c2ac55a44b Fixed the rotation direction of the POINT_ROT_* modes, this was broken by
earlier fixes to the osg::Matrix.

02ef10fcfa Moved all references to osg::Cloner to osg::CopyOp. 2002-01-29 14:04:06 +00:00
Robert Osfield
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.

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.

9a59cf0fe2 Changed the ordering of applying OpenGL modes and attributes back to the original
modes first then attributes since the it was cause a display bug on some
datesets.  It seems that the modes needs enabling before glMaterial's
take affect, at least on the NVidia drivers under Windows and Linux.
The OpenGL reference guide doesn't mention any dependancy so I'm not
sure what the official line is.  Some other OpenGl attribute and modes
need to be applied in that order according to the blue book, however,
drivers, at least the NVidia drivers seem require the opposite.  This may raise
the spectra of before and after mode applies, but this will require extra
support in osg::State and osg::StateAttribute, and would have to be handled
on a per attribute basis, and possibly different of each platform.  Yuck.

13f06f4f93 Reversed the ordering of setting of OpenGL modes and attributes, so that
attributes are now set first, then modes.  This is keep consistent with
the setting of glColorMaterial and glEnable(GL_COLOR_MATERIAL) as specfied
in OpenGL documentation.

32c79ca554 Added a guard to osg::LOD::evaluate so that it returns -1 if the range
matched does not have a corresponding child to relate to.  This can happen
if a user creates more than n+1 ranges, where n is the number of LOD children.

98c8447ae9 Fixed the osg::Light so that it requires the user to explicitly define which
OpenGL light is being operated on, and also now relies upong the standard
osg::State handling of OpenGL modes to switch on the appropriate lights.

The previous static counter mechansim for the light number was causing a
redundent light to be created when the osg plugin created the first osg::Light
to use a prototype for other osg::Light's to be cloned from in the
.osg plugin execution.

The static count mechanism also prevent the lights modes being controlled
independantly from the setting of the light paramters themselves.  This
meant that a light once created was global, and couldn't be turned off
locally via the OSG's support for OpenGL mode enabling/disabling.  This
has been overcome with the new implementation, the user has complete
flexiblity of when and where to use the different lights at their
disposal.

a2cf39fd74 Changed the default field of Y to 45 degrees, as this is probably a better
default than 30 degrees (what it was temproarily) or the 90 degrees that
it was originally.

786dfea3c8 From John Davis, a little addition to the Windows version of the osg::Timer
constructor such that a static variable is used to force the constructor
to check the number of clock cycles per second once, this means that
multiple timers can now be created with incurring a the 1 second delay
used for timming the clock speed every time the constructor is called.

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.

79c1fb531d Fixed problems with osg::Matrix::makeRot(from,to) and osg::Quat::makeRot(from,to)
so that they both use the same implementation (the Quat code now) and the
code has been corrected to work from and to vectors which directly opposite
to one another.
