Adobe After Effects 5.0- P10272 LESSON 8 Beginning the 3D Composite 2 In the Composition window, select Top view (or press F11) and select 25% (or lower) magnification. The wireframe display represents the view of the camera, including its frame and point of interest, and the camera itself. A row of X’s (so close together they look like a thick black line) illustrates the position keyframes on the pasteboard. A B C A. Point of Interest B. Frame C. Camera 3 On the Time Controls palette, drag the Jog or Shuttle ( ) control to scrub along the timeline, and watch the camera travel along this path. 4 In the Composition window view pop-up menu, select Right view, and then continue scrubbing along the timeline. You can see the camera moving toward the Girl_Alpha.mov layer as it zooms in to the point of interest: the woman’s hands. 5 Select Active Camera view (or press F12) and drag the Jog or Shuttle controls in the Time Controls palette to preview the movement. The view appears to move closer and closer to the actress’s hands. ADOBE AFTER EFFECTS 5.0 273 Classroom in a BookBy applying the motion-control camera data to the camera layer in this composition, youhave re-created the same movement for the After Effects camera in this composition. Asa result, you are now able to construct a 3D environment around the actress with accurateperspective. Viewing 3D layers In the world of 3D After Effects, what you see in the composition frame is not necessarily how your compo- sition 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. As the camera-path views in the previous steps show, the layers are positioned on the pasteboard, far from the composition frame. The position of the layers in relation to the composition frame is somewhat irrelevant. It is possible to reposition your 3D layers within a view so that they fall within the composition frame. You do this by deselecting all layers, setting the view to any except the Active Camera view, and using the track X,Y or the track Z camera tools. The layers appear within the composition frame from the selected point of view. Some layers are represented in full color and others as gray lines, depending on their positions in 3D space.Adding the hexagon layerNext you add the hexagon element, rotating and positioning it in 3D space so that itresembles a platform on which the actress stands.1 Move the current-time marker to 0:00 and set the Composition window magnificationto a convenient level for your monitor size.2 In the Project window, select the Hexagon01.psd file and drag it to the Timelinewindow so that it is Layer 1 in the layer stack.3 In the Switches panel, click the 3D layer switch ( ) to make the hexagons a 3D layer.The layer disappears in the Composition window.274 LESSON 8 Beginning the 3D Composite 4 In the Composition window, select Top view (or press F11), and notice where the Hexagon01.psd layer is in relation to the camera. To see this, click the Camera 1 layer to see its path (the condensed line of X’s), and then click the Hexagon01.psd layer to see its layer handles. Layer 1 is behind the camera, so it does not appear in Active Camera view. 5 Move the pointer over the blue Z-axis arrow of the Hexagon01.psd layer so that the pointer appears with a small Z. Drag the layer toward the top of the Composition window so that it is positioned in front of (above) the camera. If necessary, reduce the magnifi- cation even further (choose View > Zoom Out) to see the pasteboard as you do this. A B A. Camera B. Hexagon01.psd layer ADOBE AFTER EFFECTS 5.0 275 ...
