Hi there, thanks for reading, what I want to make is a 3D image gallery, where if you put the mouse pointer to the right side of it, it will start to roll to the left so you can select an image to view, the problem is that I don't know where to start, I don't have any level loaded because it's a 2d program and I don't want to load a level because everytime I load one level, the fps decreases, what should I do?

here's an animation of what I want to do



I hope you can help me.
