5fca8ea229 Moved Drawable across to using osg::buffered_value.
Added new osg::State::setInterleavedArray() method.

Added new osg::Group::setNode(uint,Node*) method.

Cleaned up and fixed the osg::Texture's handling of dirtyTextureParamters().

f867dd81be Added asGroup() and asTransform() methods to osg::Node to downcast nodes
to these types without requiring an expensive dynamic_cast<>.

Also added asGeometry() to osg::Drawable for the same reasons.

12226e4371 Converted the instances of const built in types being returned from methods
and passed as paramters into straight forward non const built in types,
i.e. const bool foogbar(const int) becomes bool foobar(int).

c4c97a0f64 Moved the code referencing osg::BoundingBox::isValid() and
osg::BoundingSphere::isValid() across to use the valid() methods, the later
being more consitent with other classes such as osg::ref_ptr<>.

e1ba8a6292 Added osg::CollectOccludersVisitor which is a helper class for finding active
occluder in the view frustum, to be used as pre cull traversal.

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.

02ef10fcfa Moved all references to osg::Cloner to osg::CopyOp. 2002-01-29 14:04:06 +00:00

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.

54d490e24b Added support for specifying whether view frustum and small feature culling
should be applied to a node or its child with the new osg::Node::setCullingActive()
flag.  A mechanism has been implemented so that if child has its culling disabled
then their parents, all the way up to the root are also have their culling
implicitly disabled.

The osg::CullVisitor has updated to take account of
both the explicit control via setCullingActive and the implicit culling
disabling through children being disabled.

This feature is useful for nodes which don't have a bounding volume to cull
against, earth sky implementations and light sources.

The default osg::Node::_cullingActive is true, i.e. culling is enabled by
default.
