I understand now that you said there is some distortion to the drawing, but I got the idea that the circles at the wide end of the cones would appear to be offset. That is incorrect?

The third diagram with the curved lines is what really happens but it is crudely drawn.

The "cone" bases would be the same size and the sides of the "cones" would be curved.

The far "cone" is taller than the near "cone". In your example and mine I tried for 2x taller. (2/3 far and 1/3 near)
