He Turned a Physics Textbook into a 3D Interactive Demo—and the Comments Are All Asking: How Did He Do It?
Energy concepts from a static textbook become a rotatable, clickable 3D scene. One commenter said: “If I’d had this when I was in school, what would we even need teachers for?”
A static physics textbook page has been turned into a 3D interactive learning scene. In the video, energy concepts that were originally printed on paper become three-dimensional models: the sun, containers, a bicycle, and a balloon. Each element can be observed, and the energy values on the containers change as you interact with them.
This is a demo posted by Kai (@hqmank). His caption: “Absolutely stunning.” A static physics textbook becomes an immersive, interactive 3D learning experience, “where you can truly explore these concepts instead of just reading about them.”
The post quickly sparked discussion. One commenter said: “If I’d had this when I was in school, what would we even need teachers for... Though now, when my son gets stuck on a problem, I just have the Grok bot make him a dynamic video.” Another said: “This is what textbooks should have been like from the start. Reading physics and poking at it in 3D are completely different things.”
People also shared production insights. Steve said he used the same tech stack (Opus + Three.js) to build a machine explainer and found one key point: free rotation only makes the experience feel fun; the real “Oh, now I get it” moment comes when the camera settles on a specific part and the rest fades to semi-transparent. “Without that, users are just spinning the model and missing the point.”
John Kovacs raised concerns about accuracy: “If a static diagram is wrong, you can spot it immediately. But if a Three.js simulation is slightly off physically, it can still look perfectly fine and quietly teach users the wrong intuition. So every interaction still has to be checked by a human against the real equations.”
The comments also raised some practical questions: How long does it take to finish a chapter like this? Someone suggested making it into a Claude skill. Another commenter mentioned that @techartist_ is one of the best people at using Three.js, with an extremely broad range of work.
The exciting thing about this kind of attempt is that it turns “reading” into “hands-on.” Textbooks are no longer static paper; they become models that can be taken apart, rotated, and touched. Whether it can scale will depend on production cost and simulation accuracy. Which subject would you like to see transformed first?
