Re: [osg-users] [osgPlugins] Collada Plugin problem with SketchUp exported models...
Hi,
the current Code 2.9.9 uses daeReader::findInvertTransparency to determine
transparency inversion. I am currently facing issues with missing transparancy
on some of the objects I am exporting from SketchUp. Though I dought this is
the issue, I was wondering if daeReader::findInvertTransparency is still the
right approach. Or maybe strictTransparency should override invertTransparency?
Now (2.9.9) the code in daeReader::processTransparencySettings reads:
Code:
_invertTransparency = findInvertTransparency(database);
But maybe it should read?:
Code:
if (_strictTransparency) {
_invertTransparency = false; // already the default, but hey...
} else {
_invertTransparency = findInvertTransparency(database);
}
Hope this helps!
Cheers,
Florian

Re: [osg-users] [osgPlugins] Collada Plugin problem with SketchUp exported models...
Hi,
OK, this works for me, I could do a submission at some point.
My knowledge is:
1. invert for Google SketchUp = 7.0
2. don't invert for Google SketchUp = 7.1
3. findInvertTransparency does not always yield correct results
Something along the lines (code for determining version not included):
Code:
// _strictTransparency overrides determining _invertTransparency
if (_strictTransparency)
{
_invertTransparency = false; // already the default,
but hey...
} else
{
// determine by authoring tool if known, otherwise use
findInvertTransparency
if (_authoringTool == GOOGLE_SKETCHUP)
{
// Google SketchUp 7.1 is known to require
inversion
if ((_authoringToolVersionMajor = 7)
(_authoringToolVersionMinor 1))
{
_invertTransparency = true;
} else
{
// Google SketchUp = 7.1 is known to
be fixed (7.1.6860 to be exact)
_invertTransparency = false;
}
} else
{
_invertTransparency = findInvertTransparency(database);
}
}
Let me know what you think.
Cheers,
Florian
