In CG, a keyframe can be set on almost any aspect of an object—its color, position,
size, and so on. Maya then interpolates the in-between frames between the keyframes set
by the animator. In reality, you can set several keyframes on any one frame in CG anima-
tion. Figure 1.6 illustrates a keyframe sequence in Maya.

Figure 1.6
Keyframing. In
the first frame of
this sequence, a
keyframe is set
on the position,
rotation, and scale
of the cone. On
frame 30, the same
properties are
again keyframed.
Maya calculates all
the movement in
between.
