Hi addon makers,
You surely know about the heliosphere, if not so just take a quick look at http://en.wikipedia.org/wiki/Heliosphere.
The Heliosphere is an amazing structure of the solar system. It is mainly produced by the Sun and with a little bit of imagination it looks like a cell in biological terms.
Something so fundamental should be in Celestia !
May the Force be with you.

Welcome!
As I was making my Voyager and Pioneer models, I've done a test model for the heliosphere, but such model cannot be used because it cause lots of problem of selection. From outside you cannot select anymore the sun and planets, from inside things become also not so easy to select...
For this kind of stuff, we do need an unclickable class...

With the exception of stars, Celestia is designed to render things as they would appear to the naked eye. The heliosphere and helipause are completely invisible. If you want to create it, that's fine, but I'm sure it would remain an add-on, and never be used in the default version of Celestia.
Current Setup:
Windows 7 64 bit. Celestia 1.6.0.
AMD Athlon Processor, 1.6 Ghz, 3 Gb RAM
ATI Radeon HD 3200 Graphics

Hungry, I think boubaz knows this; see the first line of his post... (and it's also why I took the time of answering! )

Re: Request : Heliosphere
For now this could easily be a nebula, but I agree a simple "unclickable" class would be awesome. This is also another reason for raising the SSC view limit.

Re: Request : Heliosphere
I agree, however IMO a more elegant solution (rather than simply raising the limit to a higher, yet still arbitrary value) is to decide whether to display the object based on it's apparent size onscreen (regardless of how distant it is from the observer).InconspicuousBarrel wrote:This is also another reason for raising the SSC view limit.
eg. As an object's displayed size becomes smaller and smaller (either by moving the observer further from it, or just zooming out using the . key), eventually the object may subtend an angle significantly smaller than a single pixel, at which point there's no point displaying it anymore.
Likewise, using the , (comma) key to magnify a very distant object, would only display the object when you have narrowed the FOV enough that the apparent size of the object is greater than the approx. size of a pixel.
So with this approach there is no need for an arbitrary cutoff limit, as objects will only be displayed when they need to be based on their apparent size on screen (regardless of distance).
I think I've made this suggestion already to Chris some years ago, but I don't know if he has any current or future plans to address this issue.

Re: Request : Heliosphere
I like that idea! I wonder if it would be possible to include orbits as well as just objects.

Re: Request : Heliosphere
BTW. I believe that what I've described above is somewhat similar to how the code already works for objects within the 1 LY limit, it's just that over the 1 LY limit they just don't get displayed.
In practice, any planet in any solar system (ie. in an SSC file) would be so small as to be invisible at this range, which is probably why Chris originally decided on that limit, however it ruins it a bit for extended objects like the helosheath, the heliopause, or Rungworlds and Ringworlds.
