3d网球：

Are you asking about 3D tennis video games or a type of tennis played in three dimensions? If it's the former, there are many great 3D tennis games available on various gaming platforms that offer a realistic and immersive experience. If it's the latter, I'm not sure if that's a thing, as tennis is typically played on a two-dimensional court. However, there are variations of tennis, such as beach tennis and paddle tennis, that are played on smaller courts and may involve more three-dimensional movement.
