How is the special effect of the neutron bomb passing through the air achieved in The Matrix?

When the director first thought of this idea, he decided to make this special effect unrepeatable.

Surround camera structure is to surround dozens of cameras with the same style around the scene, and then each camera shoots separately and post-produces. Each camera only keeps one or two frames (24 frames per second), which is the surround effect of bullets passing through the air. Then through CG technology, it is enough to edit the picture of bullets passing through the air. To know that the cost and complexity of this structure far exceed the average level, even ten years later, few people are willing to try it.

What is more worth mentioning is the high-speed car chase scene. If you look carefully, you will find that his car chase scene is different from the general sense and has stronger visual impact, because the crew rebuilt a high-speed runway for the ultimate excitement and realism, just for this drama, it cost 30 million US dollars.
