all unsed texture units can be turned off simply within Drawables such
as Geometry and GeoSet. This can be used to prevent bleed of arrays from
one object to the next - which can cause crashes.
various
osg header and source files to optional compile in deprecated parts of
the
OSG API.
Have renamed osg::Transparency osg::BlendFunc to bring it in line with
the
rest of the OSG's StateAttribute classes which are named after their
OpenGL counterparts. include/osg/Transparency still exists and is
simply
a typedef to BlendFunc and is enclosed in a #ifdef USE_DEPRECTATED_API
block.
The matrix methods in the osg::Transform class have been
moved/replicated in
a osg::MatrixTransform sublcass from osg::Transform. The old matrix
functionality is still present in the osg::Transform class but is guard
by #ifdef USG_DEPRECATED_API blocks. One should now think of
osg::Transform
as being a Transform Node base class. MatrixTransform has all the
functionality of the original Transform class, so should be used
instead.
it inline with the CullStack/CullVisitor implementation. Also added the
setSmallFeatureCullingPixelSize() method and wired them up inside
SceneView.cpp so they set the corresponding CullVisitor paramters.
Intergrated pfImage copying change in the Performer plugin, submission sent in by Ulrich Hertlein
implementations for all the public functions found in the header,
this should prevent problems when not compiling in the MemoryManager
under IRIX 64 build.
inside the osg::Image::ensureValidSizeForTexturing() method. The
smallest of GL_MAX_TEXTURE_SIZE and OSG_MAX_TEXTURE_SIZE is used for the
final max texture size.
This new env. var. allows users to deliberate cap the size of their textures
so they can test whether their models are limited by texture memory. If
reducing the max texture size increases performance then you are limited
by texture memory!
Added support for osg::BoundingSphere::expandBy*(osg::BoundingBox) and have
added osg::BoundingSphere/Box::valid() which deprecates isValid(), this
is to be more consistent with other classes in the OSG.
the number of occluder that will be used in cull traversal to only the
ones that will be effective. Note. Holes in occluders arn't handled in
this occluder occlusion test, will implement this later.
storage of the path lists into osgDB::Registry, and changed the data
structor from a char* to a std::deque. Changed a names of couple of the
convinience functions in osgDB/FileUtils to better reflect the two
public FilePathList's - DataFilePathList and the LibraryFilePathList.
Added support into the osgDB::Registry::readNode/Image/Object methods
for pushing and popping the path of the current file being loaded.
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.
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.
removal of node which could have been removed.
Added so extra convinience methods to ClippingVolume and utilized them in the
CullVisitor to push and pop only culling planes that are active.
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.
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.
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.
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...
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.
Windows PATH environmental variable for searching for libraries. Sent in
by Norman Vine.
Reoder of the makedefs/makedirdefs to fix Mac OSX compilation. Sent in by
Bob Kuehne.
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.
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.
Supported added for precompiled mip maps stored in osg::Image, and read
by osg::Texture.
Updates to TerraPage loader for support of compressed texture images and
precompiled mip maps.
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.
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.
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.
it conforms to the OpenFlight convention of euler angles. Added documentation
into Matrix and Quat to reflect this.
Added so test code to osgcube for stress testing memory allocation and deallocation.
Commented out the registering of app and cull callbacks in osghud.
modelview matrix rathan than an identity matrix, this matrix is then modified
locally.
Changed the osg::Matrix set methods so they are inline.
Added a few useful comments to MemoryManager.cpp to help people understand
the assert's better.
the DIRS cruft in a single file in the Make directory instead of having
to edit multiple files. Also edited Makefiles that needed to include
this file.
Also cleaned up txp loader to compile with SunOS. This needs to be retested
on other platforms.
renamed osg::Image::pixelFormat(), internalTextureFormat(),dataType() to
osg::Image::getPixelFormat() etc. These changes are to bring it more
into line with the style of the rest of the OSG.
Updated the rest of the distribution to take account for these names changes.
osg::Camrea::getModelViewMatrix() and osg::Camera::getProjectionMatrix() are
calculated on the fly. Removed various redudent methods, including the
project and unproject methods which are better supported within osgUtil::SceneView.
