#### Parameters

- observer
- Type: ESRI.ArcGISExplorer.Geometry..::.Point

A Point representing the position that you are looking from.

- target
- Type: ESRI.ArcGISExplorer.Geometry..::.Point

A Point representing the location you are looking at.

# Remarks

Use this constructor to store a viewpoint in 3D display mode. Storing a 3D viewpoint relies on two points:

- The observer: the position that you are looking from- where the Z value of the point represents the observers altitude.
- The target: the location you are looking at- a point, usually on the globe surface.
