Problem with drawing multiple Spherical Domes

Hi, I am currently working on drawing some 3D geometry into WW. I am using the Sphere class to draw domes on the earth surface. However, I encounter the problem that when drawing multiple domes, only the first dome will turn out right (as a half sphere) whereas the rest of the domes appear as spheres even though the elevation is set to be at ground level. Is this a WWJ bug or have i done something wrong?

Some screenshots and code would help answer your question...

Hi, I just registered my account. Attached is the screenshot from my testing of drawing domes.

public Renderable renderDome(Dome _dome) {
gov.nasa.worldwind.Globe _globe =  new gov.nasa.worldwind.globes.Earth();

gov.nasa.worldwind.geom.Point _domeCenterPt = _globe.computePointFromPosition(
				_dome.getCenterPosition().getLatitude(), _dome.getCenterPosition().getLongitude(), 
				_globe.getElevation(_dome.getCenterPosition().getLatitude(), 
						_dome.getCenterPosition().getLongitude()));

Sphere _domeShape = new Sphere(_domeCenterPt, _dome.getRadius(), _dome.getColor());

return _domeShape;
}

The above function returns a Sphere instance. Which is then added into a renderable layer for display in the actionPerformed method of a command button.

I solved my problem already. Apparently, I made an error while modifying the render() code of the Sphere class in order to make it possible to set the color and transparency of the Sphere.

I quickly looked into your issue and the code looks right.
Except maybe the getElevation() that will probably not return a very accurate value at startup - before elevation data gets cached.
For better placement, you would probably need to update the elevation component of each dome center, whenever better elevation data is available.
