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.
correct redundent groups but for groups which had a single child it was
was not using replaceChild to rettach the child to its parents. It was using
parent->removeChild(group)...parent->addChild(child); which was allow the child
to be attached in a different place than the original group, this broke LOD code.
Have used removeChild instead which solves the LOD problem.
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.
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.
apply(Billboard& ) method which was apply the accumulated transform to
the billbaord geometry when it should have been applying the matrix without
the transform component.
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.
