Re: [osg-users] Nasty bug when compiling for Mac OS X or iOS

Hi, the allocate modification definitely works because I already implemented it by myself. For the others I do not have a test case at hand but should work, too. Thank you! Cheers, Hartwig -- Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=62793#627

Re: [osg-users] [vpb] osgdem Colormap gets flipped

Hi Michi, I did some builds with VPB last week and didn't come across any flipping problems with the datasets I was working with. My guess it must just be happening for certain datasets. Could you provide guidance on how you are running osgdem and the data you are using to see this flipping issue

Re: [osg-users] Nasty bug when compiling for Mac OS X or iOS

Hi Hartwig, Looks like you've stumbled across bugs in the C++ std imlementation and the osg::TransferFunction1D. Good work :-) I have had a look at the TransferFunction.cpp and believe the following mods would be appropriate. I've attached the TransferFunction.cpp that I've just modified as wel

Re: [osg-users] Using c++11 smartpointer instead of osg::ref_ptr?

Hi Gianni, Back at my compute with chance with a more detailed reply. I would recommend you look up how the boost and std::shared_ptr are implemented. They actually have a pointer to a reference count shared object that points to the actual object you want to manage. So your object itself doesn'

Moin! Any news to this topic? I built VPB from current sources yesterday and the problem with flipped textures still exists. My DEM and image file are of the same extent and reference system. Loading the DEM alone works fine. When I specify just the image file via -t without any DEM (omitting -d

[osg-users] Nasty bug when compiling for Mac OS X or iOS

Hi, if compiling OSG for OS X or iOS there is a nasty bug in the std::map library. This bug only exists when the C++ language dialect is C++98, GNU++ 98 or when using the compiler's default dialect. Due to this bug assignments like Code: aMap = aMap clear the content of aMap. This bug can oc

Re: [osg-users] Using c++11 smartpointer instead of osg::ref_ptr?

Hi, but isn't ref_ptr too much "intrusive"? I mean, what if I need to write my own class hierarchy of lightweights objects, that can be used both without reference handling in real time applications and with "smart pointers" in a GUI application? I think I can't do that with ref_ptr because all
