<a id="a139bb19a278626c059c5116b0d4e7cff"></a>## [◆ ](#a139bb19a278626c059c5116b0d4e7cff)DistanceField()

 [DistanceField](class_distance_field.xhtml)  ( ::[Structure](class_structure.xhtml)  *database*,    number  *additional\_space*,    number  *\_grid\_distance*,    size\_t  *max\_approx\_grid\_size*,    bool  *use\_all\_boundary\_faces* = `true`,    bool  *do\_not\_warn* = `false`   ) 

Parameters additional\_spacedefines how much space must be added along each direction of the structure \_grid\_distancedefines the grid point distance max\_approx\_grid\_sizethis is an approximate upper bound to the number of grid points, given that the grid point distance computed from the quantile value exceeds all bounds use\_all\_boundary\_facesif true, then the complete boundary is used. If false, then the boundary is determined by the reference node set do\_not\_warnif true no warning will be created (quiet mode)
