Oloid animated

An oloid is a three-dimensional curved geometric object. It is a convex hull of a skeleton frame, made by placing two connected congruent circles on perpendicular planes with the center of each circle on an edge. from the second round. The distance between the centers of the circle is equal to the radius of the circles. One-third of the circumference of each circle is inside the convex hull, so the same shape can be formed as the convex hull of the other two circular arcs.
