Lesson 33: Converting the Trajectory to a Path

To work on the timing and velocity of your sequence, you will convert your trajectory into a single path object.

To convert from Trajectory to path:

1. Switch to Top View.
2. Select your camera by clicking it.
3. Choose Objects menu > Create Path.
   
   A new path object appears, occupying the same space and shape as the camera trajectory.
4. Select the camera again.
5. Click the triangle on the Selection Palette.
6. Choose Camera to select the camera (Notice that there is an option there for selecting paths as well).
   
   The Camera and its trajectory line are selected.
7. Click the Object Attributes button.
8. Click the Linking panel.
9. For Object Parent name, select Path 1 from the pop-up menu of your objects.
10. Click the button next to Constrain to Path.
11. Click the OK icon to leave the dialog box.
    
    The blue trajectory line disappears.
    
    The trajectory line went away when the camera was constrained to the path. All of the key-framed motion information for the camera went away with the trajectory.
    
    The location information of the trajectory is preserved in the path, which is present in your scene.
12. Click the Selection Animation toggle to switch to the Animation palette.
13. Click the Play button. The scrubber moves, but the camera does not.

You'll re-set the key frames for camera motion for the beginning and end of the sequence.
