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!

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 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.

I turned the original 2D-image to 3D by using a surface modeling software (TrueSpace).
Image is first divided to layers by its content, each layer is then projected to a 3D-surface.
To have good and realistic forms, I did use an other software, Bmp2CNC, it converts the shades in the image to a 3D-form. I have semi automated the whole process, it'll takes about 20 min. to make a 3D model like in this example is used.
A screen shot from the TrueSpace modeling software.
This kind of model gives much more freedoms to animate, than is used in this example.
A series of 24 images, with about one degree increments, are needed for the lenticular 3D print.

An experimental animation of IC 1340
In this experimental animation the nebula, IC 1340, can be seen with and without stars.
Sometimes it's easier to see complex shapes of nebula without stars, specially if it locates in a very dense star field. Human brains has an ability to create some quasi-logical shapes out of the random cloud of dots, like stars, and it can interferes the underlying shapes to be seen clearly.
Original image and imaging data can be seen in this blog post:
