help blurred picture

[Wim Bodelier]

Hi Guys,

Last week a neighbor introduced me to your program Nasa World Wind and I must admit I was VERY IMPRESSED.

I was so impressed that I downloaded your program (version 1,2c) as wel as the patch 1.2d. I then downloaded almost all of the add on packs and installed everything.

The first startup worked fine, but then….
When I started to zoom in, the program worked OK, aprox up to an altitude of about 100,000 meters. At this point I can see that the program tries to make contact with the Internet.

When zooming in the screen becomes very blurred, and it doensn’t improve no matter what I try or how long I wait.
It als doesn’t make any difference whether I select a country such as Australia (add-on pack) or whether I cross the Tasman Sea to New Zealand, the picture on my screen remains very blurred.
My neighbor can decend to an altitude of about 200 meters, and stil he has a reasonably good picture on his screen.

The only difference between both situations lies in the fact that my neighbor has direct contact with the Internet over a USB modem where as my Internet connection goes over a router (Trust 445A speedlink XDSL Webstation, and most of all my router also has a built in firewall. We both use an ADSL connection.

Both computers are moren than up to date.
Mine is a P4 3,4 Ghz, with Windows XP Home Ed.
256Mb Nvidia Videocard,
512Mb RAM.
Of course DirectX 9.0c and .Net Framework 1.1 are installed.

What I think that the problem is, is the fact that the builtin firewall in my router doesn’t allow the information on my screen to be updated.
If this is the case I need to open a port (Port Forwarding) in my router, but most of all I need to know which port has to be opened.

I encouterd a simular problem with P2P programs such as Shareaza and Kazza, and after opening the correct port everything worked fine.

I’m very desprerate and look forward to hearing from you.

Did you also install Nowak's "Use Proxy" add on for 1.2d?

It sounds like your just not downloading the closer imagery.

You mightn't have selected to view the high-resolution images.

Check this by going into Layer Manager (Tools menu, Layer Manager), then expand the Images tree (click on the +), then expand the High-Resolution Terrain Mapped Imagery tree and ensure that JPL Global Landsat Mosaic is ticked (Visible Bands - Pansharpened) is ticked. To view close up images of US urban areas, untick the JPL one and tick USGS Urban Area Ortho-Imagery. Generally (as I understand it) you should ony have one of these options ticked at a time.

Hope this helps.
