[osg-users] PagedLOD range for 2D image tiles

[Bruno Oliveira]

Sorry, my mistake. No FOV in Ortho2D projection, obviously!

I tried that setRange(id, 0.5, 2) and it did not work, no tile is ever
rendered..

Notice that my tiles are added to the scene graph as geodes, with size =
tileSize / scale,
hence, a tile is always 256 pixels, but the geode size is set to world
coordinates as the size that tile occupies in the whole image frame
coordinates.
