Terrain View

From the Startup Dialog, to launch with Terrain:

Use the drop-down control to choose from the known terrains.
Use "Edit Properties" to view or edit the properties of the currently chosen terrain (the Terrain Parameters dialog)

Press "OK". The terrain will now load, which may take up to a minute. Messages in the status bar will inform you of the loading progress.

How to Navigate:

Here's a handy guide for using the mouse to navigate in Terrain View.

Menu Commands for Terrain View

File Menu

Layers - Shows the Layers dialog.
Create Layer - open the Create New Layer dialog box
Load Layer - browse for a file (VTST or GIS format) to open as a new layer.
Save Terrain State - When the terrain's parameters have been loaded from a .xml file, this command saves the current state of the terrain back to that .xml file. The state includes the ephemeris, time of day, names of loaded layers, and scenarios.
Save Terrain State As... - Same as Save Terrain State, but saves to a new file.

Tools Menu

		Select - Use the mouse point to move the 3D cursor on the terrain, selecting and deselecting objects. You can also right-click for a pop-up menu of actions for the selected objects. See Working with Culture Objects for more information.
		Select Box - This mode lets you select Abstract Point elements by dragging a box on the screen.
		Select And Move - In addition to selecting objects, you can move them by dragging.
		Move Objects - Similar to the Select and Move mode, except that you can only move objects, so there is no chance of accidentally selecting or deselecting objects you want to move.
		Fences - Opens the Linear Structures dialog for creating features like fences, walls and hedges. Click to add points on the terrain, right-click to close the feature.
		Buildings - Click on the terrain to create buildings. Each click defines a corner of the building footprints, right-click finishes definition.
		Routes - Opens the Routes dialog for creating utility routes, specifically electrical transmission lines.
		Plants - Opens the Plants dialog for creating plants by clicking on the terrain. See Working with Culture Objects for more information.
		Points - Use the mouse to click on the terrain to create labeled points ("placemarks"). The first time you select this mode, it will ask you for the style you want (Color, Size, etc.). The points are generated in a new Abstract Layer, which you can view and save from the Layers Dialog.
		Instances - Opens the Instances dialog for creating 3D model instances by clicking on the terrain.
		Vehicles - Opens the Vehicles dialog for creating vehicle models by clicking on the terrain. Vehicles can be selected, moved and rotated just like instances.
		Navigate - Use the mouse to fly over the terrain. See using the mouse to navigate.
		Measure Distances - Opens the Distance dialog. Drag a line on the terrain to get information about the distance measured several ways.

Scene Menu

Scene Graph - Open the Scene Graph dialog to see the low-level structure of the scene including its engines.
Go to Terrain... - Choose another terrain to switch to.
Go to Space - Switch to Earth View.
Ephemeris - Open the Ephemeris dialog for control of the ocean, sky, fog, background, etc.
Time... - Open the Time dialog.

View Menu

Wireframe - Toggle for wireframe rendering.
Fullscreen - Toggle for fullscreen rendering.
Top-Down Camera - Toggle between the normal camera and a special, orthogonal top-down camera which always looks straight down. In CAD, this is often called 'Plan View'.
Framerate Chart - Toggle showing the current framerate as a little yellow line chart in the lower-left corner of the view.
Elevation Legend - For terrain with texture derived from elevation, show the mapping from elevation values to colors.
Compass - Toggle a small directional compass in the upper-right corner of the view. This shows which way the camera is facing; it is a 'heading' compass.
Overview - Toggle a floating overview map in the lower-left corner of the view. Only works for simple terrain (not tilesets) for which the entire terrain texture is always in memory.
Camera - View Settings - Open the Camera dialog.
Store/Recall Locations - Open the Locations dialog, which also lets you record or load animation paths and play them.
Save Window Snapshot - to JPEG, BMP, PNG, or TIFF.
Save Numbered Snapshot - Same as Save Window Snapshot, but automatically and quietly saves a snapshot to the same filename as before, with an increasing number attached (_000, _001, _002, etc.)
High-resolution Snapshot - Save the window snapshot at a resolution higher than your on-screen window. While this can be larger than your screen, it will only work up to a certain size, determined by your 3D graphics hardware.
Status Bar - Toggle the window's status bar.
Scenarios - Open the Scenarios dialog.
Toolbars - Toggle some toolbar buttons by function. If there are buttons you don't use, you can hide them for a cleaner interface.

Navigate Menu

Fly Slower - Decrease flight speed
Fly Faster - Increase flight speed
Maintain height above ground (toggle) - Keeps the camera at a fixed height above the terrain.
Navigation Style - Choose from several styles of navigation to find one you like. There is also a keyboard shortcut 'D' to toggle the Grab-Pivot navigation.

Terrain Menu

LOD Terrain Surface (toggle) - Show the terrain surface.
Cull every frame (toggle) - Continuously calculates the level of detail needed as the camera moves. You can turn this off to see how the CLOD algorithm is working.
Cull once - When Cull Every Frame is turned off, this tells the CLOD to calculate (cull).
Show Sky (toggle) - The sky (Skydome) is a hemisphere which surround the camera, showing either a static texture, or correct lighting for the time of day (sun, moon, stars, sunrise, sunset).
Show Horizon (toggle) - The horizon is the flat geometry between the edge of the terrain and the far clipping plane.
Show Ocean (toggle) - The ocean plane is an additional flat geometry which intersects the entire terrain, with a watery translucent texture.
Show Plants (toggle) - You can turn all plants (the Vegetation Layer) on and off.
Show Structures (toggle).
Show Roads (toggle).
Show Fog (toggle).
Increase Detail - Increases the detail (triangles or vertices used) of the CLOD terrain surface by 1000. If your terrain is over-simplified, you should increase detail until it looks good.
Decrease Detail - Decreases the detail (triangles or vertices used) of the CLOD terrain surface by 1000.
Level of Detail Info - Shows the Terrain LOD Info dialog with technical information about the CLOD algorithm and (if you are using Tilesets) the texture paging.
Toggle Artificial Foundations - For the current structure layer, each building which lies on a slope has a cement "foundation" level added to elevate it such that no point of the base footprint lies beneath ground level.
Recalculate Shading - If your terrain has shading that was computed at the time the terrain was constructed, then that shading is recalculated. The current time of day is used. This is useful for seeing what a terrain looks like at different times of day.
Change Texture - Opens the Change Texture dialog to let you change the texture on the terrain.
Distribute Vehicles - Puts a number of test vehicles around your road network, where they will will traverse randomly. This is not a real simulation, just a simple test.
