239068f223 Added new osg::TextureBase, osg::Texture1D, osg::Texture2D, and osg::Texture3D 
classes, and changed osg::Texture and osg::TextureCubeMap so that they now derive
from osg::TextureBase.

b23a48a763 Renamed the osg::EarthSky to osg::ClearNode to make it more obvious what 
role it has play and make it more relevant to non vis-sim applications.

8036901ea1 Rewrote osg:Statistics so that it is PrimitiveFunctor as is now completely 
decoupled from osg::Drawable.  The Drawable::getStats() virtual method
no longer exists.

Updated the Viewer to use the osg::Statistics incarnation and reformated stats
to clean it up.

8a14aa29cd Added support to osgUtil::Tesselator to insert extra vertices and other 
attributes into an osg::Geometry node.  Uses the new osg::ArrayVisitor.

3700e7e2cd Reimplemted the osgUtil::SceneView::setCalcNearFar() functionality to bring 
it inline with the CullStack/CullVisitor implementation.  Also added the
setSmallFeatureCullingPixelSize() method and wired them up inside
SceneView.cpp so they set the corresponding CullVisitor paramters.

Intergrated pfImage copying change in the Performer plugin, submission sent in by Ulrich Hertlein

d2aa4270ce Added support for CullVisitor to contain a osg::State. This used when 
cull Callbacks require the contextID for  doing operations on texture
objects, for example.  Modified CullVisitor SceneView and Drawable

48e7679e78 Rewrote the osgUtil::Tesselator so that it is easier to use, and can also 
easily retesselate osg::Primitive::POLYGONS found in Geometry objects.
Added calls to the tesselate to the lwo and flt loaders.

40fefcf335 Ported various demos and support classes over to use the new osg::Geometry class 
thus removing dependancy on osg::Geoset from most of the OSG, only loaders
left to port now.

cbeeeefdab Added osg::Drawable::PrimitiveFunctor and TriangleFunctor subclass for 
querrying the primitive data inside Drawables.  Moved various support
classes over from being osg::GeoSet based to osg::Geometry based.

fa13d948b5 A little more work on Occlusion culling. 2002-06-11 19:52:55 +00:00
Robert Osfield
247cb3ff7e Checked in Macro Jez's additions to osgText to support .osg IO make it 
a fully functioning NodeKit.

Also reimplement notify() to try an prevent a crash which has been caused by
to objects in notify.cpp being initiliazed twice, the second time the auto_ptr
holding the dev/null ofstream was being initilized to 0.

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.

99580f2212 Addd libraryName() method to osg::Object in preperation for the osgDB support 
for node kits plugins.

5feba17410 Added new osg::OccluderNode which subclasses from osg::Group, and will 
provide hooks for adding ConvexPlanerOccluders to the scene.

Robert Osfield
553db68bc4 Added osgUtil::CullVisitor::getCurentRenderGraph() and getRootRenderGraph() 
methods which replace getRenderGraph(). Small changing of order of push/pop
of StateSet's in SceneView to clean things up.

00f91631c2 Various API updates to suppor light points developments better, but should also 
benifit other extensions to rendering.

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.

f0e7e8e48b Removed CullViewState from the distribution, moved CullViewState::CullingMode 
into CullVisitor, and then removed all references to CullViewState from other
parts of the scene graph.

8b30a10375 Added code in hangglide to move the earth sky around with the eye point, 
use osg::Transform::ComputeTransformCallback.

Robert Osfield
56dc083330 Added support for compute the near and far planes and then applying to 
the current projection matrix into CullVisitor itself.  Similar code to
support this has been moved out of SceneView completely.

Added Matrix:: infront of the definition of the static
osg::Matrix::inverse(Matrix) method which was missing.
 2002-04-22 14:54:39 +00:00

e17261c45f Changed the osg::Billboard comution so that it get passed in the current 
modelview matrix rathan than an identity matrix, this matrix is then modified
locally.

Changed the osg::Matrix set methods so they are inline.

Added a few useful comments to MemoryManager.cpp to help people understand
the assert's better.

areas.

f8340f9ef5 Removed the cached matrices from osg::Camera, so that 
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
a MV*P*W matrix for converting local coords into screen coords and visa versa.
Converted SceneView and CullVisitor to use this new method.

341ffb2361 Further work on cleaning up SceneView and Camera, in particular moving strereo 
support out of Camera and into SceneView. Also enabled the option to set the
projection and modelview matrices directly on SceneView thereby removing the
dependance on osg::Camrea to control the view of the scene.
