The class gov.nasa.worldwind.examples.applet.WWJAp plet has the following import which cannot be resolved:
import netscape.javascript.JSObject;

I suspect I'm missing a jar file somewhere.

You changed your name, TAG?

This problem has been reported since applets are there... see this thread:

It obviously fell through the cracks. We will look into it.
There are a couple other things with the view and the sky gradient too. Expect a bug fix release soon.

Ok, I found the plugin.jar and that fixed the compile problems. Thanks.

Good job.
After a quick one-minute test of the web start demo I can say that 0.3 seems faster and more responsive than previous releases. However, there is still that issue with tiles loading everywhere but not in the center of the screen...

There are a couple other things with the view and the sky gradient too.

Like this? (see the pic)

Yes, the 'big black hole in the sky' bug is always lurking... something like déja vu in the .net version. I thought i tracked it down but the far clipping plane distance seems to change in unpredictable ways at very low altitude... a JIRA issue has been filed.

[fabrizio.giudici]

Can you please tell us which are the version of JOGL and GlueGen in this 0.3.0? Thanks

[patmurris]

Here is a quick fix for the layers.Earth.SkyGradientLayer 'black hole in the sky' at low altitude.
In render(), edit this line so that it tests > 10 instead of > 100:

   if (this.glListId == -1 || Math.abs(this.lastRebuildAltitude - camAlt) > 10)

I'd bet it is not the last fix for it

Hi Pat,

Launching the JNLP demo, I got something really weird! I briefly saw *something* and then the GL canvas just flipped. Look at the attached picture and the stack dump from my console... I'm copying a small excerpt here:

I haven't had the time yet to check if I can reproduce it with the SDK itself.

Bye bye!

Chiss!
