to the the Drawable base class.

d5ed4e2305 Added an implemention of basic state sorting to the RenderBin, but have commented
out the sort operation as Peformance benifit is currently negligable, will need
to improve on the sort functor to see real benifits.

4be1324b8c Changed the numeric ordering of StateAttributes Types, as part of an
investigation into state sorting.

2c6e85442b Integrated changes for MacOSX, submitted by Phil Atkin, with small mods by
Robert Osfield to maintain compatability under Linux.

7a7a26c2ea Added include/osg/EarthSky and src/osg/EarthSky to cvs.
Also move osg across to using radians for angular paramters by default.
By defining USE_DEGREES_INTERNALLY you can get the OSG to revert to
the old style degrees. This later feature is deprecated and only meant
for helping comptability in the interim.

430c8606e9 Added osg::EarthSky node to the core osg library, and added support for it into
osgUtil::SceneView, osg::CullVisitor, osgPlugin/osg and updated the hangglide
demo to use the new earth sky node.

fc1fa57275 Added support for osg::StateSet comparison operators and using this new feature
added support in osgUtil::OptimizeStateVisitor for removing duplicate
StateSet's from the scene graph, previously only duplicated StateAttributes
we're removed.

ef3217cfde Interegrated changes to Timer from Neil Salter to fix compilation problems which had been introduced by doing #include's within the osg namespace. 2001-09-30 20:41:20 +00:00

8e2f1bdb72 Modified the Matrix multiple method added by Don so it is safer and added comments explaining why it shouldn't be needed as other more efficient methods should be doing the work for us.
Also added Matrix::ensureRealized() to support the lazy initialization of Matrix, whilest keeping the implementation robust so that external calls to Matrix which get values do so on an initialized matrix.

operator [] to reference matrix elements.

ac2bdbda30 1) new implementation of the osg::Matrix class. Note details below.
2) cleaned up osg::Timer, still in progress.  My intent has been to
     pave the way for support for other OS's.
  3) new osg::FrameStamp class which has a frame number, reference
     time for each frame to be app, culled and drawn.  The FrameStamp
     also can be passed to other machines (i.e. cluster) and the
     FrameStamp can be used with the slaves own app,cull and draw.
     I've also added the beginings of a calander time data to the
     FrameStamp to allow time or day and year to be used in setting
     up position of sun/moon etc. etc.
  4) The osg::State now has contains a pointer to the last applied
     osg::Camera and the current osg::FrameStamp, so that drawables
     can use both pieces of information for creating effects such
     CLOD, earth/sky etc.  The osg::NodeVisitor also now allows you
     to attach a FrameStamp to support syncronization of actions on
     the scene graph.

736e0f73c3 o Added osgUtil::StateOptimizeVisitor which traversing the scene
graph and builds up a map of all StateAttributes and StateSets
    and then removes the duplicates. This promotes state sharing
    throughout the scene graph which inturn can significantly improve
    performance thanks to reduced state changing. Particularily
    effective on datasets where a great deal of duplicated state
exists.
  o Added pure virtual compare(const osg::StateAttribute&)
    method to osg::StateAttribute, and implemented it in all the
    subclasses from StateAttribute. Added <,== & != operator
    on StateAttribute and Matrix to support new StateOptimizeVisitor.
  o Added META_Object, META_Node and META_StateAttribute macros to
    Object, Node and StateAttribute respectively which define the
    standard pure virtual methods such as clone, className
    & isSameKindAs.  Changed all the appropriate header files to
    use these macro's rather define them in each header, these cleans
    up the headers considerably.
  o Corrected the implementation of osg::Light::getType so it correctly
    uses a unique type for each of the OpenGL lights (GL_LIGHT0..
    GL_LIGHT7 relates to osg::StateAttriburte::LIGHT_0..LIGHT_7.
  o Changed the definition of osg::StateStateAttribute::Type to
    is now a unsigned int rather than an enum, and have changed the
    name of the previous Type enum list to be Types.  This makes it
    more consistent with the difination of values found in
StateAttribute
    and also easier to extend with having to cast to an enum.
  o From Pail Fredrikson, updated Maitrx.new implemention which uses
    the same matrix orientation as the original Matrix implemention.

81f553aaee o Updated Metrowerks files for MacOS. They aren't 100% there yet,
but getting there.

  o First cut of osgcluster demo.  Very simple beginings.  Alas
    I only one PC here so I can't test it in its current guise.

  o New support for NodeCallbacks, via AppCallback attached to
    osg::Node's, and a default osgUtil::AppVisitor which calls them on
    each frame.

  o Support for traversal masks in osg::NodeVisitor, osg::Node
    which allows nodes to be switched on or off via a bit mask.

  o Suppport for traversal number (frame number) and reference time
    into osg::NodeVisitor to handle syncronization of app and cull
    traversals.  This also assist clustering as traversal number
    master to slaves.
