#3DS – Camera move
5 messages in this thread
I may have missed this somewhere in the book.
I am setting up a camera path to go around an object. That is, start on
the left, go up and above, come down on the right, go down and below and
back to the starting point on the right. That works OK. However, the
result looks like the camera goes up and above then down on the same side,
then down to the bottom and them back up on the same side.
What I want is to have the camera view to go around the object which would
result in the object being upside down when the camera is on the left and
right side up when the camera is on the right. I have tried doing a 180
roll at the left side keyframe. This results in the object 'rotating' as
the camera goes up and over or down and under. I do not want any rotation
of the object.
It's hard to explain these things in words. I hope I have done well enough
for someone to tell me how to do what I want.
Thanks in advance for any help.
Be sure and create your camera in the TOP viewport. Apparently this is how
3D Studio tells the camera where "UP" is.
Paul, I think what you're dealing with is how the camera will automatically
rotate when it's at 90-degrees vertical in the universe. It rotates to
solve the age-old problem of "gimble lock" when completely vertical, and is
one of the major "features" of quaternion rotations (believe it or not).
I've got two suggestions for you. The first one is to never go completely
vertical in your scene. Always undershoot or overshoot the 100% vertical
axis a bit with the camera. The second one is to make a dummy object at
the target position and link the camera to the dummy. You can then rotate
the dummy and control camera rotation more precisely to get the effect you
want. Give them a shot…

Paul,
I haven't tried Gary's second suggestion but when I encountered this I
rotated my objects 90 degrees and rolled my camera 90 degrees. Then the
camera flyby was not over the top but around the side.

I'm not sure if this is feasible in your project, but you could attempt
leaving the camera at a stationary position, and rotating your object(s)
instead.
