Member Enumeration Documentation

enum trpgTileTable::TileMode

Tiles can be stored individually (External and ExternalSaved) or in grouped files (Local). ExternalSaved still have an entry in the table. In this case the addess data is not valid.

Enumerator

Member Function Documentation

void trpgTileTable::SetMode

(

TileMode

)

Set the tile storage mode: external or local.

void trpgTileTable::SetNumLod

(

int

numLod

)

Set the total number of LODs For version 2.1 only lod 0 is stored in the table.

void trpgTileTable::SetNumTiles	(	int	numX,
		int	numY,
		int	lod
	)

Set the number of tiles in each dimenion for each terrain LOD This must agree with trpgHeader.

void trpgTileTable::SetTile	(	int	x,
		int	y,
		int	lod,
		trpgwAppAddress &	,
		float32	min,
		float32	max
	)

Set the external address of a given tile as well as its Z value.

bool trpgTileTable::GetMode

(

TileMode &

)

const

Local or external tiles.

bool trpgTileTable::GetTile	(	int	x,
		int	y,
		int	lod,
		trpgwAppAddress &	,
		float32 &	min,
		float32 &	max
	)		const

Get the disk reference (local)

bool trpgTileTable::isValid

(

void

)

const

Validity check.

void trpgTileTable::Reset ( void  )

virtual

Reads this class from a read buffer.

Implements trpgReadWriteable.

bool trpgTileTable::Write ( trpgWriteBuffer &  )

virtual

Writes this class to a write buffer.

Implements trpgReadWriteable.

bool trpgTileTable::Read ( trpgReadBuffer &  )

virtual

Reads this class from a read buffer.

Reimplemented from trpgReadWriteable.

bool trpgTileTable::Print ( trpgPrintBuffer &  ) const

virtual

Prints this class to a print buffer.

Reimplemented from trpgReadWriteable.

void trpgTileTable::SetCurrentBlock ( int  row, int  col, bool  local  )

inline

SetCurrentBlock is used in two cases:

1. When building a block specific tile archive (MMB and non-MMB). (local is TRUE)
2. When merging several blocks into memory for visualization. (local is FALSE)
