I'm playing a 3D game. I got a camera which can be set in first-person and third-person view. I already know how to grab entities around my main character and display them in a small 2D image, in a corner of my screen. Now i want a 3D radar. My objective is drawing a point on my screen for each of these entities. I'm playing in third-person view. There are a lot a things i can think of : camera direction, zoom (fov ?) Can you help me structuring this project ? What are requirements (i only have X/Y coordinates) ? Which maths can help me doing that ?

example
