It’s been a shorter week but nonetheless full of tons of work to
do. Due to the problems that developed
last week, these last few days my primary focus has been with the motion
capture data that is being used for Professor Duesing’s animation. Sadly at first I continued to run into the
same problem repeatedly, you’d think I would have learned after the first time…The
motion could not be imported onto the skeleton of the characters that had been
built. The initial thought was that the
motion data itself was flawed. To check
this I simply took an old model that I knew had successfully been used with
motion capture data and applied the new character motion to it. It worked perfectly. From there began basic trial and error. I was eventually able to apply the motion to
the correct character by transferring the old skeleton which held the motion to
the model. The problem with this
however, was that there was then a glitch in the leg data where the character’s
legs would twist around as it walked. I
had a meeting with my mentor towards the end of the week and mentioned the
problem that I was having to her. It was
suggested that I try retargeting the motion between skeletons. I did a little research on the subject and
basically what retargeting entails is that the motions and key frames from one
skeleton are reapplied to the skeleton of a different character. As long as the joint names of both skeletons
align to some degree, there should be no problem in transferring the
motion. After playing around with the
settings I was finally able to successfully place the motion capture data onto
the characters! It was an exciting
moment, plus I was able to show Professor Duessing, who was satisfied with the
work. In addition to working with the
motion capture data for the art project, I continued working on the swirling
objects scene. For some reason I had
difficulty replicating the work I had been doing, which does not help in the
long run, so I had to retrace my steps somewhat and fix a few glitches within
the process of my work. Eventually
though, I was able to create an emitter of flowers and animals from a central
point around the character which spun around his head during the specific
portion of the scene. The particles of
geometry, such as flowers and leaves, are slightly less restrained along their
path curves so the next step I will be taking is to adjust the motion settings
to more effectively control their movement.
