I have avoided using the mask, that I used in my contest entry, in this image to save a little time. Actually I don't know how I could have masked it from two viewpoints unless I rendered two seperate images. Also I left hair turned off and only rendered 1 pass. 5 passes produced a black image for some reason.

neat - I prefer the grey image rendition more - nice image

One thing, that I didn't realize is that there is no standard as to which eye should have the red filter (in your case the left) - no wonder sometimes 3d images were hard for me to look at. DUH.
Paul Forwood
Thanks, Nancy! I prefer the grey version too.

And, yes, I guess I should have specified that the red is for the left eye and blue for the right but the glasses that come with A:M are builit that way anyway.

Wonderful image paul!

Yeah, the gray looks great!

I think "color" anaglyphs are nearly hopeless unless it's a picture of something gray to begin with.

Red on the left is the convention.

I once read an article by someone who claimed that most people who can't see anaglyphs could see them if the were made the opposite way, however. Some kind of right-left brain thing, but I've never seen anyone do a study on it.

The only way I found out that there was a different way was when someone awhile back (I believe it was you robcat) posted camera taken stereoscopic photos from a Tim Burton movie? and the red was on the right -

Meanwhile I found out my hash glasses are reversible cardboard.

They worked just as well as standing on my head.

i'd appreciate a crosseye freeview render, since i look silly wearing those red/blue glasses. ' ' )

Okay. Just for you, Jon. wink.gif

Unfortunately A:M doesn't cross the images for us. Here it is with the L and R switched for correct crosseye viewing. smile.gif

Looks great!

yay! thanks paul & rob! ' ' )

Lovely image! I too prefer cross eyed version. It can retain colors and you don't need those pesky glasses... However, people tend to look even sillier lurking cross-eyed into their monitors wink.gif
Paul Forwood
Thanks,everyone!

Robert, I am very grateful for your corrections, as I am for anyone who corrects my errors, but I think the first image was the right way around. A:M labels the images as L and R. If you look at the flower behind the fairie's left wing you can see that the perspective would be correct in the arrangement that I posted, unless I am very mistaken.

Thanks again though. I always respect your criticisms. smile.gif

Looking at them in 3D the top one is inside out.

But we can examine this without looking in 3D. Basically, object pairs that make the eyes converge more appear close and pairs that make the eyes converge less appear far.

Our left eye is looking over at the image on the right and our right eye at the one on the left. Lets compare overlapping wing and flower in the two images.

Compared to the image on the right, in the image on the left the the flower is somewhat farther left than the wing, meaning our right eye has to turn aim left, or converge, more than it does for the wing. And that makes it appear in front of the wing.

Possibly you are one of those rare people who can view non cross-eye pairs, for whom the top version would appear correct. I can't do that unless the images are very tiny.

That is "divergent viewing" and it can indeed be done... I can do them both, but cross- eyed is much easier and requires less time for adaptation...

i can view (bring to focus) both images, but the second one looks correct, with the fern leaves on the lower left and upper right popping out of the screen.

the first image is what the right eye will be looking at when crosseye (paralax?) viewing.

Ahh! Okee dokee, Robcat. I get it now.

I prefer to view with uncrossed eyes so I didn't even attempt to view this image correctly. I see the logic though so thanks for that! smile.gif
