return	bool

GetOverlaps() public method

Gets the triangles whose bounding boxes are overlapped by the query.

public GetOverlaps ( BoundingFrustum boundingFrustum, IList outputOverlappedElements ) : bool
boundingFrustum	BoundingFrustum	Shape to query against the tree.
outputOverlappedElements	IList	Indices of triangles in the index buffer with bounding boxes which are overlapped by the query.
return	bool

GetOverlaps() public method

Gets the triangles whose bounding boxes are overlapped by the query.

public GetOverlaps ( BoundingSphere boundingSphere, IList outputOverlappedElements ) : bool

public GetOverlaps ( Microsoft.Xna.Framework.Ray ray, float maximumLength, IList outputOverlappedElements ) : bool
ray	Microsoft.Xna.Framework.Ray	Shape to query against the tree.
maximumLength	float	Maximum length of the ray in units of the ray's length.
outputOverlappedElements	IList	Indices of triangles in the index buffer with bounding boxes which are overlapped by the query.

MeshBoundingBoxTree() public method

Constructs a new tree.

public MeshBoundingBoxTree ( MeshBoundingBoxTreeData data ) : System.Collections.Generic

Refit() public method

Refits the tree based on the current data. This process is cheaper to perform than a reconstruction when the topology of the mesh does not change.

public Refit ( ) : void
return	void

Property Details

LeafMargin public_oe static_oe property

The tiny extra margin added to leaf bounding boxes that allow the volume cost metric to function properly even in degenerate cases.

public static float LeafMargin
return	float
