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.
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.
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.
change in osg::Billboard.
Removed in instance of an object being passed () brackets, have removed the
brackets to avoid an amiguity with the compiler intepreting it as a function.
Alas changed the indenting to use 4 spaces instead of tabs, this irons out
differences when working under Windows and Unix, keeping the identing
consistent.
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.
defined the value to be 2048, this should avoid problems with path lengths
which have been overflowing the 1024 limit (Sasa report this bug). The
real solution is to use std::string throught FileUtils, but this will have
to wait for another day.
from passing the vector contents to the GeoSet::setPrimLengths(..) etc.
methods. This has been done to fix the compile under the MS .NET compiler
which has changed the definiation of the std::vector<..>::iterator to
a class rather than a pointer.
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.