Added a computeWindowMatrix() method to Viewport, to make it easier to construct
a MV*P*W matrix for converting local coords into screen coords and visa versa.
Converted SceneView and CullVisitor to use this new method.
to create the string. Also Removed some in appropriate comments from LongIDRecord, since they
were obvious and hang over of a copy and paste job on the code.
did a check on forcing 16bits textures in osg::Texture (which speeds things
up on the Umea model which is performance bound by texture memory.), the
later check is now commented out.
support out of Camera and into SceneView. Also enabled the option to set the
projection and modelview matrices directly on SceneView thereby removing the
dependance on osg::Camrea to control the view of the scene.
which objects have values that vary over the lifetime of the object (DYNAMIC)
and ones that do not vary (STATIC). Removed the equivalent code in
osg::Transform, StateSet and StateAttribute, as these are now encompassed
by the new DataVariance field.
Removed MatrixMode enum from Matrix, and associated fields/parameters from
osg::Transfrom and osg::NodeVisitor, since MatrixMode was not providing
any useful functionality, but made the interface more complex (MatrixMode
was an experimental API)
Added ReferenceFrame field to osg::Transform which allows users to specify
transforms that are relative to their parents (the default, and previous behavior)
or absolute reference frame, which can be used for HUD's, camera relative
light sources etc etc. Note, the view frustum culling for absolute Transform
are disabled, and all their parents up to the root are also automatically
have view frustum culling disabled. However, once passed an absolute Transform
node culling will return to its default state of on, so you can still cull
underneath an absolute transform, its only the culling above which is disabled.
osg::Image::readPixels to encapsulate glReadPixels.
Reordering of includes in include/osg/Fog and include/osg/Light to remove silly warnings under Visual Studio.
osg::Drawable. Added osg::Image::readPixels to osg::Image.
Made osg::LightSource to default to cullActive set to false to that LightSource
nodes don't get culled by default.
Added a cleaner way to install demo source so that installed versions use a
simplified makedefs/makerules.
Small fix to get osgText to compile with Solaris CC. Constructor declared
with a non-const argument, but implemented with const argument.
library and plugin files that looked like system library and system files
which would have deleted original files on a 'make install'. Cygwin is not
tested yet, but this needed to get fixed before a cygwin user wiped out his
system library files.
Added distrules and makerpms for building RPM distributions
Removed old RedHatRPM distribution build directory
Added new dist/RPM directory and placed temporary .spec files (these
are generated by Make/makerpms and are not intended for stand-alone
use, but they keep the directory warm and CVS happy)
added prefixes and suffixes to libs and plugins. ALl this to accomodate
cygwin...
Also added INST_SYS_PREFIX and INST_SHARE_PREFIX for installation, as well
as "standardizing" the install locations for the various platforms.
the Make directory is left with four files only :
makedefs
makerules
makedirrules
instrules
These work for all platforms supported so far, which include :
Linux
Irix
Solaris
MacOSX
Cygwin
FreeBSD
in progress for the new support for controlling the projection matrix from
within the scene graph.
Also Added osg::State::getClippingVolume(), getProjectionMatrix() and
getModelViewMatrix() with allows drawables to access the current projection,
and model view matrices and the view frustum in local coords to the drawable.
it now maintains references to the last applied matrices, automatically doing
lazy state updating. This simplifies the various places in the OSG which
were previously doing the applying, add paves the way for managing the
projection matrix within the scene graph.
Remove MemoryAdapter and mem_ptr as they arn't being used, and can potentially
confuse users by their existance.
osg::Texture. The values default to 0, and in this state they are
sizes of the glTexSubImage2D are taken from the source image size. This
allows the previous setup with no settings for subload size to work as
before.
memory manager published at flipcode.com. This can be turned on
with the OSG_USE_MEMORY_MANGER option which then uses custom global
new and delete operators as well as provide osgNew and osgDelete macro's
which add ability to log line and file from which calls are made.
