Yes, Agreed. As drawing - With a viewpoint on the face of a spherical bubble, circles drawn on it, when viewed with a sight line through the centre of the bubble, will all have true circular images. Full circles though, are all outside our cone of vision but it seems that if you are standing the...
Thank you all.
I believe that the "tilt angle" is solely related to the location of the observer ie: x degrees left or right and y degrees above or below the centre of the disc. It has nothing to do with the distance from it or it's radius. And that angle is unique to that location.
What I will...
Thanks for all your replies.
Yes, maybe but it does tilt.
And yes, the major axis would be vertical if the camera was level with the hub - (and horizontal if directly in front).
I imagine viewing a flat circular lollipop being rotated by its stick viewed from, say below its centre. During the...
The undoubted tilt of the axes of the elliptical image relative to the horizontal.
Yes, I see we are projecting the image of what we see on to a 2D plane orthogonal to the line of sight.
So the "tilt angle" should change if we pan the "camera" up, down or side to side.(that is, change the angle...
Good Morning everybody. I hope that this thread is of interest.
I am a retired architect with an interest in Mathematics.
My picture shows a view of The London Eye.
We know that it views as an ellipse but the major axis (drawn), clearly is not at right angles to the axis of the wheel and if you...
