Public / Methods

Begin

Begins a new triangulation cycle.

public method	Begin (TriangulationBuffer triangulationBuffer)
params	triangulationBuffer	[not-null]	The output triangulation buffer to use.

SectorLeaf
End

End

Ends the current triangulation cycle.

Begin

Fan

Generates a triangle fan that covers the given mesh sector.

public method	Fan (int32 sector, [] int32[] triangleFanIndices)
type	int32
params	sector		The mesh sector.
	triangleFanIndices	[not-null]	Output array for generated vertex indices.
returns		[6..10]	The number of vertex indices that have been written to triangleFanIndices

Remarks:

Triangle fans can be generated at any time. It is not necessary to call Begin first.

FanLeaf

Generates a triangle fan for a quadrant of the given mesh sector, assuming that it is a leaf (i.e. it has no child sectors).

public method	FanLeaf (int32 sector, int32 childIdx)
type	Vec4I
params	sector		The mesh sector.
	childIdx		Child index of the non-existent sector in sector which area shall be triangulated.
returns			The vertex indices of the triangle fan, to be processed in this order: X, Y, Z, W. The resulting counter-clockwise triangles are thus defined as: <X, Y, Z > <X, Z, W > The second triangle can be degenerated, in which case W will be equal to X. The missing area will then be covered by the triangle fan of an adjacent quadrant.

Remarks:

Triangle fans can be generated at any time. It is not necessary to call Begin first.

Mark

Marks the current end of the triangulation and returns an offset that can be used to render all subsequent triangles.

public method	Mark ()
type	int32
returns		[>=0]	The number of generated vertex indices so far.

Sector

Generates triangles that cover the given mesh sector.

public method	Sector (int32 sector)
params	sector		The mesh sector.

Begin
End

SectorLeaf

Generates triangles that cover a quadrant of the given mesh sector, assuming that it is a leaf (i.e. it has no child sectors).

public method	SectorLeaf (int32 sector, int32 childIdx)
params	sector		Index of center vertex of sector to visit.
	childIdx		Child index of the non-existent sector in sector which area shall be triangulated.
