Re: J3D Properties Settings

Don,
Thanks for your reply. I have added the code to the Plug In constructor but then get a NullPointerException in PilotLoader.getGUI() which is due to timer being null so in the constructor for PilotLoader, I have temporarily put the line
timer = new Timer(1000, this);
Obviously, that will need to be clarified from your end.
The navigation controls work fine. I have attached a partially navigated 3D view to show you what my 3D world looks like. I'm using your properties file with the 3D additions, so I'm centred over Mass., I guess.
Just a quick question, what is the curtain for? A kind of fogging?
Just do you know what I'm running:
Windows 98, J2SDK 1.4, Java3D 1.2.1_04 (DirectX), OpenMap 4.5
I've no idea what the problem is - any help would be most appreciated.
Best regards,
Dave

HI Dave,

I think you have it right, the only thing I'd change is:

to

pilotPathPlugin.class=com.bbn.openmap.plugin.pilot.PilotLoaderPlugIn
pilotPathPlugin.prettyName=Pilot Path

and forget about setting the plugin explicitly. The LayerHandler will
do the right thing for the plugin and the PlugInLayer.

Now this is weird. Looks like the layers are loading into the
MapContent properly, and in fact you are getting the sea and the
"curtain" around the scene. I'm not sure why the political boundaries,
graticule and drawing tool layer graphics are not there.

The PilotLoaderPlugIn doesn't need to be used in conjunction with the
OM3DViewerLauncher, they are separate things.

Can you move around in the 3D scene using the arrow keys?

Ho- Geez!

I did some last minute cleanups getting rid of what I though were unused
leftover methods left over from the adaptation from the graphicLoader
package. In the GraphicLoaderPlugIn, the loader gets set in
setDTEDFrameCache(), and I deleted that method not realizing that the
loader was getting set in PilotLoaderPlugIn there, too.

I think you can add

loader = new PilotLoader(this);

to the end of the PilotLoaderPlugIn constructor methods.

Dang.
Dang.
Dang.

This still doesn't answer why the stuff above isn't working, though.
