‌Camera View Overlay

To see how an inserted object will look, switch to the 3-D control panel. Turn on the Create tool (magic wand). Select one of the built-in mesh types, such as Box or Pyramid. Click and drag in a viewport to drag out an object. Often, two drags will be required, to set first the position and breadth, then a second drag to set the height or overall scale. A good coordinate-system setup will make it easy to place objects. To adjust object size after creating it, switch to the scaling tool . Dragging in the viewport, or using the bottommost spinner, will adjust overall object size. Or, adjust one of the three spinners for each coordinate axis size.

When you are tracking an object and wish to attach a test object onto it (horns onto a head, say), switch the coordinate system button on the 3-D Panel from World to Object.

Note: the camera-view overlay is quick and dirty, not anti-aliased like the final render in your animation package will be (it has “jaggies”), so the overlay appears to have more jitter than it will then. You can sometimes get a better idea by zooming in on the shot and overlay as it plays back (use Pan-To-Follow).

Warning : temporary inserts like this may exhibit large errors if rolling-shutter- compensation is turned on, and there is substantial movement. That is because the insert is not "rolled" to match the source image.

Shortly, we’ll show how to use the Perspective window to navigate around in 3-D, and even render an antialiased preview movie.
