to specific nodes in the scene graph. Typical use would be tagging a
node so that it can't be optimized away in say a flatten static transform
pass. Added methods to Optimizer are:
inline void setPermissableOptionsForObject(const osg::Object* object, unsigned int options)
{
_permissableOptionsMap[object] = options;
}
inline unsigned int getPermissableOptionsForObject(const osg::Object* object) const
{
PermissableOptionsMap::const_iterator itr = _permissableOptionsMap.find(object);
if (itr!=_permissableOptionsMap.end()) return itr->second;
else return 0xffffffff;
}
inline bool isOperationPermissableForObject(const osg::Object* object,unsigned int option) const
{
return (option & getPermissableOptionsForObject(object))!=0;
}
limit the maximum number of occluders used in the cull traversal, default is
now 10.
Added set/getCollectOccluderVisitor() method into SceneView to allow control
of the the settings of the CollectOccluderVisitor.
of iterating through the list of available reader writer, whilst handling
cases where the list itself changes size during iteration through the list.
Previous size changes during iteration was cause invalid iterators, which
in turn was causing a crash.
/** Set the object-space reference radius of the volume enclosed by the PagedLOD.
* Used to detmine the bounding sphere of the PagedLOD in the absense of any children.*/
inline void setRadius(float radius) { _radius = radius; }
/** Get the object-space radius of the volume enclosed by the PagedLOD.*/
inline float getRadius() const { return _radius; }
/** Set the number of children that the PagedLOD must keep around, even if thay are older than their expiry time.*/
inline void setNumChildrenThatCannotBeExpired(unsigned int num) { _numChildrenThatCannotBeExpired = num; }
/** Get the number of children that the PagedLOD must keep around, even if thay are older than their expiry time.*/
unsigned int getNumChildrenThatCannotBeExpired() const { return _numChildrenThatCannotBeExpired; }
instead of osgDB::Registry where it original lay. This has been done to allow
fileName strings to be encode data rather than just file names, such as one
requires when using PagedLOD along with plugins for doing dynamic tesselation.
extra pass to doing tri stripping in the osgUtil::Optimzer.
Added validity checks into osg::TexEnvCombine to catch eronous enumarant values.
Improved the efficient of CullingSet's handling of new transforms.
Added a copy shared subgraphs and subdivision code into osgUtil::Optimizer.
Fixed crash associated with .osg files which contain empty description fields.
From Sondra Inverson, added support to .ive plugin for osgSim::DOFTransform.
saved to .osg properly.
Added osg::ClusterCullingCallback to Drawable header/source. Not complete yet,
but will enable drawables to culled is they are facing away from the eye point.
to and command line arguments to set it.
Added support for using the DisplaySettings::getDisplayType() to detect use
of a Head Mounted Display when doing stereo so that the asymtric frustum can
be switched off.
Generalised the osgDB::Field so that its getFloat() method can be used with either doubles or
floats governed by the type passed in - this helps support either float/double
Quat and Matrix classes seemlessly.
methods to check all atributes and to report warnigns when errors are detected.
Added a CheckGeomtryVisitor to osgUtil::Optimizer to detect eroneous Geometry
before rendering.
the state stack, thus readying the state object to recieve a new frame.
Removed the state.reset() call in osgUtil::SceneView::cull() as this was
causing problems with stats producing inheritance of state when toggling
stats on.
Made Matrix be a typedef to either Matrixf or Matrixd. Defaults to Matrixf.
Converted the osgGA::MatrixManipulators and osgProducer::Viewer/OsgCameraGroup
across to using exclusively Matrixd for internal computations and passing betwen
Manipulators, Producer and SceneView. Note, SceneView still uses Matrix internally
so will depend on what is set as the default in include/osg/Matrix.
Added the ability to osgProducer::setDone/getDone(), kept done() as the
method that the viewer main loop uses for detecting the exit condition.
value to float, and converted the internal code across to use value_type. This
allows Matrix to be converted to use double's simply by change the definition
of value_type. Added Matrix::glLoadlMatrix and Matrix::glMultMatrix() to
help encapsulate the changes between float and double matrix usage.
Updated code that uses Matrix so it doesn't assume float or double matrices.

"Most relevant news:
1) particle systems now have the "freezeOnCull" property set to false by
default. Since it is an optimization, and using it may cause some unwanted
behaviors if not handled properly, it makes more sense to turn it off by
default.
2) new "LINE" shape mode which uses GL_LINES to draw line segments that
point to the direction of motion.
3) particles can now have a rotation angle and angular velocity.
4) new AngularAccelOperator applies angular acceleration to particles.
5) particle processors such as emitters and programs can have a "start",
"end" and "reset" time coordinate. For example, an emitter may be instructed
to start emitting particles only after a certain time, stop after another
amount of time and then start again.
Update (2) is from Gideon May.
Updates (3) to (5) are from Douglas A. Pouk."
part of prep for supporting both Matrixf (float) and Matrixd (double).
Added osg::Matrixf::glLoadMatrix() and osg::Matrixf::glMultiMatrix() methods
and changed corresponding usage of glLoad/MultMatrixf() calls across to use these
methods. Again prep for support Matrixd.
Fixes for VisualStudio 6.0 compile.
made ENABLE_ALL_CULLING enable all culling including the near and far plane.
DEFAULT_CULLING is now used for the default as uses the same original
values as ENABLE_ALL_CULLING once did - view frustum culling with near and
far culling. SceneView now uses DEFAULT_CULLING.
this are replaced by the osg::computeLocalToWorld/WorldToLocal() functions
found in osg/Transform.
Made the ReleaseTextureAndDisplayListsVisitor a public nested class of
osgDB::DatabasePager to allow it to be used in the TXP plugin, and added
usage of this visitor to the TXP plugin to make sure that textures and
display lists are released during the update thread.
Added computeInternalOptimziedGeometry() and associated methods to Geometry
to support alternate versions of a geometry to be used to optimize rendering,
such as flattening indexed attributes to straight attribute arrays.
