Surface of revolution [i]b[/i]([i]u,v[/i]) is given by half meridian [b][i]a[/i][/b] and vertical axis of revolution ([color=#0000ff]blue[/color]). Sliders for parameters [i]u[/i] and [i]v[/i] determine the position of point [i]A[/i] on surface.

Construct the missing projection A2 of point A on surface in multiview projection.
