99f80a78f1 From Ruben, added handling of vertex indices. 
Note from Robert.  New codes produces errors when running
osgfxbrowser cow.osg so I have elected to keep the original
implementation of compute_basis_vectors around and as the default
compile to keep the CVS version working.  Ruben's new version
of compute_basis_vectors has to be explicitly compiled in by
toggling an #if 1 block to #if 0.

        {
            _permissableOptionsMap[object] = options;

            if (itr!=_permissableOptionsMap.end()) return itr->second;
            else return 0xffffffff;
        }

        inline bool isOperationPermissableForObject(const osg::Object* object,unsigned int option) const
        {
            return (option & getPermissableOptionsForObject(object))!=0;

83bf813e58 Moved the responsibility for finding file to load on to the ReaderWriter plugins,

requires when using PagedLOD along with plugins for doing dynamic tesselation.

Robert Osfield
bd44cfcfd8 Added a Matrix::value_type typedef'd trait into osg::Matrix, defaulting its 
value to float, and converted the internal code across to use value_type.  This
allows Matrix to be converted to use double's simply by change the definition
of value_type.  Added Matrix::glLoadlMatrix and Matrix::glMultMatrix() to
help encapsulate the changes between float and double matrix usage.

Updated code that uses Matrix so it doesn't assume float or double matrices.
 2003-09-03 10:47:25 +00:00

and changed corresponding usage of glLoad/MultMatrixf() calls across to use these
methods. Again prep for support Matrixd.

f36bc69c58 Made the more of the OSG's referenced object desctructors protected to ensure 
that they arn't created on the stack inappropriately.

Split the implemention of Matrix up so that it is a simple no referenced counted
class and can be safefly created on the stack.  To support referenced counting a
seperate subclass now exists, this is RefMatrix which inherits from both Matrix and
Object.

Robert Osfield
d91b848a63 Checked in migration from osgUtil based GUIAdapter code to Neil Salter's 
osgGA (Gui Abstraction).  This may break users code, but all it should
require to fix the builds should be a change from
osgUtil::CameraManipulator (etc) to osgGA::CameraManipulator and
include <osgUtil/CameraManipulator (etc) to osgGA/CameraManipulator and
the extra dependency of the link line.

osg::Camrea::getModelViewMatrix() and osg::Camera::getProjectionMatrix() are
calculated on the fly.  Removed various redudent methods, including the
project and unproject methods which are better supported within osgUtil::SceneView.

Added a computeWindowMatrix() method to Viewport, to make it easier to construct
