Re: [Opensg-users] Crash under Windows 7 64 bit in OSG::exactinit()

[Schaefer J. <Joh...@ip...>]

Hi Ákos,

i am using OpenSG 1.8. Is there any way to disable this method without patching the osg source? I don't use the NURBS code.

Regards,

Johannes

Hi Georg, Johannes,

OSG::exactinit() is only used by the NURBS code AFAIK, so if you don't use that it's safe to leave it out. I don't really like this solution either and was thinking at some point about replacing it, but handling floating point accuracy is tricky. :(

I don't have access to a 64 bit Windows machine at the moment unfortunately so cannot check why it suddenly fails (BTW is it 1.8 or 2.0?), I believe it was correct at the time when we added it. Don't know about 2.0 though, but I'd assume Carsten checked it also on 64 bit Windows, though probably only on XP which may be different to Win 7.

Sorry about this issue.

HTH,

        Ákos
