Hi,
I've just pushed some model-loader tweaks, to support the same 'no preview'
tags which FGRun supports, for viewing models. Currently only 'fgfs --fgviewer'
mode sets the requisite flag, 'fgviewer' probably should but I need to check
with Mathias what's a suitable way to control it, since I guess always-on may
not be desired.
The changes hide / omit mesh objects which are tagged 'nopreview'; especially,
Rembrandt-related lighting volumes are skipped. This is important since
otherwise the light volumes confuse osgViewer's bounding-box computation, and
hence the rotation centre and initial scale of the model are very wrong.
With the changes, --fgviewer mode is usable again with the c172p, f-14b at
least.
Now, the big question - I was looking at this to restore the Mac launcher's
preview mode. I could cherry pick these commits to the release branch, but I
want to be cautious, since the model loader is kind of fundamental :) All the
code is guarded with an 'if (previewMode)', so I am reasonably confident it
can't regress anything else.
Or I can wait until 2.10 is out, and then cherry pick to the branch to make a
2.10.1 for Mac with working preview mode - that would be the paranoid solution!
Comments / feedback?
