Whilst the animate button is depressed, any changes made to the parameters in
the scene at a certain frame will be recorded and generate a keyframe. So, lets
give it a go:
- Create a sphere in the front view towards the left hand side:

-
Right Click on your Sphere and choose Properties
from the drop down menu.
-
In the Properties dialog box, Check
the Trajectory Check-Box under Display
Properties.
-
This will enable you to see the path of your animation.
-
Now Click on the Animate Button. It
should turn Red, as should the rim of the active
viewport:



-
This has generated two key frames. It has generated a key frame
at frame 100, specifying the sphere's position as being where we have just
placed it. But it has also guessed that we wanted a key frame at frame 0,
specifying our spheres original position. 3D Studio Max will always
automatically generate this key frame at 0 when you create your first key
frame, unless of course, the first key frame you create is at frame 0!
-
With the Trajectory option on, we
can actually see the key frame at 0 being left behind as we move our sphere
towards the right.
-
Play your animation with the animation
controls (hold your cursor over the buttons to be prompted what they do):

-
We are now going to change the Sphere's position at frame
50 and
generate another keyframe.
-
So, with the animate button still
on, move the Time Slider to frame 50:




Now that we
have 3 keyframes, we need to learn how to edit them. Save your project as ball01, as you
will use it for the next section.
