hyper keys defined already, but these modifiers were missing in
GUIEventAdapter::ModKeyMask, and the EventQueue ingored them as well.
The attached diff/archive adds the missing parts for Super/Hyper
modifier key support.
I'm aware that this might not be supported on all systems/keyboards
out of the box, but decided to submit it anyway because:
- developers are aware of differences between input devices
(Some mice have scroll wheels, others don't. Some have five or
more buttons, some have only one. Some keyboards don't have
numpads, some have AltGr, some don't etc.)
- even if someone relies on Hyper/Super in distributed software,
this is easy to fix and doesn't create lock-in conditions
- while the names Hyper/Super may only be common on X11, they are
just symbol names and not OS-specific
- even though some systems might not offer these additional modifiers
by default, it's likely that all of them have at least 8 modifier
levels internally, so it should only be a matter of OS configuration
to make them work
- having super/hyper available is useful to offer a user ways
to define local key definitions that are safe from collisions with
predefined "official" key assignments"
Introduced code in BoundgingSphere, BoundingBox, ProxyNode and LOD to utilise the above settings.
Added Matrix::value_type, Plane::value_type, BoundingSphere::value_type and BoundingBox::value_type command line
options that report where the types of floats or doubles.
This change has been done to make it easier for OpenSceneGraph users to check out the svn via https
without any conflicts introduced with a http externals.
as not expiring subgraphs quick enough to enable reasonable load balancing.
New version isn't perfect and will need further work, but does at least reduce
the memory footprint by as much as half on test paths on big databases.
The rewritten method no longer uses the the MaximumNumOfRemovedChildPagedLODs
and MinimumNumOfInactivePagedLODs variables so these and associated methods
for accessing them have been removed.
- /** Set the maximum number of PagedLOD child to remove per frame */
- void setMaximumNumOfRemovedChildPagedLODs(unsigned int number) { _maximumNumOfRemovedChildPagedLODs = number; }
-
- /** Get the maximum number of PagedLOD child to remove per frame */
- unsigned int getMaximumNumOfRemovedChildPagedLODs() const { return _maximumNumOfRemovedChildPagedLODs; }
-
- /** Set the minimum number of inactive PagedLOD child to keep */
- void setMinimumNumOfInactivePagedLODs(unsigned int number) { _minimumNumOfInactivePagedLODs = number; }
-
- /** Get the minimum number of inactive PagedLOD child to keep */
- unsigned int getMinimumNumOfInactivePagedLODs() const { return _minimumNumOfInactivePagedLODs; }
key, but it didn't pick up the initial state. So, if NumLock was on for
the OS at startup (LED on), it was still off for OSG. And the first
keypress turned the LED off, and NumLock on for OSG. The attached fix
picks up the state on every FocusIn, just like it was done in the last
commits for CapsLock. The difference is, that the NumLock mask isn't
standardized (e.g. 0x10 for Linux, and 0x80 for AIX), so we have to do
a reverse lookup (::rescanModifierMapping()).
Note that I could not reproduce the problem on my system, but someone
else confirmed it twice on his, and the patch fixed it for him.

and a new scheme for computing the scaling when using autoscale that introduces smooth

local coordiante frame of the particle system, or be in world coordinates.
It sets osgGA's keymask when restoring keys on FocusIn, according
to the state values of XKeyEvent and XCrossingEvent. (These are
the only source for X11's current capslock state that avoids
pulling in the XKB extension.)

osgViewer::StatsHandler and other handlers which allow you to change the
key(s) you would press to get them to do something. Pretty simple change
but useful in our context and possibly in others too."
The win32 pbuffer implementation returned an error unless both the
WGL_ARB_pbuffer and the WGL_ARB_render_texture functions were present.
This was too restrictive, as a pbuffer can usefully be created without
render-to-texture, e.g. for use with glReadPixels. The osg 1.2/Producer
pbuffers worked without RTT, and osgUtil::RenderStage has all the code to
handle both RTT and non-RTT pbuffers, doing a read and copy in the
latter case.
With these changes I have successfully tested the osgprerender example
on a graphics card which supports RTT, and one which doesn't. Plus
tested in my own application.
In order to aid diagnostics I have also added more function status
return checks, and associated error messages. I have included the win32
error text in all error messages output. And there were some errors
with multi-threaded handling of "bind to texture" and a temporary window
context which I have corrected.
These is one (pre-existing) problem with multi-threaded use of pbuffers
in osgViewer & osgprerender, which I have not been able to fix. A win32
device context (HDC) can only be destroyed from the thread that created
it. The pbuffers for pre-render cameras are created in
osgUtil::RenderStage::runCameraSetUp, from the draw thread. But
closeImplementation is normally invoked from the destructor in the main
application thread. With the additional error messages I have added,
osgprerender will now output a couple of warnings from
osgViewer::PixelBufferWin32::closeImplementation() at exit, after
running multi-threaded on windows. I think that is a good thing, to
highlight the problem. I looked into fixing it in osgViewer::Renderer &
osgUtil::RenderStage, but it was too involved for me. My own
application requirements are only single-threaded.
Unrelated fix - an uninitialised variable in
osg::GraphicsThread::FlushDeletedGLObjectsOperation().
