Trajectories Window

Parameters

Trajectory List

Select a trajectory from the List to edit

Rename (...)

Click to rename the current trajectory

New Trajectory

Click to Add a new trajectory

Delete Trajectory

Click to Delete the current trajectory

Import TGS File

Click to import a Terragen Script file to use as a trajectory. This allows animations produced with Terranim or CamPath to be used by Forester

Points List

Click a Point to select it. If the DirectX preview window is locked to Trajectory, then the view will be updated to show this point. (And navigating around the DirectX terrain will automatically update this point).

Point Position, Target, Angle, Zoom

Repective coordinates can be entered manually for more accuracy when required

Speed

This value defines the relative speed at this point. Note 1: The speed setting is only used by the Bezier Interpolation method. Note 2: Consecutive points cannot both have a speed value of zero (it is totally illogical!).

Add Point

Click to add a new point to the trajectory. Note 1: The new point is added after the currently selected point in the trajectory. Note 2: The keyboard shortcut for this button is Alt-A. By repeating pressing Alt-A and the clicking on the Terrain Window, a basic trajectory can be quickly created.

Delete Point

Click to delete the current point.

Height Graph

Click to view a height graph showing the relative height above the terrain of the current trajectory. Note: this is currently only for reference purposes - the height graph window cannot be used to change the height values.

Operations List

Select an operation from the list. The various operations that can be performed are as follows:

Extract Look-At Path

Creates a new trajectory using the current trajectories Target as the Position. Useful when importing Script files to animate an aircraft on the look-at path, whilst the camera follows another path.

Interpolate (Linear)

Linearly interpolates the current trajectory with a larger number of points, thereby increasing its 'resolution'

Interpolate (Bezier - Basic)

Interpolates the current trajectory to have more points using a simple Bezier interpolation method.

Interpolate (Bezier - Constant Speed)

Interpolates the current trajectory to have more points using a Bezier formula. Points are spaced equally along the trajectory

Interpolate (Bezier - Use Speed Setting)

Interpolates the current trajectory to have more points using a complex Bezier formula. Points are spaced according the the speed settings.

Reset All Pitch Values

Sets all Pitch values in the current trajectory to a single value

Reset All Bank Values

Sets all Bank values in the current trajectory to a single value

Reset all Zoom values

Sets all Zoom values in the current trajectory to a single value

Increase All Heights

Adds a constant offset to the height of the current trajectory (can be positive or negative)

Set All Heights relative to Terrain

Sets all points to the terrain altitude at that location (plus an offset value).

Set All Targets to the Succesive Points

Sets the Target of each point to 'look-at' the next point. (ie: always look in the direction of travel)

Set All Targets to the Previous Points

Sets the Target of each point to 'look-at' the previous point. (ie: always looking backforward)

Set Target to 'Look At' Another Trajectory

Sets the Target of each point to 'look-at' a point on a separate trajectory. When using this operation, Forester will cycle through all the other trajectories, asking which one should be used for the look-at path. (Its a bit crude - I shall probably improve this in subsequent versions...) Note that the Look-At trajectory is linearly interpolated if the number of points is not the same as the current trajectory.

Multiply Bank angles by a factor

Multiplies all Bank values by a specifed factor. Use to increase or decrease the overall amount of banking of the current trajectory.
