+Omar had the idea that we just look at where the object is relative to the camera and exclude the side that's likely to be distorted. Here, the camera is above and to the right of the viewport, so we cast rays from the camera to the convex hull of the contour of the object and take that green arc between the two tangent points:

 {{newsletters:img_6973.mp4?350px}}
+That should get us the 'side' of the contour that is touching the viewport plane (should be unaffected by moving the cup further away or to different sides of the camera, unlike just finding centroid of contour), and then we fit a circle of the right diameter to it? More on this next month.
