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.

ae5e4f848f Added new osgcallback demo, and updated small API changes to improve the

Added beginings of convex planer occlusions culling.

ae8076f83b dded osg::ClipNode class for managing OpenGL clipping planes, and osgclip demo. 2002-05-02 00:14:40 +00:00

360247225e Added new osg::DrawPixels class with encapsulates glDrawPixels as and
osg::Drawable.  Added osg::Image::readPixels to osg::Image.

Made osg::LightSource to default to cullActive set to false to that LightSource
nodes don't get culled by default.

e0adca775b Reinstated Norman Vine's TARGET_BASENAME variable in the makefiles and
added prefixes and suffixes to libs and plugins.  ALl this to accomodate
cygwin...

Also added INST_SYS_PREFIX and INST_SHARE_PREFIX for installation, as well
as "standardizing" the install locations for the various platforms.

3e6638320a The new order for building OSG. All Makefiles are replaced and
the Make directory is left with four files only :
    makedefs
    makerules
    makedirrules
    instrules

These work for all platforms supported so far, which include :
    Linux
    Irix
    Solaris
    MacOSX
    Cygwin
    FreeBSD

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.

56cee8c711 Move the applying of Projection and ModelView matrices into osg::State so that
it now maintains references to the last applied matrices, automatically doing
lazy state updating.  This simplifies the various places in the OSG which
were previously doing the applying, add paves the way for managing the
projection matrix within the scene graph.

Remove MemoryAdapter and mem_ptr as they arn't being used, and can potentially
confuse users by their existance.

651a22453a Added osg::MemoryManger which is currently based on Paul Nettle's memory manager
published at flipcode.  I havn't adopted Paul's macro's for new/delete etc, but use
osg prefixed versions instead to allow greater flexiblity in handling include
ordering.

Have fixed a couple of new/delete[] problems which existed as a result.

To use the MemoryManager to track memory usage simply add
-DOSG_USE_MEMEORY_TRACKING to the compile line.

Have yet to move the osg from using new to osgNew, will do this next.

e87f7cf853 Updated the makefiles to all have the #!gmake reference to force IRIX
compilation using gmake rather than pmake or smake.  This gets round
issues with exporting OSGHOME.

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.

af968b00bd Added first cut at new AutoTransform node which will be used for generating
Transform's during the cull traversal such as for earth/sky etc.

2487861fbc Have add new osg::CopyOp which replaces last nights osg::Cloner, the new
class now combines Cloner and DeepCopy into one class. Cloner and DeepCopy
will be removed in next commit.

Also have added osgcopy app to Demos which shows how the CopyOp have be
subclassed to create users own specific handling of copying.

Have fixed copy constructor problems in GeoSet which fix the deep copy
problem experienced yesterday.

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.
