   modifying vertices on quadratics? is it possible?
  hi. i was just wondering if modifying individual vertices on quadratics(i.e. spheres) is possible, in order to establish morphing effects. thanks! 
  No I don''t think you can. Better create your own shpere.   "C lets you shoot yourself in the foot rather easily. C++ allows you to reuse the bullet!"  ;  Perhaps feedback mode would help. There was some hassle with the z-coordinate though. ;  hmmm interesting stuff... how does feedback mode work? ;  I don''t really know. I''ve only read about it.  Basically it fills a buffer with the coordinates of rendered vertices instead of rendering to the screen although you have to apply some (simple) operation to the z-coordinates in the buffer to get the real ones. I''m sure google will help you find some tutorials. ;  The feedback is much harder to use than to just calculate the objects yourself, or make them in a 3d model program amnd make your own file reader for the choosen programs file format.;  Feedback is slow.
