Re: [osg-users] OSG books now on Amazon marketplace
Hi Paul, Hi all -- Just FYI... Lulu has arranged with Amazon to have the OSG books listed, using their "marketplace" reseller listing. This means you can now order OSG books by going to amazon.com and searching for "OpenSceneGraph". Very cool, good for visibility! Great work!

Re: [osg-users] CPU usage
Hi all, I doubt that's the case if he's just running cow.osg. More likely, VSync is not being properly detected on the ATI system, so the viewer is just running free and not waiting for the frame to be drawn on the screen. I think Jason's guess is right on the money. Check your frame rates, you'll probably see that the nvidia system is running at a steady 60/75 (whatever your refresh rate is) while the ATI system is going at several hundred frames per second (500 or more, most likely). I've found the first time I run an OSG app on an ATI card, I have this surprise, so I have to set the vsync setting to forced on in the control center. I just always assume that vsync is on by default, and use ATI pretty seldom, so I'm always being bitten by this one...

[osg-users] animation doc/tutorial
Hi, I recently started looking at the animation part of osg. I have read some examples and wonder if there is tutorial or formal documentation for it. For example, I would like to replace the linear interpolation in the example osganimationsolid with cubic bezier interpolation. It doesn't really seem there is a good way to find out. The online documentation is minimal and with all those templates and definition, it's really hard to find a good place to start with. Can some one help me out? Thank you!

Hi Rabbi,
Please elaborate the crash; is there a C++ exception? If so, what is
it? Did you try to wrap the block with try-catch? STL containers may
throw different exceptions depending on what has gone wrong. You can
do something similar to following:
try
{
// the you suspect to lead the crash
}
catch (std::length_error& le)
{
std::cout << le.what() << std::endl;
}
catch (std::bad_alloc& ba)
{
std::cout << ba.what() << std::endl;
}
catch (std::exception& e)
{
std::cout << e.what() << std::endl;
}

Thank you very much for your help. :-) Good to hear that this issue has for now been settled.

The loss in perspective is that the illusion that RHEL/CentOS and all the other long term supported linux distributions can bundle not only the core operating systems but ten's of thousands of other open source tools as one single supported and consistent entity. No other operating system vendors attempt to do this - they just ship the operating systems and the all the rest of the tools are provided by extra separate entitities and typically provided by 3rd parties. Some of these third party apps might rev at the same rate as the underlying OS, but typically don't. Now it's very cool that linux distributions do attempt this almost impossible feat, but and it is humongous but there are problems with this approach of bundling practically everything together and rev's at the same rate is that in the 3rd party vendors can't be expected to pay for the support for this locked in versions of their software for the benefit of the linux distribution vendors. This very thread is about that fact that CentOS/RHEL have locked in versions of software that is DIRECTLY cause support work for us - not just the CentOS/RHEL users, but others who have nothing to do with developing or supporting this distro's. You might pay RHEL for support for doing this but are you paying all the rest of the ecosystem like OSG community members for the luxury of you using the tools that only come with a particular RHEL. So this is perspective that is missing. It's your companies choice to use a distro with locked in versions of software, and there is a cost of this that goes far beyond your own company. Who's to pay for this? In the case of community like this core developers have to put up with support hassles like this as just part of running a project, but we need help, and help specifically from people who wish to use locked in versions of software due to using CentOS/RHEL etc - you guys need to spend the time in properly supporting software that you need, this means allotting time and resources to help out with testing. For instance we have the CDash dashboard to tracking nightly builds. Also talk with your management about this issue - if you want the luxury of using a fixed version of OS and associated tools then their is this extra cost that you need to factor in, if you don't have the ability to keep track of supported software then you have to pony up the 3rd party support to cover this.

Re: [osg-users] build errors with 2.8.1
Hi John, Try removing your OpenSceneGraph/CMakeCache.text file and the re-run ./configure to see if that kicks CMake into properly checking all the dependencies. Also try disabling the aggressive warnings to see if that prevents gcc spitting out errors when compiling against ITK. Robert.

Re: [osg-users] Image::getColor
Hi Guy,
This would be reasonable change. Once you start looking at
automatically wrapping you should probably start thinking about
passing in the texture wrap mode to enable you to make the same
texture coordindate modulation as OpenGL will do, otherwise you'll
just be hiding a problem.
