How to make 3d rotation effect diagram

First, establish the model, then circle the model to be displayed, set virtual objects, select virtual objects, enter the motion panel, select the designated controller, select the position, open the designated controller panel at the upper left, and find the path constraint. At this point, the panel has more path parameters. When adding a path, the virtual object will automatically jump to the path. Then build a camera and bind it to the virtual object. At this time, open the camera's perspective and the animation will be made. Finally, render. Then there is the rotation of the rendering itself. You can set the length of the animation first, then open the timeline and set keyframes. Different key frames can be rotated to different angles, and finally play it to see the rotation effect. After setting, you can output the animation.
