WebMar 8, 2016 · the center of the circle is inside the ellipse, or; the center is outside but the distance between the point and the ellipse outline is smaller than the radius. Testing insideness is immediate (plug the coordinates of the center in the implicit equation of the ellipse and check the sign). Computing the distance is another matter. WebAug 10, 2024 · The center of the ellipse that’s the projection of the circle will in general not be the projection of the circle’s center. It will “drift” away from this point. This is because for a finite camera, i.e., one positioned a finite distance from the image, the projection is asymmetric: rays from the camera to the edge of the circle that ...
