title: Augmented Reality with large and complex markers
body: <p>does anyone have any experience with using large and complex images as markers (e.g. magazine layout, photo, text-layout) for a.r.?</p>
  
  <p>i am not sure which way to go:</p>
  
  <p>flash, papervision and flar would be nice for distribution but i suspect them to be too bad in terms of performance for a more complex marker than the usual 9x9 or 12x12 blocks. i had difficulties achieving both a good 3d performance and a smooth and solid detection.</p>
  
  <p>i can also do java or objective-c with opengl/opencv and this is definitely also an option for this project.</p>
  
  <p>i just would like to know before if anyone has had experiences in this field and could give me a few hints or warnings. i know it has been done already so there is a way to do it smoothly.</p>
  
  <p>thanks,
  anton</p>
