Creating a Camera Path

- Ignore the new Viewer window that pops up.
- Click the 'constant velocity' button in the Properties frame.
- In the main Viewer window, position the image how you want it to be when you start moving the camera. In the Properties frame, click the add button.
- I like to set this view as the home view so I can come back to it again. In the toolbar above the Viewer frame, click the button that looks like a house with an arrow to set the Home display.
- Next, reposition the image in the Viewer window (pan, zoom, rotate, whatever you want) to how you want it to end. Click the add button again. You should see that the camera path now consists of 2 keyframes.
- If you set the first view as the Home display, you can now return to it. In the toolbar above the Viewer frame, click the button that looks like a house without an arrow. Click the add button again to create your third keyframe.
Adding a Camera Path to a Movie
- In most applications, you will want to apply a camera path after playing through a volume. In this case, you will be starting in Orthographic mode. The mode must be set to Perspective for the camera path to work. Therefore, you will need to add a controller to switch from Orthographic -> Perspective before initiating the camera path, and another controller to switch back from Perspective -> Orthographic after completion of the camera path.
- Select the DemoDirector tab in the Console frame.
- Click the 'New Event' button and select Viewer 0 --> Camera type, then click OK.
- Click on the new Camera event in the DemoDirector frame. Set the start value as Orthographic and the final value as Perspective.
- Now you will need to add the actual CameraPath event. Click 'New Event' and select CameraPath --> Time. Click OK.
- Click on the new Time event in the DemoDirector frame. Set the start and end values. If you set up the CameraPath with 3 keyframes such that keyframe 1 = start, keyframe 2 = middle, keyframe 3 =end/start, you will want to only go from keyframe 1 to keyframe 2. In this case, set the Start time to 0 and the End time to 10.
- Now you need to add another event to switch back to Orthographic mode.
- 'New Event' -> Viewer 0 -> Camera type, start value = Perspective, end value = Orthographic.
