about Motion Caputure #1

There are many Motion Capture Systems. Today, I try to introduce the type of motion capture.


1. by Optics
Motion Capture by Optics is the most famous way to get a motion date. Actor's motion is captured by many cameras, and a actor wears special suits for getting motion date.

This way is good for actor's free motion, because the suits that the actor wear is light. But taking capture system by optics is very expensive. Optics camera is needed many, and special studio is required to set cameras.

2.by Magnetic
Motion capture by magnetic is built by magnetic area and censers. This way is good for realizing 3D space that actors play (I've never seen this system, so this item is ambiguity).

This way is not good for actor's movement, because magnetic area that censers can work is very ｓsmall. And the other magnetic things (like towers, antennas..) prevents motion capture from working good.

3. by radio (or Wireless)
Motion capture by wireless machine is constructed by special suits which includes transmitter.

This way is good for getting close actor's date, this way is used for body parts capturing (like only hands, foot or like so). but this style isn't good for getting active date like dance, because transmitters are very heavy.

And there are a few other ways to get motion capture date.
