Left or Right Brained? Check this image. - Page 14

Even from top it can rotate clock and anticlockwise. The problem because seh is flatshaded you cannot recognize which is her left and her right leg. If you project an object and its mirror image to a plane they are indestinguishable.
When she is standing on her left leg she rotates clockwise, when standing on the right leg, CCW.
But IMO that has nothing to do with brainsides.

Everytime I open this thread I see it counter clock wise and after opening the spoiler I see it clockwise im confused.

Ok.. am I retarded?.. I just had a fight with the guy who linked with me because I was trying to explain.. "if you look at the image from the TOP of her HEAD the image is rotating COUNTCLOCKWISE"

"if you look at the image from the BOTTOM of her FOOT the image is rotating CLOCKWISE"

In order to use the word spin you must have an axis.. for me the axis is from the bottom of her foot(the one that is moving LESS) to the top of her head (this is the most reliable axis you can take... by that I mean this is the axis where her spinning is the most concentrated)
There is no wrong answer this way.. anyone who said its obvious which way she is spinning is fucking stupid.

Consider a silhouette made by parallel beams of light on a flat screen, of the dancer turning clockwise (as imagined from above), turning to her right. The parts of her body on the right side of the image will be moving toward you, and the parts of her body on the left side will be moving away.

Now consider the silhouette of the same dancer performing the same action, but with the light source and flat screen rotated 180 degrees, a perfect half-turn, around the dancer. She is still turning to her right, still clockwise as imagined from above. The parts of her body on the right side of the image will still be moving toward you, and the parts on the left will still be moving away.

This silhouette will be flipped left-to-right compared to the first one, but otherwise identical.

Now imagine you are watching the dancer through a mirror, not a silhouette but directly seeing her. She would look the same as a dancer turning to her left. The parts of her body on the right side of the image would be moving away from you, while those on the left would be moving toward you.

Now imagine watching the original silhouette through a mirror. The direction of her rotation should be reversed by the mirror, but the mirrored silhouette is identical to the silhouette from the opposite side. Although one image is derived from the dancer facing you then turning to her left, while the other image is derived from her facing away then turning to her right, they are identical.

Since, a parallel-light silhouette does not allow you to distinguish between a mirrored image or an opposite-side silhouette, you can't determine which side you're watching from unless there is a known asymmetry. For instance, if her left hand was a lobster claw and you knew it, when her breasts faced right, you could judge that the lobster claw was behind her and determine the direction of her spin from that. If the lobster claw appears next to the right (following the breasts), she is turning to her right, if it appears next on the left, she is turning to her left (preceding the breasts).

For a perspective view rather than a parallel-light silhouette, the parts of her body will change size as they move closer or farther. If her hand grows, you know it is moving toward you. If her foot shrinks, it is moving away. This would also be a way to judge the direction she is turning.

I believe that there is a perspective cue in this image. Notice that the image is being moved up and down so that her lifted leg appears to be holding at the same height. I think her lifted leg appears longer when it is closer, so the toes are lower, and the body (most noticably the supporting foot) is raised to hide this and confuse the eye.

So when the feet are closest together vertically, the lifted leg appears longer, is closest to the camera, and is therefore in front. While when they are farthest apart vertically, the lifted leg appears shorter, is farthest from the camera, and is therefore in back.

By this reasoning, she is turning to her right, or clockwise from above.

I think this is only a perspective view rotation which has been altered to seem more like a parallel-light silhouette, and if you see her turning to her left, you're missing visual cues that conflict with this interpretation. But I'm not terribly certain.

Any counterarguments?

It has a lot to do with 'insufficient data' to the brain. See the pics I posted above. You can't see her elbow or whatever and your brain goes "Oh it must be behind" or "Oh it must be in front" and makes everything else match up the same way.
