Terrain Mode:
Defining the Fly Path
Terrain Menu › 3D View › Define Fly Path
Specify the Base surface, the Terrace surface (which
is the translated road cross section surface). The Eye
height, view radius and speed can also be set.
In this example we will be using the road centreline as the fly path, so this
option needs to be selected. From the drop down select the correct road
selected. The fly path can also be graphically inputted.
Click OK to continue.
If any of the surfaces specified are not active in the display settings a dialog
will appear to inform the user. Click Yes to activate the surface.
Viewing the Fly Path
Terrain Menu › 3D View › View
Select the same surfaces as previously selected.
Click OK to continue.
The 3D view of the project will be shown.
Select
AVI output, as shown above if you want the fly through saved as an avi file that
can be viewed in Windows Media Player.
Click Start,
to view the road in 3D.
The road will
now be shown in 3D.
The colour of
the road surface can be changed to make it easier to see the road.
Click on the Material tab
Select Constant colour, and select a different colour for the Base and
Terrace surface
Click Apply to accept the changes.
To view the road in 3D with the new colours, click on the
View tab, and then click on the Start button. |
