Have uncovered my particular FPS problems with FT1.1 thank you very
much. :wink:

Your installation includes a 2048 x 1024 texture of the Earth in the medres
folder. As I have mentioned before, my particular machine cannot
even normally display a 2k texture. For whatever reason here, it does
allow the Earth texture to be displayed and used, but at the cost of FPS.

Just thought I'd make your day here. <Hee, hee>

Seriously though, all I had to do was copy a 1k version of Don Edwards'
beautifu Earth into my medres folder, remove the 2k version which came
with the install, and now my FPS are HUMPIN.

:lol:

Thank you both for the help and advice you gave me while trying to
find out what my troubles were. Toti and Fridger, you guys are the
BEST.

Hope this advice helps someone else here.

Thanks.


Hey Bob,

I am really glad to read this! I certainly know about the endless frustration (from lots of personal experience!) , if things don't quite work as they are supposed to.

Well in this whole game, it is an almost endless race for getting hold of these "infamous" little nasty issues that can get us easily into a "boiling stage" ;-)

Cheers,
Fridger

I concur. The first personalization I made was commenting out the set marker.

Frank,

I wanted to include FT 1.1 in my CD for ONLY one reason. It is worth it! I am not going to sell any more CD's because of FT 1.1 Teachers will not know it is even present. They will buy Celestia Educational Activities because they want a stunning educational program to take their kids into space. Whether the CD includes 1.4.0pre6 or FT1.1 will make no difference in sales, or in my profits.

OK that sounds fair enough...Also as I said, I don't have a problem with this. I just thought the CD publisher was sitting in your neck!

What it will do is give everyone who experiences Celestia for the first time the thrill of seeing the universe's true glory .... its galaxies. That was always the main weakness of Celestia, and you and Toti fixed it.

I agree of course, but what about those beautiful galactic clusters, planetary nebulae etc? ;-) This will unfortunately take until FT2.x (the next major FT version)

I wanted anyone buying the CD (or downloading my Activities for free from the web) to have the pleasure of experiencing that ... of experiencing your work!!!! The universe is worth it. It deserves the beauty that you have just built into it!!! If we all have gotten so much enjoyment out of journeying through space, why not share it with as many people as possible?

If I make any money on offering my Activities to schools ... great. If I don't ... so what! For three years, I've been a volunteer contributor to Celestia as a labor of love anyway.

THAT is why I have been pushing you to release FT 1.1.

That's all fine from my point of view (and in addition satisfies a most useful purpose: education & motivation of kids!).

Still it might perhaps be interesting for you, that --as to myself-- I would immediately leave the Celestia community, if the core distribution was one day allocated (in part) to some commercial taget (NASA, promotional,....) .

I don't give a damn about the date. It looks funny to have a comma in it, but if you won't change it ... no big deal! Distance and speed displays are easier to read with commas and they should stay.
There is nothing to change as I wrote.
It's just up to the users of how they prefer the system configuration.

If you can dim down the Milky Way from Earth's viewpoint, or at least give folks the option to do so if they desire, I believe it will better represent the true brightness of the haze of the Milky Way as seen from Earth. If you won't do that either ... I'll live with it.

I did it already for testing. Let's see how we go there.

I "suggest" that you remove the "set Marker" option in Start.cel. In my humble opinion, Celestia should open without a red box centered in the middle of Earth.


That is an important point for the following reason:

Naively YES, we don't need markers they are only disturbing... (still I always have them ON ;) )

But: FT1.2 will come with a neat new dynamical label display that avoids their overlap or overcrowdedness of labels. In this case, you might well only see the location of the sought for galaxy in form of the (red) marker diamond at first. Then after centering the marker (hitting c), by means of SHIFT + mouse L you zoom in : suddenly lots of labels appear and also move out of the screen again while the field of view decreases further. Then, finally that dim target galaxy and its label appear!

Perhaps you can see that with this new important and quite stunning feature, markers might play a new important role.

But until then everyone who dislikes visible markers, can just comment out the command

renderflags {set "markers"}

in the 'start.cel' script . That's really no big deal.

Just for edification and amusement...

Even ol' Brain-Dead Bob can edit the "start.cel" file via Notepad.

