These four buttons on the right side of the 3D View are supposed to fit the view of the generated model in any sight.
It’s possible to move the view, to do a backward or a forward tracking shot, to change the perspective in any position, or to zoom in or out. The main difference between the tracking shot and the zoom is that the zoom doesn’t change the camera position.
While you’re playing around with the buttons, you can realize that the view reacts really sensitive to minor changes. Then the model is gone and it’s hard to get it back in the view.
But the way to achieve this is very simple. The button Fit -> Fit Visible solves the problem. This function is also useful if you execute a bigger model with long branches. After the first simulation, the model often doesn’t fit in the view. The “Fit Visible” button solves the problem so that the model can be shown in its full dimension.
We’re going to simulate this problem by increasing the attribute of the module A which we already did in the second unit. The attribute A controls the length of the branches in the run()-method. After the compilation of the model by the Save Button and the execution by the Run Button, it’s obvious that the view is just showing one long branch. The tracking shot and the zoom aren’t really helpful neither, but one click on Fit -> Fit Visible fits the enlarged model in the complete view.
At the end we’re undoing the alteration and save and compile the model again.
