6ed233d0d2 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.

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.

OSG has to maintian.

b2e2a971fd Updates to Transform and CullVistor to support new getLocalToWorldMatrix methods. 2002-02-12 08:23:07 +00:00

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.

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.

c1283c23e8 Removed the trailing ; after namespace {...} declariations in headers
which was being picked as a warning under Codewarrior.

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.

06bd9fda5b Have made osg::Transform more extensible via additions of new getLocalToWorldMatrix()
and getWorldToLocalMatrix(), computeLocalToWorld() and computeWorldToLocal()
methods.

Have updated the CullVisitor, IntersectVisitor and Optimizer to use the
new osg::Transform::getLocalToWorldMatrix() which has the same functionality
as the old getMatrix() but is now supports subclasses of osg::Transform
transparently.

Have added osg::PositionAttitudeTransform as subclass of osg::Transform
which manages the transform as position and attitude via a Vec3 and Quat
respectively.

625e8e730a Added comment to osg::Transform w.r.t use of GL_NORMALIZE when using
scaling Transforms.

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.

f848c54ba3 Made the following name changes to Matrix and Quat to clean them up and make
the functionality clear given the name.  This will break user code unfortunately
so please be away of the following mapping.

  osg::Matrix::makeTrans(..)?\026 -> osg::Matrix::makeTranslate(..)
  osg::Matrix::makeRot(..)?\026   -> osg::Matrix::makeRotate(..)
  osg::Matrix::trans(..)?\026     -> osg::Matrix::translate(..)

  osg::Quat::makeRot(..)?\026     -> osg::Quat::makeRotate(..)

Also updated the rest of the OSG distribution to use the new names, and
have removed the old deprecated Matrix methods too.

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.

96085619ee Added support for DYNAMIC/STATIC osg::Transform types and added new osg::Drawable::getStats
and supportsAttributeUpdate(..) and applyAttributeUpdate(...) methods which will
be to enable hooks into Drawable subclasses.

9917b6500d Added a copyright notice to all core headers, which all begin with
//C++ header to help scripts and editors pick up the fact that the
file is a header file.
