public int GetNumFileIDs()

Public Function GetNumFileIDs As Integer

public:
int GetNumFileIDs()

member GetNumFileIDs : unit -> int 

Return Value

m_numFileIDs must be initialized the first time getNextTexFront is called.

If the data set has dimension x,y,z, then getNumTileIds represents the number of tiles in a cubic data set of dimension D, where

D = nearest greater power of 2 to max(x,y,z)

(This number varies depending on the topology used). A fileID represents the ID of a tile that is actually used and is 0 if the tile is outside of the actual non cubic data set of dimension x,y,z.

getNumFileIDs returns the number of non null fileIds and is used by the Tile Manager. (It represents the maximum number of non-empty tiles that can be present in main memory.)
