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.
distribution clean from GUI examples, these instead should live in the bazaar.
This can better accomodate the many different types of viewer that users are
developming.
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.
objects that are deleted whilest still having a positive _refCount, such
as when a object has been deleted on the stack, yet other references still
exist for it. Have put the desctructor implementation in Object.cpp to
avoid adding yet another file with only a couple of lines of code in.
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.
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.
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.
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.
method
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.
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.
