This is no-texture-on-a-mesh ! Fully volumetric all-sprites nebula.

EDIT : Another nebula prototype...

A family of five irregular nebulae :

These 3D models are great with stars inside, and placed in the galactic arms.

Here's a movie of one of them :

This picture isn't from Celestia. This topic is about pictures taken within Celestia, so you're OFF-topic. :roll:

what motivates you to say that ?

It is evident. :roll: Don't take people for idiots ! This is enough for a ban.

Or else, prove it by showing the corners info on your picture, with maybe other Celestia elements (stars, galaxies...) !

The model have been designed to match Celestia's galaxies rendering.

So I got curious how NGC 404 would look like in celestia.Sci in visible light. Here is the result along with a Hubble photo of NGC 404 (note I am using the SDSS color profile, while the Hubble profile is rather different):

Very different from the images above no ?

The picture that you're showing us clearly state that it's in the UV wavelenght band. In the visible (left part of the picture), we see nothing ! (the bright orange spot on the left is just a star, not the galaxy itself). So there is no contradiction with my model.

Secondly, my NGC 404 nebula model is only the central core, not the entire galaxy, which is still represented as a lenticular (S0) in Celestia.

And thirdly, your picture isn't showing a close-up of the central core.

NGC 404 is a very small galaxy, and we can't see its central core with our current technology. So we are still free to represent it in any way we like.

While the GALEX photo also shows NGC 404 in visible light (on the left) one should note that the orange color is NOT a real color, since a monocromatic DSS image was displayed. These are all orange colored ;-) . In contrast, the Hubble image I have shown for comparison represents a true color display (given the Hubble filters...)

That's very nice. You should put this picture in the irregular nebula topic at CM, to illustrate the "granulity" I was talking about.

That was actually the reason why I shot the image 2 days ago ;-) . Let's see when I get around starting the discussion at CM...

So this is not the good topic to deliver all your photos ?

After reading this kind of stupid comments, I'm now asking myself why should I continue to publish anything on this lame forum. :roll:
Why should I give any addons to disrespectful idiots like you ? So you don't like 3D nebulae ? Okay no problem, just forget about them.

I have enough of this moronic board. I'm leaving.

You had to choose this one: "Re: Custom Science-Fiction Pictures from Celestia" at :
http://www.celestiaproject.net/forum/viewtopic ... 1e9467536e

From Wiki (sci-fi search):
The settings for science fiction are often contrary to consensus reality, but most science fiction relies on a considerable degree of suspension of disbelief, which is facilitated in the reader's mind by potential scientific explanations or solutions to various fictional elements

There is no "suspension of disbelief" in believing that within NGC404 there can be several nebulae generated through the usual scientific ways with which they are generated, having proofs that nebulae exists within other galaxies now. On the other hand, there is no proof that faster-than-light ST/SW vessels exists now; thus there is the "suspension of disbelief" for what concern their existence "long time ago, in a far far away galaxy". Cham's works on sprites is a straightforward approach to get 3D nebuale as closest as possible to their real shape and Shatters.net is not Facebook, Twitter or similar devices for children mass-brain deseases.

Sorry, I do not agree. If the potential matter for the possibly existence of nebulae within NGC-404 were independent from its form, it should be constituted by gas/dust components like our nebulae; being its form, by the way, just the part that you considers fictional even though you must admit that sugar and coca matches their form but not their matter. Could you tell me what matter and form matches an unexistent sci-fi object aside the book's paper or the movie's film?
