double VgEngine::VgIViewPoint::mHeading

The viewpoint heading.

double VgEngine::VgIViewPoint::mPitch

The viewpoint pitch.

Note:

In the 2D or 2.5D maps use case, it is usually set to -90.0 degrees to define a vertical, downward view.

VgEngine::VgPosition VgEngine::VgIViewPoint::mPosition

The viewpoint position.

Note:

In the 2D or 2.5D maps use case, in order to provide a comfortable point of view, the mZorAltitude component is computed according to the size of the associated POI, the minimum value being 100.0.

For example, the viewpoint associated to a big supermarket within a mall might have an altitude of 654.3 whereas the one associated to a small kiosk will have an altitude of 100.0.
