filesystem is case-sensitive. Here are the modifications needed to make
the compiler happy. These are only some include lines rewritten (Io.h to
io.h, Windows.h to windows.h etc.) for version 2.3.7."
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; }
creating subclasses of osg::Array that referenced data
stored an application's internal data structures. I took
a stab at implementing that and ran into a couple of
downcasts in Geometry.cpp. Enclosed is my take at fixing
those along with a simple example of how to do this."
in the DatabasePager. The practical effects of these are to greatly reduce startup time
and the time to load an individual scenery tile in FlightGear.
- From my log message:
Minimize the number of StateSets and drawables that are compiled by checking
if they have already been compiled or will be elminated by the
SharedStateManager.
Move the sorting of the dataToCompile queue out of compileGLObjects
into the man pager run function.
Change the SharedStateManager to use maps instead of vectors."
- Get or set the target number of PagedLOD children to remove per frame.
- Get or set the minimum number of inactive PagedLOD to keep.
Corresponding environment variables have been added too.
The default values reproduce the previous DatabasePager behavior."
"" for all platforms except Cygwin where its set to "cygwin_" and Mingw where
it is set to "mingw_". Updated osgDB::Registry to look for these for the plugins.
Updated the osgintrospection example to search for these names as well.
src/osgDB/FileUtils.cpp to implement the official Windows DLL search
order as described on the page
http://msdn2.microsoft.com/en-us/library/ms682586.aspx . As mentioned,
the search order is now:
1. The directory from which the application loaded.
2. The system directory. (C:\Windows\System32 by default, gotten using the
GetSystemDirectory function)
3. The 16-bit system directory. (C:\Windows\System by default, gotten by
adding "\System" to the path gotten in the next step...)
4. The Windows directory. (C:\Windows by default, gotten using the
GetWindowsDirectory function)
5. The current directory. (".")
6. The directories that are listed in the PATH environment variable. (as
before)
The first four directories are obtained using Win32 API calls, so they
should work correctly even on non-standard Windows installs.
The changes are well commented and should be clear, even to someone
not familiar with the Win32 API.
I have tested in a few scenarios and it works as expected. Serge Lages
has also tested the changes and confirmed they worked as described. I
have not had any other reports though (positive or negative).
I also fixed the issue with a trailing semicolon on the PATH adding an
empty string to the end of the search paths, as this was an
inconsistent side effect rather than a desirable effect. This change
will take effect on other platforms as well, but since it tests for an
empty string in the last item added to the search paths, it should
have no adverse effect.
"
Created a new GraphicsThread subclass from OperationThread which allows the
GraphicsContext specific calls to be moved out of the base OperationThread class.
Updated the rest of the OSG to respect these changes.
Added and cleaned up DeleteHandler calls in osgViewer to help avoid crashes on exit.
Changed DatabasePager across to dynamically checcking osg::getCompileContext(..)
Updated wrappers.
