- Derived from
The HeightAboveGround class traverses the filtered mesh (see IMeshFilters.FilterIn) and computes the height of a given point above the terrain surface, along to the up-vector of the terrain geometry (see IGeometry.ComputeUp).
The term above in this context is dependent on the used IGeometry object: points that have a higher elevations value are considered to be above those points with lower elevation values.
The following vertex data semantics are used by this class:
required : Semantic.Position
required : Semantic.Radius
