Launching GridView
GridView can be accessed in three different ways. The most common way is through the Grid
Manager. The highlighted grid in the Grid Manager will be the master grid in the resulting 3D scene.
You can also access GridView by clicking the GridView button in the Point-to-Point Visibility dialog
box, available from the Point-to-Point Visibility button on the Vertical Mapper toolbar. The advantage
of launching GridView from the Point-to-Point Visibility dialog box is that you can choose the exact
viewpoint locations used in rendering the 3D scene. For more information on the Point-to-Point
Visibility tool, see
The Point-to-Point Visibility Function on page 133
In addition, you can launch GridView by running the Gridview.exe file located in the Vertical Mapper
program folder. Open a grid from the File menu in GridView once the program has initialized.
The master grid is used to decide which other grids can be loaded in the scene and is the grid that all
scene viewing parameters are based on. The distance units used in many of the settings are also
based upon the projection system of the master grid. For example, if the master grid is in a UTM
projection, then the viewing parameters will be in metres.

In the Grid Manager, click the 3D View button and choose the Run 3D Viewer command.
Exploring the Scene Properties Dialog Box
Once GridView has been launched, the 3D Viewer: Scene Properties dialog box appears. This
dialog box contains three tabs: Viewing, Surface and Lighting, and Loaded Grids. A preview window
provides real-time updated views of the rendered grid file, immediately showing the effect of
changing the various settings. Also, the Grid Layer Control helps manage the multiple grids and
drape files that can be rendered within a scene. See
The Grid Layer Control on page 201
.
The Viewing Tab
The Viewing tab enables you to set viewing parameters. It contains settings for determining the view
perspective of a rendered scene.
