Create a dense grid representation of a series of values on a grid. This can be used with other functions that operate on a dense grid (such as the SurfaceNets isosurface generators). This function generates the dense grid in ZYX order (the order of the dense grid must match the order required by the consuming function, if any).

• Number spacing - the space between grid points (note that all 3 dimensions must have the same spacing)
• Number begin - table row to begin reading grid points from
• Number end - table row to stop reading grid points at (this row will not be read)
• Function read_point - function that reads the grid location from the table
• Function read_value - function that reads the value at this grid location from the table
• Number borderCells - number of empty 'border' cells to add at the grid extremities (for isosurface generation, you may wish to add one border cell to force surface faces to be generated on the boundary of the grid, if the isosurface intersects the grid boundary).

Determine minimum, maximum points from a series of points in a table. These points define an AABB that contains all of the points in the series (some of which may lie on the boundaries of the AABB).

• Number ↓begin - the first row to read from the table
• Number ↓end - stop reading when we reach this row (this row is not read)
• Function ↓read_point - function to read a point from the table
