3D animation uses computer virtual simulation technology to create realistic animations. Researchers focused on character modeling and animation using skeletal animation algorithms. They created 3D human animations by adding bones and skinning meshes. Real motion data from motion capture technology was used to drive character movements. The study found that skeletal animation produced good results, with basic actions successfully completed. Adding artificial intelligence elements improved the naturalness and realism of the animations. This research has practical applications for creating lifelike virtual characters.