If markers are the worst of your bugs, Good Doctor, I'd say that FT1.1 is
a resounding smash hit! :lol:

Well...I've been following this thread with a great deal of concentration I can tell you!
Now that Bob's on board here I feel I may proceed with some confidence!...Sorry Bob but I'm brian dead too! :oops:

Every time I do an upgrade of Celestia I manage to loose something, but as this is a 'stand alone' upgrade I should be safe?

Fridger and Toti and all the other guys working on this should feel chuffed when even I can get this one going! I'm a little excited here.

I'll install tomorrow and let you know...hehe!

I think my system will not be up to the task however:
Celeron 1.8g
256 Ram
GeForce 2

I've no spare cash!
regards...bh.

A GF 2 is not all that bad. I used it for years and since a year it's in my wife's machine. Celestia looks still quite OK on it (with some limitations, of course).

But your memory is too small! Upgrading a bit of RAM (256MB) would for many purposes be useful. Second hand RAM from old machines??

Also this way around: No. There has not been any code forking or splitting of Copyrights. After all, we try to keep Celestia in "one piece" also in the future.

This version can be installed completely alone - and with NO interaction
affecting your current version of Celestia. Believe me, I know this from
experience now. :lol:

Go for it my friend!

I just installed it simply plain and simple into the regular celestia folder, and no problems whatsoever! Even the framerates are good!

Much thanks, toti and fridger! :D

this is getting to be a long thred
as to "how bright the milky way is " it looks cool maby a bit bright but not bad . How about adding a comment in the code pointing to the setting , that is if it is not there allready. That way we can play with it and give some feedback
At the moment i can only work with the code in win xp and have not had a chance to realy look through it ( been bisy with gcc4.0.1)
if anyone has had some luck with 4.0.1 (or some code changes) send me a mail

Hank,

I made it from"scratch". Unfortunately, for reasons of space, in the default distribution there is only a 'castrated' 1k version of the real thing!

I think this is by far the best and most accurate Iapetus texture available. I used /all/ available recent images including Saturnshine (!) imaging, did the cylindrical projections myself and most carefully matched the various texture pieces. The coloration was computer mapped from a (almost) truecolor hires photo from Cassini.

There are other familiar textures where I could immediately point out where there are large misalignments.

Here is an intermediate image to illustrate the location of the saturnshine imaging patch (top right)

Image

Next an illustration of the delicate adjustment process with many cross-checks implemented

Image

There is also a bump-map texture that accurately models the color-imaged smooth ice coverage on the brown surface. Here is the Celestia view:
Image

Here is my original thread with several views of the full-size texture within Celestia. You will also find the URL for my full-size iapetus as a downloadable add-on.

t00fri's Iapetus
The original 2k Iapetus add-on is here:
My 2k Iapetus add-on

Note: None of my textures, add-ons, locations, scripts etc are to be found on the MOTHERLODE!

Galaxies appear in the daytime... It's strange!!!

Post #157by Sui Ota » 16.10.2005, 10:19

Hello,
First, I appreciate FT1.1, what a great improvement!

And...
There is no problem about brightness of the Milky Way or other galaxies and nebulae, but....

Milky Way is still visible when it is the daytime, at the surface of the Earth(and planets or moons with atmosphere)!!!
Image
Milky Way can be seen how dim I adjust the AbsMag of it, or I decrease light gain with [(] key....
I think this may be out of the problem of the monitor settings which is often referred in this thread.
It doesn't occurs in 1.3.2, and even 1.4.0pre6.

About another galaxies and nebulae like LMC or SMC disappear and appear normally, but suddenly as the time flow from night to day or vice versa in the sky.

In 1.3.2 and 1.4.0pre6, these objects disappear and appear with fading.
Though there is great improvemet for galaxies and nebulae in FT1.1, it's a shame that such a beautiful features are missing :cry:

Question: there is 20 degrees in the setting for brightness... Is there a special reason for this or it's just arbitrary?

What do you mean, more precisely, please? Galaxy brightness? At which level: user level or code level? I don't even understand where you get the unit [degrees] from? With the keys SHIFT+( and SHIFT+) you may add up to 100% brightness on top of the default.

I am guessing ...???
