To put it bluntly, motion capture is to stick the instrument contact to the real person. After sticking them on the joints, the instrument can record the motion trajectories of real joints and contacts. These are all motion capture data, and then the motion capture data is imported into maya, and the motion curve is adjusted and interspersed, so that the animation can be completed efficiently. For example, when a person runs and jumps, it will take a lot of time to use K animation in Keyshot mode, which may be distorted, but it is much more convenient to use motion capture to find a real person to run and jump and then export the data. This is a way for foreigners to make animation in batches, which is relatively seldom used by domestic enterprises.
