7e012ccfc4 Renamed PermissableOptions to setPermissableOptimizations. 2003-12-11 23:33:27 +00:00
Robert Osfield
1881610a35 Added support for controlling what optimization operations can be applied 
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;
        }

5295d68fd3 Added _maximumNumberOfActiveOccluders variable to CollectOccludersVisitor(), to 
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.

83bf813e58 Moved the responsibility for finding file to load on to the ReaderWriter plugins, 
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.
