The texture in data/Images should be copied to osg-data. I created the texture myself with the help of an explosion generator, so no license issues there.

, interpolating through HSV space gives a rainbow color effect which
does not mimic the simple RGB color interpolation that OpenGL does.
It's overkill and causes unexpected visual artifacts. In the attached
files I've removed the conversion to HSV so that interpolation happens
in RGB space."
osg::GraphicsContext, in order to give good integration with the
application's GUI toolkit. This works really well.
However, I need to share OpenGL texture resources with the standard
osgViewer GraphicsContext implementations, in particular the
PixelBuffers. This is essential for my application to conserve graphics
memory on low-end hardware. Currently the standard osg implementations
will not share resources with another derived osg::GraphicsContext,
other than the pre-defined osgViewer classes e.g. PixelBufferX11 is
hardcoded to only share resources with GraphicsWindowX11 and
PixelBufferX11 objects, and no other osg::GraphicsContext object.
To address this in the cleanest way I could think of, I have moved the
OpenGL handle variables for each platform into a small utility class,
e.g. GraphicsHandleX11 for unix. Then GraphicsWindowX11, PixelBufferX11
and any other derived osg::GraphicsContext class can inherit from
GraphicsHandleX11 to share OpenGL resources.
I have updated the X11, Win32 and Carbon implementations to use this.
The changes are minor. I haven't touched the Cocoa implmentation as
I'm not familiar with it at all and couldn't test it - it will work
unchanged.
Without this I had some horrible hacks in my application, this greatly
simplifies things for me. It also simplifies the osgViewer
implementations slightly. Perhaps it may help with other users'
desires to share resources with external graphics contexts, as was
discussed on the user list recently."
Notes from Robert Osfield, adapted Colin's submission to work with the new EGL related changes.
filenames starting with a dash "-" character from the (std::vector<std::string>&) version
of osgDB::readNodeFiles. Handling of argument strings is properly implemented in the
osgDB::readNodeFiles(osg::ArgumentParser& arguments,const Options* options)
variant, which most code uses. The (std::vector<std::string>&) version is only called by
the osgconv utility, which does its own argument handling and stripping prior to calling
readNodeFiles().
Also, documented this behaviour in the header comments.
I believe this code removal is a meritful change because leavign the code in causes an
unexpected and undocumented behaviour (ignoring any filename starting with a dash) that
could bite users in the future. This behaviour is not needed for existing functionality
because existing code uses other APIs to handle dash-prefixed arguments anyway.
"
only create 376, then the program would hang.
376 * 8MB stack per thread = 3008 MB
The stack size allocated per thread blew the process address stack.
To get more threads you have to specify a smaller per thread stack,
but while the Thread::start says it will limit the stack size to the
smallest allowable stack size, it won't let it be smaller than the
default. I included the limits.h header to use PTHREAD_STACK_MIN as
the minimum stack size.
As for the deadlock, if the pthread_create failed, the new thread
doesn't exist and doesn't call threadStartedBlock.release(), so the
existing thread deadlocks on threadStartedBlock.block(). Only block
if the thread was started."
I've needed to run a recorded simulation offscreen and save it to a sequence of images, and the ScreenCaptureHandler seemed to be the simplest way to do that, and with this change it's possible.
Another change: I've also added the ability to specify continuous capture of all frames, or a certain number of frames. ScreenCaptureHandler now has a setFramesToCapture(int) method. The argument will be interpreted as:
0 : don't capture
<0 : capture continuously
>0 : capture that number of frames then stop
I also added startCapture() and stopCapture() methods so that user code can start capturing (either continuously or the given number of frames) at a given point in their program. setFramesToCapture() won't start capturing, you have to call startCapture() afterwards. The handler also now has another key to toggle continuous capture (defaults to 'C').
Note that continuous capture will of course only work if the CaptureOperation writes to different files (for example, a WriteToFile with SEQUENTIAL_NUMBER mode) or does something different each time... Otherwise it will just overwrite of course. :-)
I've also taken the chance to refactor the addCallbackToViewer() method a bit too, since finding the right camera is needed in two places now.
I've tested all cases (I think). If you want to try, in osgviewer.cpp and replace the line
// add the screen capture handler
viewer.addEventHandler(new osgViewer::ScreenCaptureHandler);
with
// add the screen capture handler
osgViewer::ScreenCaptureHandler* captureHandler = new
osgViewer::ScreenCaptureHandler(
new osgViewer::ScreenCaptureHandler::WriteToFile(
"screenshot", "jpg",
osgViewer::ScreenCaptureHandler::WriteToFile::SEQUENTIAL_NUMBER),
-1);
viewer.addEventHandler(captureHandler);
captureHandler->startCapture();
And vary the "-1" (put 0, 10, 50) and then use the 'c' and 'C' keys and see how it reacts.

DisplaySettings now define COLOR and DEPTH as defaults for implicit buffers. Consequently Camera by default uses the same defaults through USE_DISPLAY_SETTINGS_MASK. However, particular Camera mask can be easily overriden through Camera::setImplicitBufferAttachmentMask method. I hope, that in this way we can have global control over implicit buffer defaults, and we can still retain fine grained control at Camera level.
I have also replaced original unsigned ints used to store masks to signed ints because complier resolves enums as signed integer (I got a number of warnings with unsigned int)."
Most notable the __hpux define stuff. The __hpux__ variant seems to be not
defined which resulted in a compile error at this time. Consequently I have
replaced all occurances of __hpux__ with __hpux. And huge surprise: now osg
plugins are found and loaded correctly ...
The next notable one is the MSVC_IDE fix which makes the nmake Makefiles cmake
generator target behave like the ide one. Showed up because I started to do
scripted builds with nmake instead of devenv...
The rest is the usual bunch of stuff that just happens during normal
coding ..."
