Sun shading and Atmospheric scattering

Chris has added atmospheric light scattering to SVN, and boy it looks gorgeous. I posted some screenshots and videos on my blog http://bullsworld.blogspot.com/

Where can we download the altest test builds? http://builds.worldwind.arc.nasa.gov/status/ doesn't seem to be working?

Build servers have been down a while since the switch to .Net 2.0

You will have to download the source and compile it yourself.

Be aware though that the current development version is very broken in the download deparment.

It looks damn good

I can imagine Chris not doing what is urgent and coding like mad that intricate piece of code to take a break in mid summer...

Hiy a Pat,

Any new work on the Java Low Feature version ?

I have been wondering.... It seems that 1.4 was much more stable when I got it in august than it is now.

Many of the height, placename, and download features are horrible right now. I have not touched that code at all, and ther are placenames floating in space, 3D images that are horribly skewed, and downloading is pretty much impossible.

Why so many new problems? I love the WW product and you guys have done a great job, dont get me wrong.

Screenshot is with VE set to 3, so that isnt the problem.

That i believe is the new and horrible zip based SRTM server that they need for the Java version. Otherwise we have some very lovable features such as 3D models and better KML. Try the 1.4 stable branch in the SVN. The downloads in the trunk/head are broken.

You know how i like nice visuals... so using some code from the Sky Gradient plugin, i spent some time fixing the 'not-so-nice' artefacts that were spoiling this beautifull addition to WW. Here are some screen shots of the now seamless atmosphere from the coming WW 1.4 RC2 (or release ?) :

Tenerife, Spain with sunset

Mt-Fuji, Japan, daylight

Himalaya, facing sun

Sunrise from space over Europe

Chris made a nice piece of code computing the whole process of light scattering. With a better mesh geometry it now shows all its glory - with CPU processing only though.

If only those damn beautiful sunsets would be just a little different from place to place... maybe we could use the Global Clouds images to add a little variation

.

I also ironed out the terrain shading seams that where showing between the tiles... The sun shading brings out the most of topo and geology maps and will make a lot of happy new users. I cant resist to share some of the great shots i took while testing :

USGS Topo, Glacier National Park, USA, sun shading and atmospheric scattering

USGS Topo, Glacier National Park, USA, with sun shading

The same views without shading would be unreadable!

The nice thing with USGS Topo maps is that they are quite detailled. They do bring out the most of SRTM data in the US - more detailed terrain geometry than with Lansat layers.

WW 1.4 will hopefully draw some attention with such goodies
