why creating sphere(6378f,Primitive.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?
When im doing it on shere(637......) it warks but when i start zooming out
texture stops to scale at some distance, how can i fix it?? (do i have to
make more textures with different size and load them all to memory?, is
there other way?)
Any links to java3d sites with demo code will make me happy
Thanks
code:
