f3d74525fa Rewrote the apply_imp template method so that it takes an initialization
paramater.

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

Converted the osg plugin Geometry support to use the new UByte4 class.

9c56a57de3 Fixed the orientation of the osgreflect demo so that the reflection plane
is orientated towards the viewer.

Changed the lightmodel ambient level to 0.1,0.1,0.1 instead of 0.0, so that
a small amount of ambient lighting is available to render back surfaces.
The osgreflect and osgprerender suffered unexpected behaviors because of
no lighting on the backfaces.

6f392cdbfa Ported distribution across to use the new osg::MatrixTransform and osg::BlendFunc
class instead of osg::Transform and osg::Transparancy respectively.

00470acb61 Fix, sent in by Macro Jez, to the set of the camera with the computed near and far plane, so that
it is only updated when  _computeNearFar != CullVisitor::DO_NOT_COMPUTE_NEAR_FAR.

c4c97a0f64 Moved the code referencing osg::BoundingBox::isValid() and
osg::BoundingSphere::isValid() across to use the valid() methods, the later
being more consitent with other classes such as osg::ref_ptr<>.

0c943945f7 Implemented most of the changes required for supporting multitexturing in
the osg::State/osg::StateSet/osg::StateAttribute and related classes.

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.

21beb236d2 Added support for occlusion of holes in occluders, and cleaned up the
interface to ShadowVolumeOccluders.

b3c26d5634 Changed the osg::LightSource so its Light attribute is now generalised to
be a StateAttribute.  This allows alternative implementations of Lights
other than the standard osg::Light.

5e85cd59ab Added support for occluders occluding other occluders, which helps reduce
the number of occluder that will be used in cull traversal to only the
ones that will be effective. Note. Holes in occluders arn't handled in
this occluder occlusion test, will implement this later.

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.

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

Robert Osfield
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.

165cc1bf42 Changed the method of expanding of the near and far planes in
CullVisitor::popProjectionMatrix so that it better handled models of zero
thickness orthogonal to the viewing direction.

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.
2002-05-23 15:35:12 +00:00
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.

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.

Robert Osfield
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.