Updated osg,osgUtil,osgDB,osgText and osgPlugins/osg to use osgNew/osgDelete,
and fixed memory leaks highlighted by the new memory manager.
published at flipcode. I havn't adopted Paul's macro's for new/delete etc, but use
osg prefixed versions instead to allow greater flexiblity in handling include
ordering.
Have fixed a couple of new/delete[] problems which existed as a result.
To use the MemoryManager to track memory usage simply add
-DOSG_USE_MEMEORY_TRACKING to the compile line.
Have yet to move the osg from using new to osgNew, will do this next.
easier to specify which modes and attributes have been modified without
the user requiring to know to what value, or to have an equivilant attribute
to pass to the have_applied_attribute method. The original have_applied(mode)
and have_applied(attribute) methods have been renamed have_applied_mode(),
have_applied_attribute() as this was required to prevent the mode and type
values colliding during compile (it was causing a compile error when the method
names were the same.)
not delete the object even if its count goes to 0 or below. This should
only be called in special circumstances, the ReaderWriter::ReadResult
being one of them. This new method has allowed the problem of objects
being multiple referenced on return from readNodeFile() & readImageFile().
much more of the core texture setup code. This largely invloved paramterizing
the applyImmediateMode, which has also been rename applyTexImage to reflect
its functionality better.
include change the CameraManipulators so they work with double for time
instead of float. Also added support for DataType to osg::StateAttribute
and StateSet so that they can be set to either STATIC or DYNAMIC, this
allows the optimizer to know whether that an attribute can be optimized
or not.
in testing new glTextParamters update functionality. I have commented out
the call to attaching of the callback so osgtexture outwardly behaves as
before. The code lies dormant just incase we need to use it for testing
in the future.
mode by using a _texParamtersDirty flag in combination with an
applyTexParamters(State&) method which does the paramters setting in one
tidy bundle. This new implementations replaces the CompileFlags submitted
yesterday.
Simplified NodeCallback by remove osg::NodeCallback::Requirements as they
are no longer needed.
Fixed comments in Drawable.
Put guards around cosf definations so that they are only used under Win32/Mac.
Fixed warning in CullVisitor.
inserted a static transform to do the work of rotating the scene, then
applied a standard osgUtil::Optimizer::FlattenStaticTransformsVisitor
traversal to flatten the transfrom down on to the geometry nodes.
Moved CullVisitor/RenderStage/RenderStageLighting across to managing lights
entirely within RenderStageLighting, and changed the management of modelview
matrices so that RenderLeaf now stores the absolute modelview matrix, rather
than a model matrix as done previously. The later allows RenderLeaf's to do
a glLoadMatrix rather than a glPushMatrix/glMultMatrix/glPopMatrix.
level which appears to cause the code to hang, -O works fine for some strange
reason, I havn't found any direct problems in the code. This may be compiler
bug or a code bug, the bug may go away in later versions of GNUC++, the
problem currently occurs under GCC2.96.
plugin names hanging around despite being deprecated. These definiations
confused the make install/make instclean so it tried to link a non existant
library. Have removed old definitions and everything intalls properly once
more:-)
Change the osg::NodeVisitor::getLocalToWorldMatrix() /
getWorldToLocalMatrix() methods so it do not initilize the matrix being
passed to them, and assume the the users has already initiliazed them
appropriately, such as to take account of camera positions.
coords of the intersection point with the scene rather than the world
coord value for that point. The code now uses
osgUtil::Hit::getWorldIntersectionPoint() method for getting the world coords.
Added support for getWorldIntersectionPoint to Viewer.cpp.
Put and #ifdef around the setting of the default display list visitor so
it nolonger sets in under IRIX. This is a world around to the IR graphics
imbending lighting info into display lists, if the display lists are
created before state is set up it produces lighting artifacts such as
flickering. Remove the the default display list init visitor removes
these problems, display lists are then built on the fly and drawables
a drawn for the first time.
does not flatten drawables which have double references to them, but only
one reference with a static transform on it. This case can't be flattened
but this wasn't picked up. The code now detects the case correctly.
distribution clean from GUI examples, these instead should live in the bazaar.
This can better accomodate the many different types of viewer that users are
developming.
