Hello,

My apologies if this post is in the wrong forum. I am currently creating a model of a train which is my first openGL project.

I have a set of large wheels which I wish to be connected together with a bar - imagine an old steam train.

Below is a screenshot of what I have so far.

I want the blue bar to give the impression that is is connected to the 3 large wheels, however I am not the best at maths, and do not know how to perform the sin & cos calculations to make it translate in a circle! I need to be able to control the speed of the movement so that it matches the rotation of the wheels

Any advice would be appreciated
