Apologies for that, apparently our datacenter experienced some type of power failure that then caused some issues with our storage system.

I updated the WWJ to 1.5, and replaced some Polylines with SurfacePolylines. After doing these, I started to see some flickering around the globe time to time.

I examined the code and saw that it contains the sun shading code from the now-obsolete experimental sun shading example, dating back to 2011. Thus, it uses the custom RectangularNormalTesselator. I replaced that with the default one and the flickering disappeared. But this approach disables the sun shading completely.

Is there another approach now to have a sun shading? A gradient filled circle might even be OK, but again, filling gradient is not also possible with the default options. Or, should I examine and try to fix the RectangularNormalTesselator to prevent these flickers? Any suggestions to what I should I look for? ]]> Development Help nerduban http://forum.worldwindcentral.com/showthread.php?t=39102 http://forum.worldwindcentral.com/showthread.php?t=39012&goto=newpost Thu, 13 Jun 2013 17:34:26 GMT I am going to be putting together some machines... I am going to be putting together some machines that will be dedicated to running a World Wind based user interface. Is there any benefit to getting a business workstation class Quadro video card versus a standard desktop card?

I know the Quadro series is designed for business applications like AutoCAD. Does that translate into any benefit for World Wind and open GL?

I appreciate any insight you have. ]]> WorldWind General jonathanknez http://forum.worldwindcentral.com/showthread.php?t=39012 http://forum.worldwindcentral.com/showthread.php?t=39010&goto=newpost Thu, 13 Jun 2013 16:18:34 GMT Any objects that are beyond the horizon are...

I view the entire earth; I don't need tilting or zoom, so I've disabled those features.

I want to set some kind of "marker" at several locations on the earth. I prefer not to use rigid shapes like Cone because 1.) I want the marker's appearance to be somewhat suggestive of what it represents and 2.) I don't need a 3-d object.

I created a png of an image that has the appearance I want, and I'm putting that in a SurfaceIcon to place it on my map. All this works almost perfectly. The one problem is that the image of markers near the poles are quite distorted: stretched in the horizontal direction.

How can I place an undistorted image onto my flat map? Is there a way to scale the image in the horizontal direction? Is there a better way to achieve my goal?

I need to ensure the color values are not altered when a sub-raster is created. Unfortunately, BufferedImageRaster.getSubRaster() uses a bi-linear interpolation which alters some of the colors.

It would be nice if I could pass in my own AntiAliasing and Interpolation rendering hints for BufferedImageRaster.drawOnTo(canvas) to use. Perhaps through the AVList params mechanism.

For a workaround, I had to override a number of classes in order to to create a customized BufferedImageRaster with an overridden drawOnTo(canvas). It works, :), but it was somewhat to implement. ]]> Development Help bdschubert http://forum.worldwindcentral.com/showthread.php?t=39006 http://forum.worldwindcentral.com/showthread.php?t=39005&goto=newpost Thu, 13 Jun 2013 09:23:04 GMT I'm drawing some SurfacePolylines using many points on the ground, something around 600 points for each. I also recreate a new SurfacePolyline whenever it crosses the international dateline. However, this results in some performance degredation, especially when I zoom in closely to the ground.

I replaced SurfacePolyline with Path, and at first look it had a better performance. My question is, what is the essential difference between a Path and SurfacePolyline? Does Path have any shortcomings compared to the other? ]]> Development Help muammer http://forum.worldwindcentral.com/showthread.php?t=39005 http://forum.worldwindcentral.com/showthread.php?t=38992&goto=newpost Wed, 12 Jun 2013 13:43:00 GMT Hello All,

I'm trying to write a generic method that will save out out a renderable object as a JPG or some other image format. I am however stuck.

Is this possible, and if so does anyone have any idea how I'd go about implementing this?

Thanks!

Is there a way to get the Mercator view without having all that area cut off? ]]> Development Help KurtZachary http://forum.worldwindcentral.com/showthread.php?t=38986 http://forum.worldwindcentral.com/showthread.php?t=38982&goto=newpost Sun, 09 Jun 2013 09:30:46 GMT Hello Everyone, I want to load an animation...
