Rowan Cheung 用 Codex 把健身视频做成可交互 3D 工具

Link in bio to download the ChatGPT desktop app! I used Codex to turn my workout footage into an interactive 3D tool, and it came together faster than I expected. The tool lets me replay my movement, rotate the model, explore the muscles involved, and ask questions about the clip. ChatGPT’s Intelligent UI helped me explore the idea before I built and tested it with Codex. Publishing it through Sites was surprisingly straightforward too. After spending so much time covering what other people build, this was fun being able to take my own idea and turn it into something usable in such a short period of time! @ChatGPT #ChatGPT_Partner

AI 导读

Rowan Cheung 用 Codex 把自己的一段健身视频做成了可交互 3D 工具，能回放动作、旋转模型、查看涉及的肌肉并针对片段提问。他先在 ChatGPT 的 Intelligent UI 里探索动作涉及的肌肉，再把参考带进 Codex 搭建，并解决了模型与视频暂停、回拖时的同步问题。最后他通过 Sites 直接从 Codex 发布，拿到一个可分享的链接，无需单独配置托管、服务器或域名。

So, i turned a video of my workout into a 3d model i can take apart. Basically, i use codex to build a tool where i can upload a clip, replay my movement on an animated body, and pause at any point to see what's happening.

If you look closely, i can rotate the model, reveal the muscles, and ask questions about specific moments in the recording.

I often ask it things like how's my form, what could i improve on, and how can i get more out of this exercise. I started in ChatGPT and asked it to show me which muscles were involved in the exercise.

With intelligent ui, i could click through the diagram and ask questions about what i was looking at, and that helped me figure out what i wanted people to see when they clicked on a specific part of the body.

So then i brought that reference into codex to start building. Codex connected the video with an animated model, and then added a way to ask questions about what's happening in the clip.

And along the way, i kept the references, design decisions, and feedback in a shared page. If my shoulder feels sore, i can select that region and open up a panel beside it with illustrated stretches and strengthening exercises.

Now, the tricky part was actually getting the model to stay in sync with the video. When i pause or drag the video backward, the model needed to match.

But it was really easy where. Working through that with codec, so i just tested the playback and compared the models movement with the original footage.

And after that, i just tested the complete experience on my phone. And once it was ready, i used sites to publish it straight from codec, without setting up separate hosting, configuring a server, or even buying a domain.

It just gave me a link i could share. Click the link in my bio to download the ChatGPT desktop app, and try out yourself.
