Working with Camera Animations in 2D View

2D View Window

Path edits are clearly distinguished from key frame edits.

This concerns the paths for cameras, lights and objects, as well as the relevant pop-up menus.

Editing Paths

The Camera path is in red.

NB: Camera target points can be edited graphically at any time, regardless of whether the record mode is on or not.

• Use the Edit Path tool in the window bar to select the mode.



• Button pressed: Path editor is active (as a result, the key frame editor is inactive in the view).



• Button released: Key frame editor is active (as a result, the path is visible but cannot be edited).

Example: Creating and Editing a Camera Path

Example: Editing the Camera Target

Creating the Path

• In mode, move the camera viewpoint.

• This draws a red path in a straight line.



• White dots circled in gray indicate the start and end points that have tangents.

• The tangent handles are indicated by red dots circled in black.

Moving the Path

• Click on the path and move it.

Editing the Path

• Use the handles to graphically edit the tangents.



Adding a Control Point

• Right clicking on the red path line and selecting "Add Control Point" displays a gray circle and a tangent with two editing handles.





To Edit a Portion of the Tangent at a Point:

• Right click on the point and select "Unlock Tangent" to create an inflection point on the path.

Example

To Delete the Inflection Point:

• Right click on the point and select "Lock Tangent".

Example: Pausing and Resuming

Example: Forwards and Backwards

Extending the Path

Extends the path without altering the existing animation.

• Alt+Click on the last control point created for the path.

Example

• Creates a new control at the end of the path.

NB: The Timeline can be used to play the sequence at any time.

Path Edit Pop-up Menu

• Right clicking on the red path displays a pop-up menu with the following options:



• Add Control Point: Adds an editable point to the path.

• Delete Control Point: Deletes the point from the path (except the end points).

• Close Path: Closes the path.

• Open Path: Re-opens the path.

• Delete Path: Deletes the path.

Example: Closing a Path

Editing Key Frames

The Camera path is in red.

NB 1: You must be in record mode in order to edit elements in the Timeline.

Example

Key Frame Edit Pop-up Menu

• Add Key Frame: Adds a key frame.

• Remove Key Frame: Deletes a key frame.

Adds a key frame.

• In mode, the button is released (not active).

• In the Timeline window, click on record in 2D view, right click on the path, and select "Add Key Frame" from the pop-up menu.



This creates the key frame.



The key frame can be moved graphically on the path, making it possible to speed up, slow down, etc.

NB: A key frame selected in 2D View appears with a red pin on the Timeline. A pause can be created in the movement of the element by duplicating a key frame in the Timeline.

The 2D View Edit Filters Pop-up Menu

This displays and/or hides paths in order to improve editing in 2D View.

• Right clicking on the white background of the 2D window displays the following pop-up menu, which makes it easier to edit in 2D View, as well as display and hide paths.



• Show All: Displays all camera, light and object paths.

• Show Only Current Type Elements: Depending on which inspector is active (Animations, Lights or Objects), this option displays all camera, light or object paths.

• Show Only Current Element: Displays only the path currently being edited.

Viewpoint Edit Pop-up Menu

Regardless of whether the user is in path or time edit mode, right clicking on a camera's target or one of the blue lines that represent the focus opening will display a pop-up menu with the following options:

• Duplicate: Duplicates the sequence; the current camera position becomes the default view and the path is not duplicated. Uses the original to create a new, superimposed viewpoint.

• Add to: Perspectives View List.

• Add to: Parallel Views List.

• Add to: Panorama List.

• Add to: VR Objects List.

Depending on the option selected, this step adds the current view from Perspectives to Parallel Views, Panoramas or VR Objects.

• Edit Lights Activated With This Viewpoint:
  Choose a light. The inspector palette switches to Lights mode and the light is selected.

• Edit Active Heliodons With This Viewpoint:
  The inspector palette switches to Heliodons mode and the heliodon is selected.

• Delete: The viewpoint is removed from the list.
