OdBmSiteSurfaceHelper 

Constructor.
 

addPoints 

Adds points to a topography surface. Returns eInvalidInput if the topography surface already contains a point with the same XY location, otherwise returns eOk.
 

applyToSurface 

detailes Applies changes to the surface 

arePointsEditable 

Returns true if the points of this topography surface can be edited independently. Editing of individual points of the topography surfaces created by facets is prohibited. 

changePointElevation 

Changes the elevation value for a point.
 

changePointsElevation 

Changes the elevation value for points.
 

containsPoint 

Returns true if the given point exists in the topography surface, otherwise false.
 

deletePoints 

Deletes points from a topography surface.
 

findPoints 

Returns only the points of the topography surface which lie within the input bounding box.
 

getBoundaryPoints 

Returns points which are on the boundary of the topography surface. 

getInteriorPoints 

Returns points that are not boundary points for the topography surface. 

getPoints 

Returns points that define this topography surface. 

movePoint 

Moves a point in a topography surface to a new location.
 

movePoints 

Moves points in a topography surface to a new location.
 

setSurface 

Creates a new topography surface element from points.
 

setSurface 

Creates a new topography surface element from points and facets. Points of the topography surface created by facets cannot be modified.
