Public / Attributes

Capacity

Returns the capacity of this object.

public property	Capacity { get }
type	int32
value	[>=0]	The capacity, in elements.
implements	ICapacity.Capacity

HasOverflow

Returns if this triangulation buffer has overflown during the last triangulation process.

public property	HasOverflow { get }
type	bool
value		true if an overflow has occurred, false if not.

Reset

IndexCount

Returns the number of vertex indices that have been generated.

public property	IndexCount { get }
type	int32
value	[>=0]	The number of vertex indices.

Indices

Indices

Returns the array that holds the generated vertex indices.

public property	Indices { get }
type	int32[]
value	[not-null]	The vertex indices array.

IndexCount

Mode

The triangulation mode that has been used to fill this triangulation buffer.

public property	Mode { get set }
type	TriangleMode
value		The triangulation mode.

Remarks:

Defaults to TriangleStrip.

Orientation

The orientation of the triangles in the triangulation buffer.

public property	Orientation { get set }
type	TriangleOrientation
value		The triangle orientation.

Remarks:

Defaults to CounterClockwise.

TriangleCount

Returns the number of triangles that have been generated.

public property	TriangleCount { get }
type	int32
value	[>=0]	The number of triangles.

Remarks:

This count includes degenerated triangles (i.e. triangles with duplicate indices).

ValidTriangleCount

Counts all non-degenerated triangles in this buffer.

public property	ValidTriangleCount { get }
type	int32
value	[>=0]	The number of non-degenerated triangles.

Remarks:

A non-degenerated triangle has three distinct indices.

Public / Constructors

TriangulationBuffer

Creates a new instance of TriangulationBuffer.

public constructor	TriangulationBuffer (int32 capacity = 1048576)
params	capacity	[>0]	The buffer capacity, in indices. Defaults to 1048576.

Public / Methods

Reset

Resets the buffer to a new capacity.

public method	Reset (int32 capacity)
params	capacity	[>0]	The buffer capacity, in indices.

Remarks:

Calling this method will invalidate the current triangulation result (if any).

Update

Updates the given index buffer.

public method	Update (IIndexBuffer buffer, int32 bufferIndex = 0)
type	bool
params	buffer	[not-null]	The index buffer to update.
	bufferIndex	[>=0]	Offset of first index in buffer to write.
returns			true if buffer has been updated, false if the given index buffer has not enough capacity.
