An experiental 3D-animation from my image of Veil Nebula SNR



I have tested a new method to publish my 3D-images as a form of Lenticular prints.
For this technique to work, I need series of images from different angles, in this case 24 images are needed.
Lenticular printing is actually an old technique but in past few years it has become much more sophisticated.
The results can be stunning visually, image plane disappears and object floats in and outside of the frame.

Since astronomical objects are too far away, no real parallax can be imaged. Doe to that, I have developed a method to turn my images to various 3D-formats. My work flow is based on scientific data from the object, distance and the source of ionization are usually known. The different types of the nebulae has typical structures, pillar like formations must point to the source of ionization, the radiation pressure forms kind of hollow area, inside of the nebula, around newly born stars, dark nebulae must be at front of the emission ones to show, etc... rest of the missing information is then replaced with an artistic vision.
The whole process is pretty much like sculpting!

Please, wait for few moments for animation to load, the size is ~7MB

NOTE. Only real data from the original 2D-image is used for the 3D-animation!

This animation shows the estimated shape of the Veil Nebula. It has to be more or less spherical due to nature of the supernova explosion.

Generally images about space objects shows them flat as a paintings in a canvas but in reality, they are volumes floating in three dimensional space. The purpose of my work is to show how I personally see those distant objects in my mind and they are fun to do!
The accuracy of the model depends how well I have known, figured out and guessed. Right or wrong, if my 3D experiments are giving something to think, they are working well.


The original 2D-image of the Veil Nebula

I shot this image at Autumn season 2011. The blog post with information and technical details can be seen here: http://astroanarchy.blogspot.fi/2012/03/veil-nebula-reprocessed-with-some-new.html

The apparent scale of the Veil Nebula

Many nebulae are very large in the sky. This image series shows the apparent size of the Veil Nebula compared to size of the Moon. (The full Moon has an angular size of ~30 arc minutes, that's equal to ~0,5 degrees.)

Note. The apparent size of the Moon is marked as a white circle for a scale.
