M81, 3D transformation
This is example image of three dimensional transformation.Original 2D image of M81 is now turned to freely rotatable object.
Pretty far from actual astro photography, umh...
Interesting tough.
M81, Odd Stereo Pair
Parallel vision
Cross Vision
As you can see, this stereo image looks litlebit odd, since you can not see this galaxy from this
angle anywhere from Earth! Explanation in previous post.
M81 experiment
This image pair is not a stereo one.On the Left image, M81 galaxy is as we see it from our home planet.
On the Right image, M81 is seen from directly above!
I was doing stereo pair from Glaxy M81 and I needed to correct the galaxy to "flat"
(perspective correction)
The shape of the galaxy is more visible by that way, I think. Anyhow funny looking
transform.
I can now make a grayscale hight map out of this corrected image.
When corrected bitmap is projected back to the 3D surface, I have a model of galaxy.
Now it's possible to freely rotate the object and selext any vantage point to observe.
Veil Nebula, NGC 6995, stereo
Parallel Vision version
Cross Vision version
The fine filaments really stands out in three dimensional image.
