OSG Change log
==============
21th September 2001 - osg-20010921.tar.gz
o Fixed compilation problem under Windows due to ctime being included
in the osg::Timer header file. The ctime refrence has been replaced
by time.h. Also fixed typo in osgGLUT/Viewer.cpp which was causing
compilation problems.
o Made the new osg::Matrix::translate/scale/rotate static method inline
to help improve peformance.
o Fixed bugs in osg::Matrix::preMult and postMult.
19th September 2001 - osg-20010919.tar.gz
o Cleaned up the implementation of the osg::Timer class so it is easy
to read and maintain, and have added support for gettimeofday under
unix OS's where no other realtime timer is available, if this isn't
available either than
o Added FrameStamp class which encapsulates the frame number,
reference time and the calander time that a frame in schedualed.
o Fixed a couple of bugs & integrated further fixes from Paul Fredrikson,
to the new Matrix implemention, double checked results against the old
matrix class and am now getting consistent results. For this dev
version onwards the new Matrix class simply replaces the old one. The
new Matrix class contains old style methods to keep things compiling,
however these are deprecated and will be removed, probably by the next
full release. Check the header file for deprecated methods. You can
also comment in the #define WARN_DEPRECATED at the top of Matrix.cpp
and this will produce console warnings.
o From Don Burns - fixes to src/osgPlugins/osg/GeoSet.cpp adding in
an iterator increment to the code for outputing interleaved arrays,
previously the code entered an .osg writing inifite loop for this
data type.
o Have added #ifndef WIN32 around the call to the new OptimizeStateVisitor
which was added to sgv to prevent its use automatically under Windows -
thus avoiding the windows crash due to the MSVC++ buggy SLL implementation.
14th September 2001 - osg-20010914.tar.gz
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.
Even on already optimized datasets such as Performer town up
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.
11th September 2001 - osg-20010911.tar.gz
o From Paul Fredrikson - added new proposed Matrix implemention, its
been added in as Matrix.new and Matrix.cpp.new, the old Matrix
implemetion has been moved to Matrix.old and Matrix.cpp.old, and
new Matrix and Matrix.cpp directs compilation to Matrix.new if
USE_NEW_MATRIX is defined, otherwise defaults to Matrix.old. Once
a new implementation is settled and thoroughly tested then the
old one will be completely replaced by the new one.
o Added osg::NodeVisitor::s/getTraversalNumber(..) and s/getReferenceTime(..)
to better support syncronization of different traversals of the scene
graph and support osgcluster syncornization through the traversal number
and refernce time.
o Added osg::NodeVisitor::s/getTraversalMask(..), s/getNodeMaskOverride(..)
and validNodeMask(..) and modified all osg::Node's and its
subclass' ::accept(NodeVisitor) methods to check NodeVisitor::
validNodeMask(..) and only call the NodeVisitor::apply(..) if it
returns true. This extra functionality allows users to switch on/off
nodes and their subgraph using a Node::s/getNodeMask() and since
a bit mask is used this can be done selectively for different
traversals, by using diffent bits for a traversal type (i.e app/cull).
o Added reuse of AlphaFunc and TexEnv objects between ImpostorSprites
into osg::ImpostorSpriteManager.
o Added osgcluster demo (can be found in src/Demos/osgcluster/), this
demo demonstrates a simple implmentation of keeping camera in sync
between entirely seperate apps running on different machines, and
what you get is multi-channel graphics cluster! osgcluster uses
UDP packets to keep the camera position in sync between other
osgcluster viewers running on other machines in the local area
network.
o Changes to osg::Camera - added osg::Camera::setFOV(), osg::Camera::
s/getAdjustAspectRatioMode(), and osg::Camera::adjustAspectRatio(),
and renamed AdjustAxis enumerate AdjectAspectRatioMode.
o Updates to osg::NodeCallback and osgUtil::AppVisitor.
24th August 2001 - osg-20010824.tar.gz
o Changed the impostor viewport so it is centered in the middle of
main viewport instead of the bottom left hand corner. The later
was causing problems with the windowing decoration was obscuring
the backbuffer drawing and texture read.
o Changed the default resolution to 800x600 for osgGLUT::Viewer and
osg::Viewer so that the demos appear ok on very small screens such
as laptops.
o Three items added for support of app traversal callbacks.
- added osg::NodeCallback for use as an app callback on osg::Node's
which is called by an app visitor.
- added osg::Node::setAppCallback()/getAppCallback().
- added osgUtil::AppVisitor and made it default AppVisitor on SceneView.
note: new files are include/osg/NodeCallback,
include/osgUtil/AppVisitor and src/osgUtil/AppVisitor.cpp.
o Changed osgreflect and osgcube demos so they use an app callback,
instead of its own app visitor/glutTimerCallback repsectively.
o Changed the texture object type from osg::uint to GLunit in osg::Texture
to solved comptability problems under MacOS.
o Fixed spelling mistake of Minimum which occured several times
in include/osgUtil/VisualsRequirementsVisitor.
o Removed Lighting.cpp as it is nolonger used in any Makefiles,
and is only laying around due to not be removed earlier.
o From Bryan Woods - updated Metrowerks files for the MacOS port.
22nd August 2001 - osg-20010822.tar.gz
o Removed osg::StateSet::getAttributeVector() and getModeVector()
since they were simply hacks around MSVC++ bugs which are both
fixed by using STLport under windows, along with other bugs reported
under Windows. Its is now recommended that Windows users adopt
STLport instead of the MSVC++ one since the later is just plain flakey.
o From Ben Discoe - fixed typo of a bookmark in index.html
o Added osg::Viewport for encapsulating glViewport and for passing around
viewport object between various osg classes. Also helps avoid some
portability issues which have arisen over OpenGl types under MacOS.
o From Bryan Woods - updated Metrowerks files for the MacOS port.
9th August 2001 - osg-0.8.42.tar.gz
o Toned down the specular light values set by default in osgUtil::SceneView::
