I had sometimes such problems. However, constant fps issue I noticed only on my astrodb branch.

I have Intel Core 2 Duo & nVidia GeForce 8600GTM, no addons, stars mag limit 7,9.

Re: Celestia 1.7.0 Development Thread

I'm asking if the astrodb code allows for catalogs of stars outside of the Milky Way. Precisely in the same way as inside Milky Way. And the same for other objects, even whole galaxies. UID is object-type agnostic. The only thing we must care on is unique assignation of UID by Celestia data maintai...

Here is a goot indication of changes I made while integration. Just search for files in qt subdir.

Re: Celestia 1.7.0 Development Thread

Is there a guide to the changes you have made for the new 'astrodb' database API? I ask because I will not be using the QT version even after the change over happens. Which means I need to make the VS/windows version work with it. There is no guide, but probably should be. But as the code is still ...

Re: Celestia 1.7.0 Development Thread

I hope that someone makes the database load in distance order so a spherical map can be maintained. This would enable the user to limit how many stars are loaded by setting things like max memory to be used. Something like this is a primary reason I started working on Celestia at all :wink: When fi...

Yes, You can :wink: Backward compatibility is one of main goals. So, no changes should be need in any file. Currently all original data files seems to be parsed and loaded without errors.

Re: Celestia 1.7.0 Development Thread

Despite that, there'll still be a universal object identifier catalog like the proposed Celestia Catalog right? Of course. User-defined catalog means, for example, we may let user to register Gaia catalog with prefox/name GAIA and name pattern { "GAIA %i", <gaia_nr> }. Then user would be ...

Can I get a brief summary of what the current plan (and status) is with the database restructuring? Done 1. Fully implemented dynamic loading and searching of stars and DSOs. 2. Fully implemented dynamic reflection of changes of position and magnitude of stars & DSOs in octree structure. 3. Ful...

Re: Celestia 1.7.0 Development Thread

Is it like we can type any number or letter value in any order we wish when we designate such objects? Like for example, typing "uihfdhf" can be used as an identifier? No, it have to be non negative integer. For use it for Gaia catalog, we have to create new cross index with mapping UID <...

More precisely, ids beyond 0xf0000000 may be bound to Gaia numbers via cross index.

Re: Celestia 1.7.0 Development Thread

With regards to astrodb, can starnames.dat allow identifiers other than HIP and TYC or is that still in development? Yes, astrodb allows for any numeric id for astronomical object. But for backward compat there are two rules: 1. Id less than 999999 is interpreted as HIP nr. 2. Id between 999999 and...

I think it may be related with cross index.

Yesterday I fixed with some trials and errors, the blinking problem. If You used last snapshot, it should contain my fix.
