A developer in Hong Kong built a free app that turns your webcam into a 3D mode. It's called SysMocap. Here is what it does. You open your laptop. You point the webcam at yourself. The app watches your face and your body. Then it copies every move you make onto a cartoon 3D character on screen, in real time. You smile. The character smiles. You wave your hand. The character waves. You turn your head. The character turns its head. That is it. That is the whole tool. You can pick any 3D character you want. The cute anime kind from VRoid Studio. The fully rigged ones from Mixamo. Just drag the file in and the character starts moving with you. What people use it for: → VTubers who want to stream on Twitch or YouTube as a cartoon avatar instead of showing their face. → Anyone who wants to record character animations without buying expensive mocap gear. → Hobbyists making short films and social clips at home. → Streamers who plug it straight into OBS for live broadcasts. The closest paid alternative, a Rokoko Smartsuit Pro II, costs $2,495 for the suit alone plus $20 to $50 a month for the software. SysMocap does the same job with the webcam you already own. It works on Windows, Mac with Intel, Mac with Apple Silicon, and Linux. No account. No login. No cloud. It runs entirely on your computer. The whole thing was built by Wang Xianfei, linked to the Hong Kong University of Science and Technology. One person. Three years. 26 releases shipped. 2,955 stars on GitHub. The license is MPL-2.0. Free for hobby use. Free for paid streams. Free for client work. Forever. This is what motion capture should have looked like from the start. (Link in the comments)
