Concepts of 3D and animation
3D,
The 3d effect can only be seen through long-distance observation. Because the distance is too close, we can only see the 2d effect of the plane. Therefore, we need to set the depth of field before setting the 3d transformation effect:
perspective: 1200px; /* Use in the parent element to set the depth of field*/
At the same time, we ...

Basic lighting in Unity
Generally speaking, we need to consider three physical phenomena to simulate the real lighting environment to generate an image.
First, light is emitted from the light source.
Then, the light intersects with some objects in the scene: some light is absorbed by the object, while others are scattered in other directions.
Finally, the camera ab ...
