"It's About Time" (AstroClock JavaScript Program)

"Does Anybody Really Know What Time It Is?" You will - after trying out my real-time JavaScript program AstroClock at: http://www.jeffmack.net/astroclk.html . Just enter your (or any) longitude and time zone offset, and you'll know the time in more ways than you probably care to know! :lo...

Re: Problems running on ATI Mobility Radeon HD 4670 graphics

Thanks Fenerit. I think that I changed it at the same time that I changed the anti-aliasing settings in Catalyst (ATI/AMD). What does the anisotropic filter do?

Re: Problems running on ATI Mobility Radeon HD 4670 graphics

Ahhh! On the "IgnoreGLExtensions" syntax question - I just spotted an example with the various object catalogs near the top of "celestia.cfg." Should be the same. Sorry.

Re: Problems running on ATI Mobility Radeon HD 4670 graphics

Fenerit: I had already tried disabling the anti-aliasing options within the Catalyst Control Panel, with no apparent effect either way. But thanks for the suggestion anyway. Thanks for the suggestion regarding the "AntialiasingSamples" setting within "celsesti.cfg" as well. :) Se...

Re: Problems running on ATI Mobility Radeon HD 4670 graphics

OK, Celestia just locked-up again :( - but only after about 25 minutes of traveling around :). Normally it would lock up only after a minute or so. I was "right-click-dragging" the Earth around - fairly close-up. So, now I'm trying it with the resolution backed down to "Medium." ...

Re: Problems running on ATI Mobility Radeon HD 4670 graphics

I think I might have Celestia working now - but it's early yet! :lol: Before I explain, I have two questions: 1) My ATI Mobility Radeon HD 4670 graphics adapter has 1024 MB of SDRAM, so if graphics adapter memory is what imposes the restrictions on image resolution (Low; Medium; High), then I should...

Re: Problems running on ATI Mobility Radeon HD 4670 graphics

OK, thanks John. I wish I'd known more about these cards (ATI/AMD vs. Nvidia) and Open GL before I bought this laptop! :-(

Re: Problems running on ATI Mobility Radeon HD 4670 graphics

John: I tried your suggestions. In the ATI/AMD Catalyst Control Center, I turned off "4x auto," and changed all anti-aliasing settings to "allow the program to set it." Celestia still locks-up on me. :-( Actually I first used Celestia several years ago on an old (year 2000), slow...

Re: Problems running on ATI Mobility Radeon HD 4670 graphics

OK, I just started Celestia, changed my render path to "Basic," did a "Go To" to Amalthea, and began slowly "right-click-dragging" my view of Amalthea. While "right-click-dragging," Celestia completely locked-up (stopped responding in Windows). My laptop's fan...

I'm using the Catalyst driver from the ATI/AMD Website.

Re: Problems running on ATI Mobility Radeon HD 4670 graphics

Thanks "Hungry4info." I'll try to grab a screenshot when I get the chance. In the meantime I'll just say that, prior to my driver update, I would sometimes see flashing streaks in the background while travelling through space. Now, post driver update, I see a gridwork pattern of large, bla...

Problems running on ATI Mobility Radeon HD 4670 graphics

Anyone have any experience running Celestia 1.6.0 on an ATI Mobility Radeon HD 4670 graphics card under Windows 7 64-bit? I'm getting strange artifacts in the textures, followed by lockups of Celestia. I updated the graphics card driver to the most current version from ATI (AMD), and the problems ac...
