Help Java3d

[Snah Clouse]

why creating sphere(637f,Orimitive.GENERATE_TEXTURE_COORDS, 800, app) makes memory heap error? hmmm

I need to make earth sphere(6378.137,...., <2000?>,app) & make it possible to zoom in & still get nice view (round)

Is there other way then using sphere to make it work?
Any links to java3d sites with demo code will make me happy

Thanks
