Terrain Window

Markers

Camera View

The pink lines denotes the camera view - the thick line points in the direction of the target, and the dashed lines show the extent of the horizontal viewing angle (assuming zero bank and pitch)

Objects

Depending on the object distribution type, these are marked by a yellow box, circle or hatched circle. These are only visible when an object is selected in the Object Window.

Trajectory Marker

This small red circle with a red line shows the location and target or the current trajectory point. This is only visible if a trajectory is selected in the Trajectories Window.

Cross hairs

These green dashed lines are for reference purposes only. They show the location where the mouse pointer was last clicked.

Sun Heading

This is marked by the yellow circle and line on the edge of the terrain. This shows the heading of the sun relative to the CENTRE of the terrain - Note that this is not the same as being relative to the camera position marker.

Zooming and Panning

Zooming

To zoom in and out of the terrain hold down the <Shift> key and click the mouse (left button to zoom in, right button to zoom out)

Panning

To centre the terrain on the current pointer location hold down the <Ctrl> key and left-click the mouse.

Parameters

X, Y, (Z), Slope

These boxes show the location and slope angle where the pointer was last clicked over the terrain.

Fix above terrain

When positioning the camera or trajectory points on the terrain it is often useful to set each point slightly above the terrain. This box defines the above of elevation that will automatically be added to (or subtracted from) each location.

Left/Right Mouse click

These option define how the mouse buttons will act when clicking on the terrain:

Camera/Target

Left click sets the camera location. Right click sets the cameras target location.

Object Coord#1/#2

Left click sets the Coord#1 location for the currently selected object (assuming there is one, and the objects window is open). Right click sets the Coord#2 location. Note: the precise use of Coord#1 and Coord#2 depends on the current objects distribution shape. See the Object Window page for more information.

Trajectory Cam/Tar

Left click sets the camera location for the currently selected trajectory point (assuming there is one, and the trajectories window is open). Right click sets the trajectory target point.

Quick Display

When ticked, the terrain will be displayed at low resolution to speed up screen updates.

Altitude

This default option displays the landscape as an altitude map - the higher the elevation, the brighter the pixel.

Slope

This option displays the landscape as a slope map - the steeper the slope, the brighter the pixel.

Contour

This option displays the landscape as a contoured altitude map, which can sometimes be useful to provide an overview of the basic shape of the landscape.

Redraw

This button redraws the current terrain, clearing any 'dirty' pixels (eg from the grass preview)

Reset

This button redraws and resets the default zoom and panning of the terrain.

Pointer Location Info

The four boxes beneath the terrain display information above the current pointer location and zoom factor.

Tips

To identify the slope at any location (without actually setting a Camera, Object or Trajectory point) hold down the <Ctrl> key and click the RIGHT mouse button over the terrain.
