase.MeshBind

MeshUnbind

Unbinds this object from its current IMesh.

public virtual method	MeshUnbind ()
inherited	MeshBoundBase.MeshUnbind

VisitFaces

Visits the given mesh root sectors.

public method	VisitFaces (CubemapFace meshFace = CubemapFace.All)
params	meshFace		The mesh face to traverse. Defaults to All.
implements	IMeshTraversal.VisitFaces

VisitQuadrant

Visits a quadrant of the given mesh sector on the current face, assuming that the corresponding child mesh sector does not exist.

public abstract method	VisitQuadrant (int32 sector, int32 childIdx)
params	sector		Index of center vertex of sector to visit.
	childIdx		Index of non-existing child sector in sector.
implements	IMeshTraversal.VisitQuadrant

Remarks:

The quadtree data structure for visiting the given sector can be obtained by getting the Tree property of the current mesh (see MeshBind.

VisitSector

Visits the given mesh sector on the current face.

public abstract method	VisitSector (int32 sector)
params	sector		Index of center vertex of sector to visit.
implements	IMeshTraversal.VisitSector

Remarks:

The quadtree data structure for visiting the given sector can be obtained by getting the Tree property of the current mesh (see MeshBind.
