implementations for all the public functions found in the header,
this should prevent problems when not compiling in the MemoryManager
under IRIX 64 build.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
the conclusion that the osg::Matrix::inverse was broken, have lifted a new
implementation from sgl and it seems to work fine. Will need further testing
but looks good.
objects that are deleted whilest still having a positive _refCount, such
as when a object has been deleted on the stack, yet other references still
exist for it. Have put the desctructor implementation in Object.cpp to
avoid adding yet another file with only a couple of lines of code in.
by adding a ComputeTransformCallback to osg::Transform, and have now removed
the recently added AutoTransform since it is nolonger required. Have also
updated CullVisitor to account for the new ways for tracking transformation
matrices in the scene.
on the stack thus ensure that they arn't created locally and have their
memory deleted incorrectly.
Also updated the IntersectVisitor so that it no used osg::ref_ptr<> internally
for storing all data. Have also move the IntersectState helper class to inside the
IntersectVisitor which simplifies the external interface to the class.
class now combines Cloner and DeepCopy into one class. Cloner and DeepCopy
will be removed in next commit.
Also have added osgcopy app to Demos which shows how the CopyOp have be
subclassed to create users own specific handling of copying.
Have fixed copy constructor problems in GeoSet which fix the deep copy
problem experienced yesterday.
copy constructor which takes an optional Cloner object, and the old
osg::Object::clone() has changed so that it now requires a Cloner as paramter.
This is passed on to the copy constructor to help control the shallow vs
deep copying. The old functionality of clone() which was clone of type has
been renamed to cloneType().
Updated all of the OSG to work with these new conventions, implemention all
the required copy constructors etc. A couple of areas will do shallow
copies by design, a couple of other still need to be updated to do either
shallow or deep.
Neither of the shallow or deep copy operations have been tested yet, only
the old functionality of the OSG has been checked so far, such running the
viewer on various demo datasets.
Also fixed a problem in osg::Optimize::RemoveRendundentNodesVisitor which
was not checking that Group didn't have have any attached StateSet's, Callbacks
or UserData. These checks have now been added, which fixes a bug which was
revealled by the new osgscribe demo, this related to removal of group acting
as state decorator.
method
and getWorldToLocalMatrix(), computeLocalToWorld() and computeWorldToLocal()
methods.
Have updated the CullVisitor, IntersectVisitor and Optimizer to use the
new osg::Transform::getLocalToWorldMatrix() which has the same functionality
as the old getMatrix() but is now supports subclasses of osg::Transform
transparently.
Have added osg::PositionAttitudeTransform as subclass of osg::Transform
which manages the transform as position and attitude via a Vec3 and Quat
respectively.
