[Flightgear-devel] problems with z-buffer

[Alex R. <ro...@sy...>]

the latest commit to src/Main/CameraGroup.cxx changed the value of
zNear from .1 to .4 and this causes strange artifacts to show up when
panning around (like holes in the cockpit, etc.). the following patch
changes it back:

     bindMemberToNode(gnode, "near-field", cgroup, &CameraGroup::_nearField,
                      100.0f);

any reason for the change?
