Camera 2D

This is what you get when you create a new 2D camera.

Figure 13: Camera 2D menu

In the 2D camera interface, two menus are available: the File menu and the Display menu. A third menu, Objects, let you select the current active object among all the objects present in the 2D scene the camera is looking at.
The Start Computation button let you start the evolution of the scene which effect is to iterate all the Deformable Models of the Scene. If any is present, nothing happens.

• File menu :

  Function	Description
  Load File
  Create Object From File	load a new object which will be created in the camera'scene
  Create Object	shortcut to create new objects depending on the modules loaded
  Iteration Parameters...	settings of time parameters in order to compute the scene evolution
  Record...	make a MPEG movie
  Script Dialog	launch the Scrip Dialog window if not yet present
  Spawn new viewer	create a new camera
  Destroy viewer	destroy the camera

• Display menu :

  Function	Description
  Focus on Scene	reset the point of view to default
  Change Background Color...	set the background color
  Save in a Poscript File...	save the camera view in a postscript file
  Show Bounding Box	show the bounding box
  Hide Bounding Box	hide the bounding box
  Bounding Box Color...	set the bounding box colors
  Bounding Box Width	set the bounding box width

• Objects menu :

  As said before, objects present in a camera can be selected or not. If it's not selected, you are not able to interact with it in the camera (with the mouse).
  Once the object is selected, a menu dedicated to this object appears just under the top menu of the camera.
  This menu offers new functionalities adapted to this kind of object.
  

Example:

Suppose you want to view a 2D contour, saved in a file. You will be able to load it from the 2D camera with the Create Object From File command. Then, after having selected this object in the Objects menu, a new menu associated with the new object appears under the precedent menu.

In the next example, we have loaded two 2D contours. The first one was a square which some vertices have been moved, and the second is the circle around. The Object menu of the 2D camera let choose which 2D contour is the active one. Then, the menu associated with the object let you work with the object you selected. Then, you can performed the disponible operations with the selected object.
