47bbe8f3cc Fixed the osgDB::getFilePath, osgDB::getSimpleFileName() and osgDB::getStrippedName() 
so that they check for both unix style '/' and windows style '\' slashes in
file names.

fa13d948b5 A little more work on Occlusion culling. 2002-06-11 19:52:55 +00:00
Robert Osfield
247cb3ff7e Checked in Macro Jez's additions to osgText to support .osg IO make it 
a fully functioning NodeKit.

Also reimplement notify() to try an prevent a crash which has been caused by
to objects in notify.cpp being initiliazed twice, the second time the auto_ptr
holding the dev/null ofstream was being initilized to 0.

e1ba8a6292 Added osg::CollectOccludersVisitor which is a helper class for finding active 
occluder in the view frustum, to be used as pre cull traversal.
 2002-06-10 13:50:25 +00:00
Robert Osfield
348419219d Created new helper class osg::CullStack to handle the accumulation of projection, 
modelview and culling sets, to be used during travesal of the scene graph, such
as the cull traversal.

Robert Osfield
d91b848a63 Checked in migration from osgUtil based GUIAdapter code to Neil Salter's 
osgGA (Gui Abstraction).  This may break users code, but all it should
require to fix the builds should be a change from
osgUtil::CameraManipulator (etc) to osgGA::CameraManipulator and
include <osgUtil/CameraManipulator (etc) to osgGA/CameraManipulator and
the extra dependency of the link line.

Robert Osfield
bf6bf60e21 Added osgoccluder demo, it creates a single quad occluder, but the culling 
code is not complete yet, so it won't actually do any occlusion culling,
the demo is here so I can test the evolving occlusion culling code.
 2002-06-07 20:03:08 +00:00

e66372a137 Fixed problem with orhographic projections due to a bug in CullVisitor 
where it automatically resets the near and far to the values calculated
during cull traversal.  The maths for converting the computed far and near
into clip coordinates was wrong, fixed this and the problem goes away.

d140decb44 Added pixelSize method to CullVisitor, and converted small feature 
culling to use the pixelSize method instead of a ratio of radius to
distance from eye point.  setSmallFeatureCullingPixelSize() method
has also been added to provide the user with finer control of small
featyre culling.

117e3c2304 A more verbose version of the test script, using each and more memleaks.log 
to print out progress and report any memory leaks which have been logged.
The later will only occur with a debug build.  The use of echo and more
makes this version osgtest.bat not portable to windows unfortuntately.

61b0865309 Merged Bob's changes for MacOSX build. This change is simply the addition of 
GLUT_LIB to the link line.  This change should be removed once we fixed the
OSG_LIBS so that it doens't include osgGLUT, however, I'll leave this for another
day...

Robert Osfield
b2e6279178 Removed the use of __FUNCTION__ from MemoryManager to remove problems with 
VisualStudio .NET compile.

Added support for OSG_NOTIFY_LEVEL and OSG_FILE_PATH into the relevant getenv
routines.  This compliments the exisiting OSGNOTIFYLEVEL & OSGFILEPATH which
are deprecated but still supported.  The OSG_ version are more consistent
with the rest of the env variables used in the OSG.

3668c050da Seperated out the platform specific implementions of the file search/access 
routines - we now have FileUtils_Windows.cpp, FileUtils_Mac.cpp and
FileUtils_Unix.cpp.  The FileUtils_Mac.cpp is based on code submitted
by Josh Portway and add uses the carbon API for searching for files.

Robert Osfield
2d0df88ee4 Added an imageList.clear() to osgbillboard so that its memory would be 
cleared before entering the viewer main loop, this removes memorymanager
a reported memory leak due to the viewer using exit() which bypasses
the clean up on main itself.

Added an osgNew to the ReaderWriterRGB.cpp to aid detected of tracking of
memory leaks.

56dc083330 Added support for compute the near and far planes and then applying to 
the current projection matrix into CullVisitor itself.  Similar code to
support this has been moved out of SceneView completely.

Added Matrix:: infront of the definition of the static
osg::Matrix::inverse(Matrix) method which was missing.
 2002-04-22 14:54:39 +00:00
Robert Osfield
f515d67f4f Cleaned up the handling of the Viewport with osg::SceneView/RenderStage 
and CullVisitor so that the Viewport is now managed as part as the global
stateset so that it can be pushed and popped like the rest of state without
problems.  This makes it easier to have multiple viewports within one
scene graph.

Robert Osfield
9574ce97d2 Updated TODO list. 
Converted AnimationPath so it is now subclassed from osg::Transform::ComputeTransfromCallback()
so that it can be directly attached to the scene to move objects about.

Changed the osg::SateSet::setGlobalDefaults() so that is sets GL_DEPTH_TEST
to ON.

Added guards and creation of default helper classes in osgGLUT::Viewer and
osgUtil::SceneView so that sensible defaults are used when no settings
are used of osg::State/StateSet,osgUtil::RenderStage/RenderGraph/CullVisitor.
