Description

This method returns a set of objects (ppHits) hit by the line of sight from the observer location and the window coordinates xView, yView in pViewer. 

If bGetLocation=True, it indicates that the hit point coordinates must be returned. 
If both bGetLocation and bGetTransformed are True, it indicates that the returned coordinates must be in the internal geocentric coordinate system. If bGetTransformed=False, the returned hit point coordinates are in the Globe Spatial Reference: longitude, latitude and altitude in kilometers.
If bGetEmptyGlobe is True, a hit will be added for the base globe surface, even if it doesn't contain any layer.
If bFeaturesOnly is True, only hits to features will be returned (hits to elevation surfaces will not).
