hi!
in my previous mails, i was struggling with meshes not being displayed
correctly anymore. i had finally realized that this happened due to osg
not being localisation safe. see this thread:
http://wxforum.shadonet.com/viewtopic.php?t=8079
even if this issue does not have to do anything with graphics, it can
become quite an annoying problem, if someone (like me) wants to use osg
in an application which supports localisation through c locales. the
problem is that standard c functions like sprintf and scanf are also
affected by the current locale (the decimal seperator is a dot in
english but a comma in german, just as an example), but osg ignores
this. example:
else if (*ptr=='.')
{
if (hadDecimalPlace)
{
couldBeInt = false;
couldBeFloat = false;
}
else
{
hadDecimalPlace = true;
couldBeInt = false;
}
}
i can think of two solutions for this:
- we replace all calls to scanf, sprintf etc with stl alternatives, as
these are not affected by localisation
- or we simply check for the right characters - so instead of simply
checking a a stream for '.', we get the decimal seperator from the
current c locale. more info:

thank you for your patience and please think about it!
