ammendments by Robert Osfield, adding get/setSharedStateManager()
methods into osgDB::Registry, and clean up fixes in SharedStateManager
for the StateSet arrays.
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.
