### View manager window |  |

The view window allows to set or to edit the projection view for the activated scene or for the calculation results displayed. It is activated from the main tool bar. The input fields in the window depends on the type of projection selected.

Common fields for all projections :

| This a list of all the available projection types. When you change the type of the edited projection, the values of the other fields are reset to their default values. But, if both the previous and the new projections are spherical, then the current values are conserved.
| This menu button gives the history of all the projections applied. It has a limited length (10). When you select a projection from this menu, the fields are filled with the projection data, and the scene is directly rendered using this projection.
Hidden mode : | For all available projections, you can enable or disable the hidden viewing mode.
X-Ray mode : | For all available projections, when in hidden mode you can enable or disable the x-ray viewing option. When enabled, all the surfaces are rendered with transparency.
For plan, parallel and perspective projections only :
Shading mode : | You can enable or disable the shading display mode. When this mode is on, two new fields appear in the bottom of the window : day and time. These fields are used to calculate the sun position and its radiation direction, depending on the latitude value specified in the Settings window.

In the following table, we give the specific required fields, their default values and their values ranges for each projection.

Parallel and Perspective : | Rotation around the Z axis | [0 ... 360 deg]
| Rotation around the X axis | [0 ... 360 deg]
| Scaling factor | [> 0]
All spherical projections : | View point X Y Z fields
| Target point X Y Z fields
| Circle Ray | [> 0 pix]
Solar Paths : | View point X Y Z fields
| Circle Ray | [> 0 pix]
| No target point is needed, because this projection is always a bottom up stereographic projection.

Each time the coordinates of a point are required (view or target point), you can click on the button and choose, using the mouse, the point graphically on the scene displayed in the main view.

Note: These buttons are only activated if the scene is displayed in a plan or parallel projection.

For the target point (if there is any), you can use the button to set a bottom up projection from the view point.

All the keyboard shortcuts available in the main view pane are also available in this window.
