Alot of questions about collisions

/* This is for the game Rocket League*/

Hello, so I am trying to predict collisions inside of a UWorld. Right now I can predict the ball’s flight path by using an equation I made by getting 3 sets of x,y,z coordinates. This only works until the ball interacts with an object inside the world although. My problem is now, getting the coordinates of all the world materials that can cause collisions and check the ball position against those? I am kinda foggy on this part, and if anyone has some suggestions on alternate or better ways of doing this, let me know.

If anyone has the slightest idea on how to help me, feel free to comment. I’m willing to put in the work, I just need to help getting started.
