Manual Alignment
You can manually align the camera and solved tracker locations if you
like. This technique is most useful for tripod-mode shots; it is generally
better to set up an accurate coordinate system using the methods above for
normal shots.
To align manually, switch to the
3-D control panel
and
the Quad or Quad Perspective view. Click on the camera (typically Camera01) in
one of the viewports to select it, so that it is listed in the dropdown on the
3-D control panel. It will be easiest, though not strictly necessary, to turn
on the selection-lock button
right
underneath the dropdown.
Turn on the
Whole button on the 3-D control panel, then
use the move
,
rotate
,
and scale
tools
to reposition the camera using the viewports. As you do this, not only the
camera will move, but its entire trajectory and the tracker
locations.
By default, meshes will not be carried along, so that you
can import a 3-D model (such as a new building), then reposition the camera and
trackers relative to the building's (fixed) position. However, you can turn on
Whole affects meshes, on the 3-D viewport or perspective-view
right-click menus, and meshes will be moved.
You can use the same technique for moving-object shots, discussed later.
In that case, you will usually click the World button to change to Object
coordinates; you can then re-align the object's coordinate system relative to
the object's trackers (much like you move the pivot point in a 3-D model). As
you do this, the object path will change correspondingly to maintain the
overall match.
