ADOBE AFTER EFFECTS 273 Classroom in a Book By applying the motion-control camera data to the camera layer in this composition you have re-created the same movement for the After Effects camera in this composition. As a result you are now able to construct a 3D environment around the actress with accurate perspective. Viewing 3D layers In the world of 3D After Effects what you see in the composition frame is not necessarily how your composition will look. Only Active Camera view accurately displays the image as it will be rendered. The other orthogonal right-angle views show you the relative positions of layers in 3D space as if you were looking at the set of a theatrical production from different points of view overhead off in the stage wings and so forth. What s important in the end is what appears in the camera field of vision what the audience sees. The other views are available simply to help you visualize the relationships among the various layers especially the relationship to the camera.
