Figure 3.51 Applying a motion tween to each layer
Exercise Summary
This exercise reflects how our mind interprets 3D space. In Chapter 2, we discussed
how our stereoscopic vision creates two separate images that our mind merges into a
single three-dimensional image. The resulting image allows us to perceive depth and
estimate distance. A distant object, such as the moon in the sky, is so far away that our
eyes produce essentially the same image, making depth imperceptible. That is why the
sky with the moon is not scaled.
Continue to experiment with the file. Add more keyframes later in time. Increase the
scale and position of each layer and apply motion tweens. To see a completed version
of the exercise, open 3_6_depthIllusion_DONE.fla in the Completed_Exercises
folder in Chapter 3.
