Figured I would add a stereo pair of the original posting. A larger image can be seen here;

... thanks, this is out of my range of understanding. It looked fine with my stereo Pocket 3Dvu glasses 'or' cross-eyed. Here's one with the left and right swapped.

Thanks, at least I have something to go on now. I've never even heard of the term, gastropod, or what a Paleobiologist might do. Looks like it might be closely related to this;enricosavazzi wrote:The two pink/violet ones are fragments of the capitulum of balanid barnacles.

If it looks good both ways, that says your personal visual system is not very sensitive to depth inversion by itself. I get the feeling that's pretty common -- it seems like a lot of people have trouble distinguishing correct from inverted with scenes like this where nothing in the foreground hides anything in the background. Depth inversion is much more obvious with scenes where say one leg passes in front of another, or an antenna passes in front of a face. In that case if the depth gets inverted, then it looks like the thing in back hides the thing in front (!), and most people will recognize that at least to the level of "looks weird".Smokedaddy wrote:... thanks, this is out of my range of understanding.

Like this hair (or whatever it is) and the changing depth of the yellow arrow ...

In concept, yes. But this is not a very good example because the hair is thin and not very far in front of featureless background. The effect is most obvious when the foreground occluder is larger and is much farther in front of richly textured background, so that the stereo depth of each object is clearly established.Smokedaddy wrote:Like this hair (or whatever it is) ...
