```
    Use spatial predicates as a filter in front of intersection.
    
    Parameters:
    
    a - a geometry
    
    b - a geometry
    
    Returns:
    
    the intersection of the geometries

                                           Geometry b)
```
    Use prepared geometry spatial predicates as a filter in front of intersection, with the first operand prepared.
    
    Parameters:
    
    a - a geometry to prepare
    
    b - a geometry
    
    Returns:
    
    the intersection of the geometries
