How does ortho view translate to perspective view?
I want to use ortho view in the main menu screen on mobile, but then switch to perspective view when I am in the game so I can create 3d shapes. I am curious how to do so. I now have the settings so that both ortho camera and perspective camera are showing the objects the same size (see attachments). This was set through playing around with the settings, but I want to know if there is a specific calculation used so I can set it in the script.
Another question is if I am in perspective view, how can I determine that the object has reach the edge of the screen?
