The following pictures are the synthesized stereographs for Eagle Nebula (originally taken by HST). Please view them with parallel eyes or crossed eyes.
For other planetary stereographs, visit; http://139.134.5.123/tiddler2/stereographe...bula/nebula.htm |

Hi Harry, I like very much your 3D works. I would like to visit the page that explains how to do that but it doesn't work..
![]() How can I view this page? http://139.134.5.123/tiddler2/stereographer/stereograph.htm Bye, Ale. |

Ciao, Malgar
![]() About link malfunction, using windows, I'm able to see the page in the link, even if I'm required to insert my email adress in order to avoid spam (and t hen appear a "Comment/Enquiry Form" to be filled). However, also in the link no clear explaination is done about method to extract/assign depth information... even if not said, visualization method should be "parallel eyes" but this limits images sizes! ![]() I do not easily visualize parallel eyes stereograms and I prefere crossed-eys... using this technique, nebulae/galaxies are realistic because luminous (closest) stars appear in the foreground. So I suspect they are wrongly showed in background in the original "parallel eyes" version... Harry, is possible to correct it? -------------------- I always think before posting! - Marco -

Surely I didn't mentioned whether "parallel eyes" or "crossed eyes" should be applied for in the website. Actually some of pictures in the attached gallery are for "parallel eyes" and some others are for "crossed eyes"! I should have noted which method is applied for each pictures... By the way I attached another synthesized stereographs (software: Stereographer, focus depth:=2, slide level:=3). Please view them with parallel eyes or crossed eyes you prefer. |

QUOTE (Harry @ Oct 24 2005, 02:28 AM) ... By the way I attached another synthesized stereograph. Do you see it with parallel eyes or crossed eyes? (for me it is better or realistic to see it with parallel eyes.) I tried both methods... Also for this image, I prefere crossed eyes view for two reasons, both already mentioned: 1) Stars look closer than Horse nebula, as they should; 2) I'm not confortable with parallel eyes method, and I cannot perfectly focus in this way ![]() Generally speaking, parallel eyes give the sensation to see an infinitely distant object (which is a clear benefit for these astronomical subjects) but have a great handicap related to the small images dimensions needed to see it (distance between images centers shouldn't exceed inter-ocular spacing, in fact I had to rescale them on the screen of my monitor..). I suggest you to split your beatiful gallery in two sections, based on the method to be used. Anyway, we all are asking the same thing to you: how did you extracted so "realistic" and detailed depth informations from original images??? The result is so amazing that I'm seriously thinking some kind of magic! ![]() -------------------- I always think before posting! - Marco -

The result is so amazing that I'm seriously thinking some kind of magic! ![]() I found some people prefer crossed eyes view and some other people don't. So I think I should prepare two types of stereograph, then he or she can choose parallel eyes view or crossed eyes view which he or she prefer. I modified previous my posts by adding stereographs for different viewing method. The method I employed is for detecting the deviation from focal point on each spot of the original picture (for detail of that method, please visit: Focus Corrector.) However it can not distinguish whether that deviation is in front of or behind the focal point. Therefore the viewing method (i.e. parallel eyes or crossed eyes) applied for the stereograph depends on whether the focal point is in the foreground or background of original picture. That's why the stereographs for parallel eyes and crossed eyes are mixed promiscuously in my gallery. Following your suggestion, I'll modify my gallery by adding stereographs for different viewing method. |
