axis, code

Paul, will you consider to provide the code that draws the figure and/or to correct it by yourself. It seems to me that the vertical line (that represents the axis of the conic surface) should be visible until the centers of the ellipses created by the intersections with the planes, I mean the case of red ellipse and the green ellipse; in the similar way as you did it for the uper and lower white circles. (In addition, you may consider to draw a square evolving the ellipse in each case, in order to represent better the planes.) Dmitrii Kouznetsov 18:07, 2 May 2010 (UTC)

Dmitrii, I made a new effort with Autocad (no code), but I'm not quite happy with it. Can you do better?--Paul Wormer 10:55, 3 May 2010 (UTC)
