title: Image transformation from 2D coordinates to Cylindrical Coordinates
body: <p>I would like to convert a Jpeg image (its coordinates (x,y)) into a Cylindrical coordinates.. </p>
  
  <p>Is there a function in opencv that can do this directly? or what functions in opencv can I use to create my own?? </p>
  
  <p>I am having confusion between 2d coordinates, 3d coordinates and cylindrical coordinates.. can someone briefly discuss this? </p>
  
  <p>Is there a mathematical algorithms available to convert 2d to 3d? 2d to cylindrical coordinates? 3d to cylindrical coordinates? </p>
  
  <p>I read the previous post regarding this topic but does not understand it.. </p>
  
  <p>I have not take a course on image processing but I'm in a rush to read books.. 
  I learn by experience and by studying other programmers code.. so source code will be much appreciated.. </p>
  
  <p>thanks to everyone and sorry for my elementary post,, </p>
