Define an animation

The purpose is to define series of image sequences which define the animation.
All following instructions are executed in the panel ``define animation''.

• Choose the first 3D mesh position with the left mouse button in the drawing area (see section 1.4.5).
• Push on the ``First'' button. The current 3D position is the first position of a sequence of images.
• Define the number of positions (``nb. pos./seq.'') between the first and the last positions in a sequence of images. The default value is a sequence of 5 images.
• Choose the last 3D mesh position in the drawing area.
• Push the ``Last of seq.'' button . The current 3D position is the last position of a sequence of images.
• Then you have defined a sequence of images, the number of positions (``nb. positions'') is updated.
• You can define another sequence of images, on and after the last position of the precedent sequence images; the last precedent position becomes the first one of this new sequence.
• Define the number of positions (``nb. pos. seq.'') between the first and the last positions in this new sequence of images.
• Choose the last 3D mesh position in the drawing area.
• Push the ``Last of seq.'' button .
• Then you have defined two sequences of images, the number of positions (``nb. positions'') is updated (adding the two sequence positions).
  You can of course define others sequences.
• To delete all your animation, click on ``Reset all seq.'' but let's visualize it before.
