LSBOOL LSE_CALL lsg::CTriangleStripper::Compute

(

)

Create the triangle strip. After a successful call to this function, the created triangle strip can be read directly.

Returns:

Returns true if there were no memory failures during the operation.

LSBOOL LSE_CALL lsg::CTriangleStripper::ConnectStrip	(	CVectorPoD< LSUINT32, LSUINT32, 1024UL > &	_vLeft,
		LSUINT32 *	_pui32Right,
		LSUINT32	_ui32RightLen
	)		[protected]

Connect one strip to another.

Parameters:

_vLeft	The first strip to connect to the second.
_pui32Right	Second strip to connect.
_ui32RightLen	Length of the second strip to connect.

Returns:

Returns false if there was not enough memory to perform the operation.

LSUINT32 LSE_CALL lsg::CTriangleStripper::GetBestStrip	(	LSUINT32	_ui32Face,
		LSUINT32 *	_pui32TempFaceBuffer,
		LSUINT32 *	_pui32BestFaceBuffer,
		LSUINT32 *	_pui32TempStripBuffer,
		LSUINT32 *	_pui32BestStripBuffer,
		LSUINT8 *	_pui8TempTagsBuffer,
		LSUINT8 *	_pui8Tags,
		LSUINT32 &	_ui32StripLen
	)		[protected]

Determine the best strip starting at the given face.

Parameters:

_ui32Face	The face where to start searching.
_pui32TempFaceBuffer	Buffer to hold faces for checking strip lengths.
_pui32BestFaceBuffer	Best face buffer found. Output.
_pui32TempStripBuffer	Buffer to hold strips for checking strip lengths.
_pui32BestStripBuffer	Best strip buffer found. Output.
_pui8TempTagsBuffer	Buffer to hold tags for checking strip lengths.
_pui8Tags	The master copy of the tags buffer. Updated with the longest strip's details.
_ui32StripLen	The length of the longest strip. Output.

Returns:

Returns the number of faces in the strip.

LSUINT32 LSE_CALL lsg::CTriangleStripper::GetStripLength	(	LSUINT32	_ui32Face,
		LSUINT32	_ui32Oldest,
		LSUINT32	_ui32Middle,
		LSUINT32 *	_pui32Strip,
		LSUINT32 *	_pui32Faces,
		LSUINT8 *	_pui8Tags
	)		[protected]

Get the length of a triangle if extended from the given face in the given direction.

Parameters:

_ui32Face	Index of the face where to start checking.
_ui32Oldest	First index of the strip.
_ui32Middle	Second index of the strip.
_pui32Strip	Buffer in which to store the strip.
_pui32Faces	Buffer in which to store the faces.
_pui8Tags	Buffer to use to keep track of tagged faces.

Returns:

Returns the length of the strip.

LSE_INLINE const LSUINT32 *LSE_CALL lsg::CTriangleStripper::IndicesAsDoubleWords

(

)

const

Get the indices as a double-word size.

Returns:

Returns the indices as a double-word size.

LSE_INLINE const LSUINT16 *LSE_CALL lsg::CTriangleStripper::IndicesAsWords

(

)

const

Get the indices as a word size.

Returns:

Returns the indices as a word size.

LSBOOL LSE_CALL lsg::CTriangleStripper::InitTriangleStripper	(	LSUINT32	_ui32Faces = 0UL,
		const LSUINT32 *	_pui32Faces = NULL,
		const LSUINT16 *	_pui16Faces = NULL
	)

Initialize the triangle stripper.

Parameters:

_ui32Faces	Number of triangles.
_pui32Faces	Pointer to the triangles with 32-bit indices or NULL.
_pui16Faces	Pointer to the triangles with 16-bit indices or NULL.

Returns:

Returns false if there are not enough resources to complete the setup.

LSE_INLINE LSUINT32 LSE_CALL lsg::CTriangleStripper::TotalIndices

(

)

const

Get the total indices.

Returns:

Returns the total indices.
