fa13d948b5 A little more work on Occlusion culling. 2002-06-11 19:52:55 +00:00
Robert Osfield
247cb3ff7e Checked in Macro Jez's additions to osgText to support .osg IO make it
a fully functioning NodeKit.

Also reimplement notify() to try an prevent a crash which has been caused by
to objects in notify.cpp being initiliazed twice, the second time the auto_ptr
holding the dev/null ofstream was being initilized to 0.

348419219d Created new helper class osg::CullStack to handle the accumulation of projection,
modelview and culling sets, to be used during travesal of the scene graph, such
as the cull traversal.

Robert Osfield
d91b848a63 Checked in migration from osgUtil based GUIAdapter code to Neil Salter's
osgGA (Gui Abstraction).  This may break users code, but all it should
require to fix the builds should be a change from
osgUtil::CameraManipulator (etc) to osgGA::CameraManipulator and
include <osgUtil/CameraManipulator (etc) to osgGA/CameraManipulator and
the extra dependency of the link line.

56dc083330 Added support for compute the near and far planes and then applying to
the current projection matrix into CullVisitor itself.  Similar code to
support this has been moved out of SceneView completely.

Added Matrix:: infront of the definition of the static
osg::Matrix::inverse(Matrix) method which was missing.

Robert Osfield
e17261c45f Changed the osg::Billboard comution so that it get passed in the current
modelview matrix rathan than an identity matrix, this matrix is then modified
locally.

Changed the osg::Matrix set methods so they are inline.

Added a few useful comments to MemoryManager.cpp to help people understand
the assert's better.

f8340f9ef5 Removed the cached matrices from osg::Camera, so that
osg::Camrea::getModelViewMatrix() and osg::Camera::getProjectionMatrix() are
calculated on the fly.  Removed various redudent methods, including the
project and unproject methods which are better supported within osgUtil::SceneView.

Added a computeWindowMatrix() method to Viewport, to make it easier to construct
a MV*P*W matrix for converting local coords into screen coords and visa versa.
Converted SceneView and CullVisitor to use this new method.

Robert Osfield
341ffb2361 Further work on cleaning up SceneView and Camera, in particular moving strereo
support out of Camera and into SceneView. Also enabled the option to set the
projection and modelview matrices directly on SceneView thereby removing the
dependance on osg::Camrea to control the view of the scene.

6f65e86057 Further work on removing Camera references from NewCullVisitor and releted
classes, this work paves the way for making osg::Camera an optional
extra rather than a requirement for rendering.
2002-04-09 16:09:19 +00:00
Robert Osfield
3351306d80 Added new osg::Projection node, and osgUtil::NewCullVisitor which are work
in progress for the new support for controlling the projection matrix from
within the scene graph.

Also Added osg::State::getClippingVolume(), getProjectionMatrix() and
getModelViewMatrix() with allows drawables to access the current projection,
and model view matrices and the view frustum in local coords to the drawable.

Robert Osfield
c49c62ee15 Integrated various changes worked on at the Glasgow Science Center. Changes
include change the CameraManipulators so they work with double for time
instead of float.  Also added support for DataType to osg::StateAttribute
and StateSet so that they can be set to either STATIC or DYNAMIC, this
allows the optimizer to know whether that an attribute can be optimized
or not.
2002-03-14 17:34:08 +00:00

a6aa57a255 Added support for seperate traversal masks for standard, left and right
cull traversals.  This allows one to create seperate rendering for left
and right eyes when doing stereo.

Robert Osfield
386b87d4a0 Cleand up the root Makefile.
Moved CullVisitor/RenderStage/RenderStageLighting across to managing lights
entirely within RenderStageLighting, and changed the management of modelview
matrices so that RenderLeaf now stores the absolute modelview matrix, rather
than a model matrix as done previously. The later allows RenderLeaf's to do
a glLoadMatrix rather than a glPushMatrix/glMultMatrix/glPopMatrix.

d12a726d5b Various investigations into culling errors w.r.t matrix inversion resulted in
the conclusion that the osg::Matrix::inverse was broken, have lifted a new
implementation from sgl and it seems to work fine.  Will need further testing
but looks good.
2002-02-07 01:15:15 +00:00
Robert Osfield
a703130aa0 Have taken a few more steps towards support for view dependant transformations
by adding a ComputeTransformCallback to osg::Transform, and have now removed
the recently added AutoTransform since it is nolonger required.  Have also
updated CullVisitor to account for the new ways for tracking transformation
matrices in the scene.

Robert Osfield
7b370fcb57 Made the LineSegment destructor protected to force users to create segments
on the stack thus ensure that they arn't created locally and have their
memory deleted incorrectly.

