stbox_tile_state_make() STboxGridState * stbox_tile_state_make ( const Temporal *  temp, const STBox *  box, double  size, int64  tunits, POINT3DZ  sorigin, TimestampTz  torigin  ) Create the initial state that persists across multiple calls of the function. Parameters [in] temp Optional temporal point to split [in] box Bounds for generating the multidimensional grid [in] size Tile size for the spatial dimensions in the units of the SRID [in] tunits Tile size for the temporal dimension in PostgreSQL time units [in] sorigin Spatial origin of the tiles [in] torigin Time origin of the tiles Precondition The size argument must be greater to 0. Note The tunits argument may be equal to 0. In that case only the spatial dimension is tiled.
