Custom movements on FBX model

I have an FBX model and I can play an animation of the model. It works pretty smoothly, but I have to do something different.
I want to synchronize the model with a video stream from a camera. It is possible to build a skeleton form the video stream. The skeleton is quite similar to the skeleton of the FBX model. I want to sync those two skeletons.
I a nutshell the FBX model should mirror all movements of person from a video stream.

Is it possible? If yes, how?

What you are looking for is a technique called “Skeleton Tracking”. AFAIK, there is no code that you can use out-of-the-box for your three.js app. At least I’ve never seen a WebGL showcase in the last years.

However, you now know what technique you have to study in order to implement your feature :wink:.
