[SOLVED] Pluto Orbit Confusion

[dahemac]

I have tried and searched a lot of stuff about 1.6, but I can't find specific info on when 1.6 is in fact going to be released or if it is available anywhere. Some people seem to be getting versions from somewhere. Anyone got a link?

[ElChristou]

I have tried and searched a lot of stuff about 1.6, but I can't find...

Yes... a lot... Perhaps you should stop thinking people are just idiots. Even without using the search engine all the info needed in the 3rd (!) post of one of the forum...
(and no I won't give you a direct link )

[dahemac]

Thankyou. Your kind, patient, and above all, polite help has been of inestimable value to me in my search for a solution to this problem. Being completely new to these forums, I find that the advise and direction you have so willingly bestowed has really helped me not only to find the information I was looking for quickly, but also to feel a part of the Celestia community.

Thanks again.

Great! Happy to read that! You're welcome!
Just a thing to help you even more, next time try to study (even a little bit) the forum where you step in before posting, that's really not so hard. For example here, you cannot say you have search a lot when definitively it's not true. Most people here are civilized and don't like to be threaten as idiots by a first time poster. But I guess you have now a good picture of how this forum works!

FWIW,

I also can only see Pluyto's and Charon's orbits around the Barycenter, but NOT the heliocentric orbit.

Perhaps we should not assume that this bug is fixed for ALL users. Clearly it is fixed for some users and not for others, so perhaps this has something to do with the graphics chipset.
Perhaps those who have responded already to this thread would report their OS and Celestia version and graphics chipset so that we can establish a pattern, and get to the bottom of this.

Mine:
OS: Win32 (XP Home)
Celestia version: svn4679
Chipset: ATI shared memory graphics on a laptop.

BTW. Abramson's download location for Windows executables seems to be down at present:

dahemac,
I believe MAC OS executables can be found here: viewtopic.php?f=4&t=13449&st=0&sk=t&sd=a

Just so you know about it...

When I display Pluto and its moons, I can see absolutely NO orbit
displayed for Pluto itself. I have checked all the planet, moon,
dwarf planet and minor moon orbit boxes, but still see only the
orbits for Pluto's moons.

Using a late release of 1.6, although not the very latest.
Just FYI...

[ElChristou]

Chuft, Bob, are you saying you don't have the orbit of Pluto-Charon on a clean fresh build? (without messing with previous old data files, etc...)
(also, reminder, it's not anymore a planet but a dwarf planet...)

The bug *is* fixed... If you can't see heliocentric orbit of Pluto (actually the Pluto-Charon barycenter), this is mostly likely caused by one of two things, both of which ElChristou hinted at:
- You don't have dwarf planet orbits enabled
- Or, you have a Pluto add-on installed that hasn't been adapted for Celestia 1.6.0

The definition of Pluto-Charon in 1.6.0 looks like this:

Code: Select all

ReferencePoint "Pluto-Charon" "Sol"
{
    CustomOrbit "pluto"

    # Make the orbit and label visible
    Visible true
    Clickable true
}


Ordinarily the orbit of a reference point is not shown; this behavior is overridden by the line "Visible true". Try adding this to whatever Pluto add-on you have installed and it will almost certainly fix the problem.

I just updated the Wikibook documentation for Visible:

Thanks for the explanation Chris,

I must have an older version of solarsystem.ssc. Applied this definition and all is good now.

As an aside, I've wanted to make lagrange-points clickable for a long time, but I was unaware of this functionality. The next release will have clickable lagrange-points.

Thanks very much Chris...
That fixed my problem on this machine.
