| int | Rast3d_read_tile (RASTER3D_Map *map, int tileIndex, void *tile, int type) |
| Reads tile with index tileIndex into the tile buffer. The cells are stored with type type which must be one of FCELL_TYPE and DCELL_TYPE. If the tile with tileIndex is not stored on the file corresponding to map, and tileIndex is a valid index tile is filled with NULL-values. More... | |
| int | Rast3d_read_tile_float (RASTER3D_Map *map, int tileIndex, void *tile) |
| Is equivalent to Rast3d_read_tile (map, tileIndex, tile, FCELL_TYPE). More... | |
| int | Rast3d_read_tile_double (RASTER3D_Map *map, int tileIndex, void *tile) |
| Is equivalent to Rast3d_read_tile (map, tileIndex, tile, DCELL_TYPE). More... | |
| int | Rast3d_lock_tile (RASTER3D_Map *map, int tileIndex) |
| Locks tile with tileIndex in cache. If after locking fewer than the minimum number of unlocked tiles are unlocked, the lock request is ignored. More... | |
| int | Rast3d_unlock_tile (RASTER3D_Map *map, int tileIndex) |
| Unlocks tile with tileIndex. More... | |
| int | Rast3d_unlock_all (RASTER3D_Map *map) |
| Unlocks every tile in cache of map. More... | |
| void | Rast3d_autolock_on (RASTER3D_Map *map) |
| Turns autolock mode on. More... | |
| void | Rast3d_autolock_off (RASTER3D_Map *map) |
| Turns autolock mode Off. More... | |
| void | Rast3d_min_unlocked (RASTER3D_Map *map, int minUnlocked) |
Sets the minimum number of unlocked tiles to minUnlocked. This function should be used in combination with Rast3d_unlock_all () in order to avoid situations where the new minimum is larger than the actual number of unlocked tiles. minUnlocked must be one of RASTER3D_USE_CACHE_X, RASTER3D_USE_CACHE_Y, RASTER3D_USE_CACHE_Z, RASTER3D_USE_CACHE_XY, RASTER3D_USE_CACHE_XZ, RASTER3D_USE_CACHE_YZ, RASTER3D_USE_CACHE_XYZ, the result of Rast3d_cache_size_encode() (cf.{g3d:G3d.cacheSizeEncode}), or any positive integer which explicitly specifies the number of tiles. More... | |
| int | Rast3d_begin_cycle (RASTER3D_Map *map) |
| Starts a new cycle. More... | |
| int | Rast3d_end_cycle (RASTER3D_Map *map) |
| Ends a cycle. More... | |
| void Rast3d_autolock_off | ( | RASTER3D_Map * | map | ) |
Turns autolock mode Off.
