e1ba8a6292 Added osg::CollectOccludersVisitor which is a helper class for finding active 
occluder in the view frustum, to be used as pre cull traversal.

348419219d Created new helper class osg::CullStack to handle the accumulation of projection, 
modelview and culling sets, to be used during travesal of the scene graph, such
as the cull traversal.

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.

0a8d0a255f More more occlusion culling. 2002-06-08 19:58:05 +00:00
Robert Osfield
bf6bf60e21 Added osgoccluder demo, it creates a single quad occluder, but the culling 
code is not complete yet, so it won't actually do any occlusion culling,
the demo is here so I can test the evolving occlusion culling code.

Robert Osfield
f8502a076c Added support for NodeKits to the osgDB::Registry. Object names in .osg 
files which have the library::class syntax will automatically invoke
the dynamic loading of either a nodekit or database plugin.

09121a1583 Fixed a bug in the Optimizer::RemoveDuplicateNodesVisitor which was prevent 
removal of node which could have been removed.

Added so extra convinience methods to ClippingVolume and utilized them in the
CullVisitor to push and pop only culling planes that are active.

e66372a137 Fixed problem with orhographic projections due to a bug in CullVisitor 
where it automatically resets the near and far to the values calculated
during cull traversal.  The maths for converting the computed far and near
into clip coordinates was wrong, fixed this and the problem goes away.

d140decb44 Added pixelSize method to CullVisitor, and converted small feature 
culling to use the pixelSize method instead of a ratio of radius to
distance from eye point.  setSmallFeatureCullingPixelSize() method
has also been added to provide the user with finer control of small
featyre culling.
