Model |
This menu item contains: - tools of manual and automatic update of three-dimensional model; - saving the model onto full region; - choice of a projection type and position of the observer concerning the model.
At the first opening of a window of three-dimensional model a creation of 3D-model in sizes of the fragment displayed in a window of a two-dimensional map is carried out. Save on full region - start of creating a 3D-model onto the entire area. For the best representation of 3D-model the customizing of the observer position is used: Observer outside - the observer is on the fixed distance from the landmark. For change of distance from the observer to the landmark the buttons «<» (to distance the model from the observer) and «>» (to approach model to the observer) are used. Turn of model is made concerning the landmark's position. Observer in center - the observer himself moves along model. Turn of model is carried out concerning the observer. Landmark (central index) is in the center of the model and has the form of a red balloon. Disabling the central index is performed in the Options - Additional. The three-dimensional model can be presented in the following projections: Perspective - allows to estimate more really the location of objects relative to each other in a habitual view for the eye. Orthogonal - gives conformity of a three-dimensional view of map's objects to their real sizes, but does not give a perspective view of objects location on model (all is drawn as though in one plane).
