This is the project that motivated me to learn how to use Three.js in the first place. I had the idea for the project first and needed a way to display things on-screen in an interesting way, so I learned Three.js to make it happen.
It’s now a few months later and I’m working on making an improvement, which is to place markers on objects to point out their locations to users even if they are too small and/or far away from the camera to see. This requires projecting the positions of objects from 3D world space into 2D screen space. I’ve run into some difficulties with this, which is where this post came from. Any advice on that would be appreciated.
