The image is a blackboard with Chinese text written on it. The text reads "2D and 3D Pattern of Stars" and is written in both English and Chinese. Below the text, there is an illustration of a 3D model of a starry night sky. The model is shown in a blue and green color scheme and is surrounded by a white border. 

On the right side of the blackboard, there are two smaller illustrations of the same 3D pattern. The first illustration shows a star with a green background and a blue outline, while the second illustration shows the same star with an orange outline. The illustration is accompanied by text in both Chinese and English.

The background of the image is dark, and there is a large screen on the left side with a colorful design. The screen appears to be displaying information about the 3D patterns of stars.
