Creating a 3D terrain view
A 3D terrain view lets you view the ground surface of a network that has a ground model loaded on its GeoPlan window.
To create a 3D Terrain View:
- Open a network in the GeoPlan Window and optionally load a ground model that covers the area of interest.
- Load background layers and set up themes to be displayed in the 3D Terrain View window
- Centre the GeoPlan over the point of interest, zoom in or out, and if needed resize the view until you get exactly the area you want to display in the 3D Terrain View window.
- Choose New 3D Terrain Window from the Window menu. A new 3D Terrain View window is opened with the same size and extents as the GeoPlan.
- The centre point is defined as the centre of the view at ground height. Ground height is interpolated or extrapolated if needed.
- The initial position of the viewpoint is directly above the centre point, and far enough away to show the full extents of the view.
- The 3D terrain view assumes the position of the light source (sun) to be that defined in the hill shading properties of the GeoPlan window. If the settings are not appropriate, you will need to adjust these for the GeoPlan and then create a new 3D terrain view.
If the number of network objects in the current GeoPlan window is greater than 1000, the option of whether or not to include network objects in the 3D Terrain View window is given. Including a large number of network objects may result in slow performance.
