Is it possible to display 2 videos in one window?

Question

JavaScript

Hello. The task of interacting with the user's web-camery with a 3D model has become a priority.
The interaction consists in determining the position of the user's head relative to the window and launching a certain animation of the model.
The situation is such that if I connect the model after the camera, then only the model is visible.
If I connect the camera after the model, then only the picture taken from the camera is visible.
Is it possible to somehow make both the camera and the 3D model work on the same page at the same time?
How to do it, what to read?
PS Maybe it will be clearer prntscr.com/jb67tf

Answer 1

As I understand it, you want to overlay a 3D model on the image from the camera?
Have a look at MultiStreamsMixer or video-stream-merger or this SO answer , it might help.
