6f392cdbfa Ported distribution across to use the new osg::MatrixTransform and osg::BlendFunc
class instead of osg::Transform and osg::Transparancy respectively.

0c943945f7 Implemented most of the changes required for supporting multitexturing in
the osg::State/osg::StateSet/osg::StateAttribute and related classes.

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.

6ed233d0d2 Added DataVariance enum and set/get fields to osg::Object to help identify
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.

84d2d01163 Added support for osg::MemoryManager which is based upon Paul Nettle's
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.

c49c62ee15 Integrated various changes worked on at the Glasgow Science Center. Changes
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.

02ef10fcfa Moved all references to osg::Cloner to osg::CopyOp. 2002-01-29 14:04:06 +00:00
Robert Osfield
2487861fbc Have add new osg::CopyOp which replaces last nights osg::Cloner, the new
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.

f612924a45 Added support for shallow and deep copy of nodes, drawables and state, via a
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.

30db615333 Fixed bug in osg::StateSet::merge(..) where the containers were being
iterated from begin() to begin() rather than begin() to end().

4d4ff39ff9 Added a bool paramter to osg::StateSet::compare(const StateSet& rhs,bool compareAttributeContents=false) const;
to allow it to use different comparison schemes, now it can use checking for pointer equality (the default)
or attribute contexts.  This has been added to assist optimization of databases within the flt loader, but
also could be useful for other operations too.

25c8b05914 Integrated Geoff Michel's updates to Stats code, whilest move all text rendering
back in the viewer from the Statistics header.

Added a osg::State::captureCurrentState(StateSet&) method and a copy constructor
to osg::StateSet.

59077fed15 Added support for automatic creation of global StateAttributes to osg::State,
these global attributes are created by cloning any attributes which are
applied during rendering, the clone in a shallow copy, which will set up
default valus for that attribute.  This should prevent attribute bleed
from one stateset to the next when the global StateSet doesn't contain
an attribute used within the scene graph.

39ea16aad7 Added osg::StateSet::merge(const StateSet& rhs) merges merges the modes and
attributes of rhs into 'this' stateset.

d5bff10797 Changed the ordering of comparing modes and attributes in
osg::StateAttribute::compare() as part of an investigration into state sorting.

fc1fa57275 Added support for osg::StateSet comparison operators and using this new feature
added support in osgUtil::OptimizeStateVisitor for removing duplicate
StateSet's from the scene graph, previously only duplicated StateAttributes
we're removed.

777e4ab9f1 Added setAttributeAndModes(new Depth,StateAttribute::ON);
to the StateSet::setGlobalDefault() so that the correct default for the glDepthFunc etc are set up for scene graphs, and allows override of these value which risk of inheriting state on to the rest of the scene graph.

This has allowed the hangglide demo to be simplified since it now doesn't need to set the global Depth instance itself.
