How I would create a curve between points?

I’m creating a game that allows you to create paths(roads) but I don’t have any structured idea about how to get the position and angle of these curves between two points, let me show an example
curve
How I would find the radius and the position of the curve or being honest, how do I would start? I need to say that I’m not very advanced at math

This can be accomplished with Bezier Curves (documentation linked). What you’re looking at is a quadratic bezier curve, which uses three points in order to generate a curve. As you have in your photo, you need two end points and a third point to guide the curve. It may seem like too much math, but it’s more simple than it seems. Just go through the documentation and apply it to your situation.

How I would visualize them as 3D parts, I read the last part and I got the method to get the angle and position but I didn’t find any solid explanation about how to visualize the objects in 3D

every time you lerp on the curve, contruct a part on the location.

Is there a plugin that will do that for me so I don’t have to run my code everytime I want to see what the curve looks like
