  Pros'ba pomoch' v postroenii sfery, v centre kotoroi byl by nablyudatel', pri  
  uslovii,  
  chto sfera vrashaetsya vokrug osi, prohodyashei cherez ee centr.

  Problema v tom, chto neobhodimo vrashat' sferu otnositel'no osi, prohodyashei cherez  
  ee polyusa, no pri etom nablyudatel' dolzhen nahodit'sya v ee centre. Nuzhny  
  sootvetstvuyushie formuly ili primernyi algoritm postroeniya.  
   
  Ya uzhe sdelal model' vrashayusheisya sfery, no problema v tom, chto ya smotryu na nee s  
  ploskosti ee ekvatora, neobhodimo peremestit' tochku nablyudeniya v centr sfery.
