<div>As it looks you liked the English title, here is the French translation:</div>
<div> </div>
<div><strong>Choisir entre rectilinéaire/cylindique/équirectangulaire : c'est facile!</strong></div>
<div><strong></strong> </div>
<div>Hmm, I should add that this tutorial only deals with the </div>
<div><font color="#ff0000">easy cases!</font></div>
<div> - cylindrical <em>vertical</em> panoramas, which must be assembled using</div>
<div> 90° roll values (or rotated after creation) are not covered.</div>
<div> - large <em>vertical</em> FOV panoramas (to be more precise: panoramas</div>
<div> where the angle between the top or bottom and the horizon line</div>
<div> is higher than 60°) are not covered.</div>
<div> </div>
<div>Some day, perhaps...</div>

<div>Most tutorials I wrote for my website derive from this post </div>
<div>(on Max Lyons forum) by John Houghton:</div>
<div><a href="http://www.tawbaware.com/forum2/viewtopic.php?t=450&highlight=sphere">http://www.tawbaware.com/forum2/viewtopic.php?t=450&highlight=sphere</a></div>
<div>where he explains that PToptimizer "places" the sources images </div>
<div>on a sphere ( = decides of their best possible yaw, pitch, roll </div>
<div>and FOV values) while PTstitcher used those computed</div>
<div>values to project this sources images sphere on a plane or cylinder...</div>
<div> </div>
<div>This completely changed my understanding of the way</div>
<div>Panorama Tools works!</div>
