Celestia Forums

I was able to ask the AI deepseek coder v2 on my PC to analyze the winmain.cpp file. The 41231 tokens code was analyzed in little over 10 minutes. It replied this: The code provided is a Windows front-end for the Celestia application, written in C++. It handles initialization, window creation, OpenG...

You should try them. They are fun too. I was able to get a working Python script on my first try just by describing it with logical sentences. OK, it is true, you have to be very precise, but the AI wrote 3 pages of code just by using my sentences. ChatGPT4o is the best. Also you can use AIs on simp...

ChatGPT, Claude and other AI tools can create almost any code using simple sentences as instructions.

AI can search for errors in the code.

Are the developers of Celestia using this free method to speed up the process?

That's true. That is why I used visible light images for VT layers at 16k, 32k and 64k. THEMIS is perfectly in sync with them at 128k and 256k and THEMIS can show unbelievable details.

But it has a 100 meter resolution so if you want real details there is no other data source.

I made a 256k false color dds Mars surface map but it is 38 GB. I used the Mars Odyssey THEMIS-IR data.

Olympus Mons:

OK. Now I can prove, that it is a software bug:



60 fps when there are not too many objects around.



Fps drops dramatically when there are planetary rings around (but why?).



Fps literally dies when the planet feature is on.

I found this text: https://www.mail-archive.com/interest@qt-project.org/msg36622.html Hi, I'm using a third party library (Skia) to render custom opengl code in sync with the QtQuick Scene Graph (Qt 5.15 on Windows 11). I'm using the QQuickFramebufferObject and QSGRenderNode classes to create custom...

Qt is slow for many others, so there must be a reason. Maybe more cpu resources. Gpu resources, whatever. That's a good lead. Celestia 1.6.2.2 consumes 15-25% of the GPU resources. Celestia 1.7 win32 is between 15-30%. But Celestia Qt can reach 40%. And where? At Mars, when the fps is very low. But...

If he already has one it may be failing. So my PC's power supply is failing at Celestia Qt, but it is not failing at Celestia win32? Not likely. As for system settings, I have the computer's power management set to "performance" mode. Thanks for the tips. The problem is that Celestia Qt C...

With Qt?

Maybe OpenGL and Qt has some kind of problem?

Maybe the problem is in the registry. Are they separated there?

Quite the opposite: every unnecessary file was purged by Bleachbit after I deleted every Celestia folder.

That's why I suspect that reinstalling 1.6.2.2 changed something...

I just purged all unnecessary registry data and uninstalled all Celestia versions a few weeks ago.

AND after that I installed your exe file.

I have 4.6.0 GL version. My card was able to achieve 820-941 fps with this test: https://sourceforge.net/projects/openglchecker/ I read about one person who had low frame rates cleaning the card contacts and reinstalling it to get rid of their problem. Also maybe you should take a look at BIOS setti...

Built it myself from parts.

Has no problem with high end PC games.
