Veil 3D-movie
This is really interesting! (least to me)
I divided the original 2D-Veil image to the layers by the content.
(parts of nebula, stars by size and the background)
Each layer was then projected to the 3D-surface.
The main principle is about the same as in Stereo Pair images.
In this tecnique the data is really in 3D-format though.
I think this video tels a lot about nature of this object as a 3D bubble, leftovers from
massive explosion, Supernova.
NOTE. This is not a accurate model, it's more like an educated guess about appearance.
The original 2D-image, with imaging details, can be found here:

3d-stero pair image is here:

and
Stero pair animation! of exploding star is here:

There is couple of hick-ups in the video, since I'm very new with any animation techniques, yet.
Video compression kils the movie here. Original
HD-quality movie has stunning details and about zilion and half more stars.
Flame Nebula Animation and the bad weather
The wearher up here leads me to do experiments, since imaging is not possible.
I have done some Stero Pair images ealier, now I have made an 3D animation based on
same general idea.
Original image,
is splitted to layers and grayscale vesion of the starless nebula image is turned to Hight map.
The Hight map is the turned to 3D-surface, stars are projected to other surfaces to
create volume information.
This is a very quik test for this technique and far better results can be archived with it.
This is an animated GIF, size is about 3Mb.

Cassiopeia A as a Stereo Pair
Weather up here at 65N has been cloudy about a month now.
I played with my image of Supernova remnant, Cassiopeia A.
(Original post, with imaging details, can be found here:
In original image, I was seeing an outer shell of hydrogen gas (Green).
In this stereo image I have tryed to bring that structure out.
Two versions, first for the Parallel Vision method and Second for
the Cross Vision method.
