- Use Primitive Methods to Set Up a Scene
We generally use methods in the programming window to create the animation for the scene. It is also possible to use these methods when building the world and placing objects.
For any object in the scene (including the camera), you can right-click on the object (or the object icon in the top-left window) and select from all available methods for that object. This allows you to precisely move, turn, or roll your object. You can use these methods with respect to other objects as well (e.g., suppose you want to start the scene with two objects facing each other).
- Capture Specific Poses for Later Use
It can be quite difficult to get an object (e.g., person or animal) into the exact pose you need for a scene. Once you go through all of this hard work, it would be nice to be able to save the pose and use it at your convenience.
To save a pose, make sure the object is selected. In the properties tab, there is a "capture pose" button. Capture your pose and give it a meaningful name (e.g., "frogWithLegsExtended").
You can access your pose using the method "set pose". Remember that you can only set a pose that was captured for that particular object. Otherwise you will get an error!
It is also often useful to set a "rest pose", which is the object pose that you will use by default for most of the scene. For example, a human might have a rest pose of standing up with arms at the sides. You might call this "restPose" or "skaterRestPose".
- Capture Specific Camera Positions for Later Use
The top-right window has a button called "more controls >>". Click on this to display extra controls related to the camera.
The "drop dummy at camera" lets you put an invisible camera at the current location. Once you drop a dummy camera, you can name it so you'll remember how it should be used in your scene. All dummy cameras are placed under "Dummy Objects", so you will need to open this icon to rename the dummy camera.
Once you are programming your scene, use the "set point of view to" method and the selected dummy camera to change the scene. You can control the speed with which this happens by setting the delay on the method. A delay of zero will make the camera change instant.

Single View and Quad View
When you are in scene editor mode, the default view is the single view. This is the view from the current location of the camera.
For more detailed work, it is sometimes helpful to switch to quad view. This provides a simultaneous view from the (a) camera view, (b) top of the object, (c) right of the object, and (d) front of the object. These views, when used together, allow for much more precise positioning of the object with respect to other objects.
