Re: Celestia 1.7.0 Development Thread

@john71, I don't know what you are trying to say with the "chin scratching" emoticon. My dilemma is this: you experienced the same lagging problem, but you did not have a lot of addons eating up the resources. So it seems that the problem is not a data handling error, it is another kind o...

The Milky Way is not flat!

I found this article. We should correct Celestia to achieve this new warped and twisted shape.

Re: Celestia 1.7.0 Development Thread

From Your description, this problem concerns planets, moons and 3d models, not stars. In my opinion it is not a direct OpenGL or graphic card problem, it is an internal data handling deficiency, caused by many-many GBs of ssc, stc and texture, mesh data. So I hope it won't effect the handling of th...

Re: Celestia 1.7.0 Development Thread

You can recreate the problem easily: use the 64k Earth textures (surface, bump, cloud, night etc.), copy the Earth data to create 3 identical Jupiter moons (SemiMajorAxis 1, 1.5 and 2 million kilometers) and experiment with it. My whole star system is 21GB, so I cannot share it. In my opinion Celest...

Thank you. I've been saying this for months.

Added after 1 minute 36 seconds:
I think the developers should officially release the 32 and 64 bit win (non-QT) version as Celestia 1.7.

Janus wrote:Actually, QT takes over opengl handling with its own routines,

I'm not a programmer, but my instinct tells me the same. The qt version behaves differently, than the win version.

So it must be some kind of internal qt property or unintentional error. Qt runs opengl differently.

Re: Celestia 1.7.0 Development Thread

Are You sure option Display -> Fps is set to Auto? Yes, but the fps rate is lower, than in the win version. Usually 13-21, which is - in my opinion - not acceptable in an official release. Consider this: first I sensed the low fps problem without any concrete fps monitoring. It is simply annoying. ...

Re: Celestia 1.7.0 Development Thread

I think you should make an official, downloadable release named Celestia 1.7 with an exe file. This is an usable version and Celestia 1.6.1 is 32 bit only AND very old. So please make it official. It would be very nice to have a clean 1.7 installation with an exe file... New rendering features can b...

Whoa, the win version works perfectly for the first time! Every moon and mesh is visible! Nice!

The fps rates are also good! :clap:

Janus, What I cannot comprehend is that THERE IS a lot of FREE CPU power, bandwidth, RAM, GPU power and yet Celestia is not capable using any of it. :insane:

Re: Celestia 1.7.0 Development Thread

Janus, 8-12 fps on the same spot with my add-on star system, otherwise 50-60 at the Solar System.

Added after 3 minutes 12 seconds:
It seems that the presence of lot of objects, large textures and meshes are causing the problem, but Celestia cannot use the hardware to compensate. :think:

Re: Celestia 1.7.0 Development Thread

onetwothree , OK, I checked a few things in the last commit. 1.) the arrow keys are indeed working in the last version. When I wrote my post yesterday, I had several versions of Celestia running at the same time. That was the probable cause of the not functioning arrow keys. :eek: 2.) the fps monit...

Re: Celestia 1.7.0 Development Thread

pirogronian, Not really, I mean if I want to create/write or correct an ssc file, it would be nice to have an integrated approach. In that way you could see the results inside Celestia right away.
