Re: New content and interactivity in next Celestia

How about, instead of hiding away object-specific metadata/scripts inside context menus, we expose more info/controls in the hud? This would increase the usefulness of the hud, and also make metadata more accessible to Celestia newbies.

Re: HDR: High Dynamic Range illumination

1. Appearance and dissappearance of stars is a little too sudden. In fact appearance is gradual (but fast), while dissappearance seems completely abrupt. 2. Appearance and dissappearance of stars does nor work the same when the sun is eclipsed behind a planet, and when you move it out of the screen...

Re: SVN Windows Executable

But I did notice that you had to move farther away from the Earth to get some stars to appear. This screen shot is about 544060 km away and some stars are visible. .. This screen shot is about 310720 km away and the stars disappear. On my Mac, I didn't have to move that far away to see stars. I'm g...

Re: SVN Windows Executable

The OGL2 is a little bright if you have a specmap. This is a known bug. The stars also disappear when a planet or moon is in the view. This includes the Sun also. This is NOT a bug, but a result of the adaptive exposure kicking in. Note that for planets with already very low magnitude (e.g., Pluto)...

Re: Bug (osX) on today built

I don't see any of these issues.. it might help if you could try and narrow down the list of addons that could be causing the problem. Do any of your addons use the Timeline feature?

I'm not seeing any shifting in full screen. Are you using Lua tools?

Re: Square stars / no stars in 1.5.0 on Mac ?

Are you sure you meant all Mac ATI cards Chris?

Re: Celestia UI redesign

Dockable panels might be good, but how about tabbed interfaces too? (e.g., the long-forgotten supertab experiment)

Echoing Fridger's sentiments, I personally like Adobe's approach. Hitting the tab key in Photoshop for example instantly hides/shows all tool palettes. Very simple and effective.

Just to clarify, FSAA has been available for other platforms too in the official 1.5.0 version of Celestia (non-Qt4).

Re: Celestia 1.5.1 features

Yes, but with the console celx, don't you have to enter text using the Celestia console? That's inconvenient - no cut/copy/paste, no autocomplete for script commands etc

Re: Celestia 1.5.1 features

4. Okay, now my ideas are really running wild: What about an integrated plain text editor in the new GUI that could be called upon? Not quite the same idea, but an "immediate mode" script interpreter might be a nice idea. Type in a script into a editor inside Celestia and the script commands execut...

Re: When selecting fuzzy points or scaled discs stars dissapear

Geometry shaders certainly could be used instead of point sprites. The problem is that only very recent graphics cards--GeForce 8 and Radeon HD--support them. Fully-hardware accelerated support would require such cards, yes. But driver-level support is available even for the Radeon 9550 and better ...

Re: When selecting fuzzy points or scaled discs stars dissapear

I've been somewhat out of the loop, but apparently there have been multiple reports on the Mac recently too (Leopard 10.5) that the latest OS broke point sprites, so there's some independent confirmation there. Could geometry shading provide the equivalent functionality of point sprites? I think wha...
