Class
     Foam::sampledSurfaces::distanceSurface
 
Description
    A sampledSurface defined by a distance to a surface.
 
    Example:
    \verbatim
    {
        type        distanceSurface;
        surfaceType searchableBox;
        min         (-1 -1 -1);
        max         (1 1 1);
        distance    0.1;
        signed      yes;
        interpolate yes;
    }
    \endverbatim
 
Usage
    \table
        Property     | Description             | Required    | Default value
        surfaceType  | the type of surface to sample from | yes |
        distance     | the distance from which to sample the surface | yes |
        signed       | sample only on one side of the surface, specified by \\
                       the sign of the distance | yes |
        interpolate  | interpolate values to the surface points | no | no
    \endtable