Also updated the IntersectVisitor so that it no used osg::ref_ptr<> internally
for storing all data. Have also move the IntersectState helper class to inside the
IntersectVisitor which simplifies the external interface to the class.

02ef10fcfa Moved all references to osg::Cloner to osg::CopyOp. 2002-01-29 14:04:06 +00:00
Robert Osfield
f612924a45 Added support for shallow and deep copy of nodes, drawables and state, via a
copy constructor which takes an optional Cloner object, and the old
osg::Object::clone() has changed so that it now requires a Cloner as paramter.
This is passed on to the copy constructor to help control the shallow vs
deep copying.  The old functionality of clone() which was clone of type has
been renamed to cloneType().

Updated all of the OSG to work with these new conventions, implemention all
the required copy constructors etc.  A couple of areas will do shallow
copies by design, a couple of other still need to be updated to do either
shallow or deep.

Neither of the shallow or deep copy operations have been tested yet, only
the old functionality of the OSG has been checked so far, such running the
viewer on various demo datasets.

Also fixed a problem in osg::Optimize::RemoveRendundentNodesVisitor which
was not checking that Group didn't have have any attached StateSet's, Callbacks
or UserData.  These checks have now been added, which fixes a bug which was
revealled by the new osgscribe demo, this related to removal of group acting
as state decorator.

f16776da22 Fixed FlattenStaticTransformVisitor bug which related to incorrect handling
of objects which were transformed by multiple matrices at one time - this
cannot be handled in the flattening process (since we only have one piece
of geometry to transform).  This visitor now handles this case by disabling
flattening of any objects and transforms associated in this way.

acf256c466 UPdates to CullVisitor so that it keeps in sync with the new method paramter
change in osg::Billboard.

Removed in instance of an object being passed () brackets, have removed the

19c99dc94c Further work on improving stereo support in the OSG.
Renamed the osg::VisualsSettings to osg::DisplaySettings, and
osgUtil::VisualsRequirementsVisitor to osgUtil::DisplayRequirementsVisitor.

Added support for OSG_SCREEN_HEIGHT into osg::DisplaySettings, and added

cb8025d913 Renamed osg::Matric::makeIdent() to osg::Matrix::makeIdentity() to make
it consistent with the rest of the osg::Matrix naming.  Updated OSG
distribution to account for new name.

Added support for the STATIC/DYNAMIC osg::Transform::Type to the .osg
ASCII reader/writer plugin and the flt reader plugin.

Removed the non cost version of osg::Transform::getMatrix() as this could
by pass the dirty mechinism.

a434abafd7 Fixes for IRIX build.
Updates to the osg::Transform, adding preMult and postMult methods and
deprecating the old preRotate,preTranslate,preScale.

Updated the rest of the OSG so that it nolonger uses the deprecated
osg::Transform nodes.

Renamed osgUtil::SceneView::setGlobalState() to
osgUtil::SceneView::setGlobalStateSet() so that the name reflects its
functionality better.  Updated osgGLUT::Viewer etc to cope with new
name change.

25c8b05914 Integrated Geoff Michel's updates to Stats code, whilest move all text rendering
back in the viewer from the Statistics header.

Added a osg::State::captureCurrentState(StateSet&) method and a copy constructor
to osg::StateSet.
2001-10-22 22:02:47 +00:00
Robert Osfield
7082abb8ad Added support for an osgUtil::SceneView::init() traversal which is called once
per scene view.  The user can attach a NodeVisitor to do init for them, or
leave it to the default which is to use the osgUtil::DisplayListVisitor
which compiles all display lists and texture objects.  The init traversal
is called automatically by the first call to either app() or cull(), so
should not be called by user code during initialization. This ensures
that a valid graphics context has been established before OpenGL is initialized.

osgUtil::DisplayListVisitor has also been updated to use a bit mask for options, and the addition of
compilation of texture objects (via StateAttribute::compile) has also been
added.
2001-10-20 20:26:36 +00:00
Robert Osfield
ccc3d3fd8a Added osgUtil::Optimizer which contains four visitor each designed for doing
different types of optimization on the scene graph - state optimization,
flattening static transforms, combining LOD's and removing redundent groups.
The new Optimizer replaces the once seperate OptimizerStateVisitor.
2001-10-19 14:22:02 +00:00
Robert Osfield
3da57d6d22 Added a osg::DegreesToRadians() and osg::RadiansToDegrees() method to osg/Math,
updated the ReaderWriterBMP.cpp (mods sent in my Geoff Michel) and
moved the osgUtil::Statistics to osg::Statistics in preperation to adding it
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.

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.
