Moved all #include "osg/.." references to #include <osg/..> to aid port to MacOS. 2001-10-22 05:27:40 +08:00			`#include <osg/Object>`
Initial revision 2001-01-11 00:32:10 +08:00
Added a DeleteHandler into osg::Referenced so that it can delete objects via a seperate delete handler. Useful for making unref()/ref() thread safe if the users needs to address this issue. 2002-12-16 18:25:31 +08:00			`namespace osg`
Added a check to the destructor of Referenced so that it detects referenced objects that are deleted whilest still having a positive _refCount, such as when a object has been deleted on the stack, yet other references still exist for it. Have put the desctructor implementation in Object.cpp to avoid adding yet another file with only a couple of lines of code in. 2002-02-07 09:11:20 +08:00			`{`

Moved get/setUserData from osg::Node into its superclass osg::Object to allow other subclasses to add their own custom data. 2002-07-19 03:41:52 +08:00			`Object::Object(const Object& obj,const CopyOp& copyop):`
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. 2002-04-12 07:20:23 +08:00			`Referenced(),`
