dtNavMeshDataSwapEndian()

bool dtNavMeshDataSwapEndian	(	unsigned char *	data,
		const int	dataSize
	)

Swaps endianness of the tile data.

Warning

This function assumes that the header is in the correct endianness already. Call dtNavMeshHeaderSwapEndian() first on the data if the data is expected to be in wrong endianness to start with. Call dtNavMeshHeaderSwapEndian() after the data has been swapped if converting from native to foreign endianness.

dtNavMeshHeaderSwapEndian()

bool dtNavMeshHeaderSwapEndian	(	unsigned char *	data,
		const int	dataSize
	)

Swaps the endianness of the tile data's header (dtMeshHeader).

Parameters

[in,out]	data	The tile data array.
[in]	dataSize	The size of the data array.

longestAxis()

int longestAxis ( unsigned short  x, unsigned short  y, unsigned short  z  )

inline

subdivide()

static void subdivide ( BVItem *  items, int  nitems, int  imin, int  imax, int &  curNode, dtBVNode *  nodes  )
