Prior to
my arrival at Carnegie Mellon, an actor had come in and captured a variety of
basic actions, such as cutting a flower and opening a door. All of the actions were done sans props, so
the actor was forced to imagine how one would perform these tasks without the
aid of any outside objects. The data was
already cleaned and processed so it was assigned to me and a few other mentees to import the data onto a model in Maya and animate
the hands using key frame animation. In
order to import the data into Maya, you must first convert it into an AMC
motion file. Once the files are in the
correct form decipherable by Maya, the motion is imported onto the skeleton of
the model. From there the correct
animation settings are chosen and the animation keys are scaled down so that
they will play in real-time. The next
step was to begin animating the hands.
First the existing movement from the motion capture data needed to be
deleted because it was not as accurate as needed for the specific motions that
the actor had performed. Then I went in
and manually set keys that would establish how the hands would move when
animated. To do this accurately, I
performed the actions myself and observed how I held my
hands for
each action. Once the key framing was
done for each hand, the animation was set for rendering followed by being made
into a movie.
