Hi there thank you! I saw that diagram the other day too on a different thread my question is what happens if you turn them around so the small points are touching? Does it totally change the triangles? It probably doesn't matter but I've been wanting to do the ice cream cone thing either which way.

I don't know which "small points" you mean but I should have withdrawn that and submitted a better thought out version.

The key thing is that extended the thin blue lines is not how Depth Of Field works but many people think this is so.
What's important is the the near and far rays meet at the edge of the Circle Of Confusion on the image plane (sensor).
