Re: [Opensim-users] Stars in night sky in OpenSim are shapes rather than dots?

Fri, 11 Jan 2013 14:58:44 -0800

I am always getting told by users in secondlife that the one thing they hate on other grids is the graphics and or textures.
The reason for this and this would likely be the reason you see the starts as a shape is the way each graphics card displays graphics to you. No to graphics cards actually display graphics pixels the same way. In fact if you go into mouselook while set in Midday for your sun setting and then look up at the sun youll see two rectangles. Ive tried this on graphics cards from nvidea geforce, ATI radeon (my current graphics card on my desktop) and Intel graphics (same as my laptop's graphics card) and i get that. So its not really a bug or anything its just the way its displayed via your graphics card. Always be sure your graphics card drivers are up to date but not really much you can do about that unless you feel like messing around with the images in the scene code itself.

I wonder if anyone knows the reason that stars in the night sky in
OpenSim might look more like a shape than a dot?

I think this has been the way the stars jave looked for some years in
OpenSim (but not SL), in multiple different viers, so I am not
thinking its a cache issue.

Anyone else spotted this or know the cause?

You are right. I do not think that this is a problem though. I  
checked some photos of stars  
http://www.jb.man.ac.uk/astronomy/nightsky/nskynov12.html (Jodrell  
Bank) and shapes seem more realistic.  Of course even more  
realistic, in an urban environment, is to not see the stars due to  
street lights etc. The budget conscious council has plans to remedy  
this though!

Hello Ai,

I have only seen this when using ATI ( radeon ) video cards.
Are you using such?.. if so that is probably the reason the night sky looks
wierd.

Best regards,

Guy

I spoke to Linden Labs about this a long time ago, I believe this is a
driver issue, do you get same results in Second Life, at the time I noticed
this i was having same problem in SL and OpenSim, and one of the Lindens
seemed somewhat unaware of the issue, and after asking others about it i
recall the answer being its a driver problem with video cards. If you could
test in Second Life that would be great.

I fiddled  with the environment editor under Sun and Moon Settings  
StrBrite. If I increase the star brightness in both SL and OS there  
comes a point where they look like shapes as per Ai's photo. OS  
looks a bit more shapely but it is difficult matching skies. I am  
using an NVIDIA GeForce GT 650M and Firestorm 4.3.1.31155  15-inch,  
Mid 2012 MBP.  At 2.00 (nice dots) becoming more shapely with  
increasing brightness.
