hey dyfz, thanx.<br>
<br>
hey andy, heres the problem,<br>
i have a 100 frame video which has a moving camera in it. i have also
been given a sample 3d geometry(few spheres, cubes, a plane etc).&nbsp;
its a matchmoving project. i have to track the 3d camera to the live
action camera in the scene. the way i go about is like this------&gt;<br>
<br>
i create a new matchmove scene in maya live. i load the images in the
image plane of the camera which maya live automatically creates. i
import the 3d geometry into the scene. then i align the image plane of
the camera with the 3d geometry. i have been specifically asked not to
move the geometry. when the geometry exactly matches the image on the
image plane in the first frame, i move ahead to the tracking part.<br>
<br>
i do simple tracking of the camera using the track points. uptil now
everything is fine. then when i move on to solving the camera, the
problem starts.....<br>
after solving i successfully get the exact motion of the 3d camera as
of the live action camera in the scene. but the problem is now after
solving, the camera has moved from the original position&nbsp; and has
taken the starting position which the track points have defined. so the
alignment&nbsp; of the 3d geometry which i matched with the image plane
has also gone haywire.......<br>
now, since i cannot move the geometry and not able to move the camera,
cause its animated, i am stuck. even if i move the camera it goes back
to its original position cause keys has been set during tracking....<br>
<br>
is there anyway i can align the geometry with the image plane after
solving, or am i doing it all wrong, or is there sum options to make
things right which i dont know about????<br>
or my copy of Maya is corrupt????<br>
will u plz let me know ASAP.....<br>
<br>
thanks<br>
