OpenGL light is being operated on, and also now relies upong the standard
osg::State handling of OpenGL modes to switch on the appropriate lights.
The previous static counter mechansim for the light number was causing a
redundent light to be created when the osg plugin created the first osg::Light
to use a prototype for other osg::Light's to be cloned from in the
.osg plugin execution.
The static count mechanism also prevent the lights modes being controlled
independantly from the setting of the light paramters themselves. This
meant that a light once created was global, and couldn't be turned off
locally via the OSG's support for OpenGL mode enabling/disabling. This
has been overcome with the new implementation, the user has complete
flexiblity of when and where to use the different lights at their
disposal.
Renamed the osg::VisualsSettings to osg::DisplaySettings, and
osgUtil::VisualsRequirementsVisitor to osgUtil::DisplayRequirementsVisitor.
Added support for OSG_SCREEN_HEIGHT into osg::DisplaySettings, and added
a DisplaySettings* to the constructors of osg::SceneView and osg::Camera.
it consistent with the rest of the osg::Matrix naming. Updated OSG
distribution to account for new name.
Added support for the STATIC/DYNAMIC osg::Transform::Type to the .osg
ASCII reader/writer plugin and the flt reader plugin.
Removed the non cost version of osg::Transform::getMatrix() as this could
by pass the dirty mechinism.
the functionality clear given the name. This will break user code unfortunately
so please be away of the following mapping.
osg::Matrix::makeTrans(..)?\026 -> osg::Matrix::makeTranslate(..)
osg::Matrix::makeRot(..)?\026 -> osg::Matrix::makeRotate(..)
osg::Matrix::trans(..)?\026 -> osg::Matrix::translate(..)
osg::Quat::makeRot(..)?\026 -> osg::Quat::makeRotate(..)
Also updated the rest of the OSG distribution to use the new names, and
have removed the old deprecated Matrix methods too.
Updates to the osg::Transform, adding preMult and postMult methods and
deprecating the old preRotate,preTranslate,preScale.
Updated the rest of the OSG so that it nolonger uses the deprecated
osg::Transform nodes.
Renamed osgUtil::SceneView::setGlobalState() to
osgUtil::SceneView::setGlobalStateSet() so that the name reflects its
functionality better. Updated osgGLUT::Viewer etc to cope with new
name change.
apply(Billboard& ) method which was apply the accumulated transform to
the billbaord geometry when it should have been applying the matrix without
the transform component.
per scene view. The user can attach a NodeVisitor to do init for them, or
leave it to the default which is to use the osgUtil::DisplayListVisitor
which compiles all display lists and texture objects. The init traversal
is called automatically by the first call to either app() or cull(), so
should not be called by user code during initialization. This ensures
that a valid graphics context has been established before OpenGL is initialized.
osgUtil::DisplayListVisitor has also been updated to use a bit mask for options, and the addition of
compilation of texture objects (via StateAttribute::compile) has also been
added.
different types of optimization on the scene graph - state optimization,
flattening static transforms, combining LOD's and removing redundent groups.
The new Optimizer replaces the once seperate OptimizerStateVisitor.
should be applied to a node or its child with the new osg::Node::setCullingActive()
flag. A mechanism has been implemented so that if child has its culling disabled
then their parents, all the way up to the root are also have their culling
implicitly disabled.
The osg::CullVisitor has updated to take account of
both the explicit control via setCullingActive and the implicit culling
disabling through children being disabled.
This feature is useful for nodes which don't have a bounding volume to cull
against, earth sky implementations and light sources.
The default osg::Node::_cullingActive is true, i.e. culling is enabled by
default.
updated the ReaderWriterBMP.cpp (mods sent in my Geoff Michel) and
moved the osgUtil::Statistics to osg::Statistics in preperation to adding it
to the the Drawable base class.
Also move osg across to using radians for angular paramters by default.
By defining USE_DEGREES_INTERNALLY you can get the OSG to revert to
the old style degrees. This later feature is deprecated and only meant
for helping comptability in the interim.
added support in osgUtil::OptimizeStateVisitor for removing duplicate
StateSet's from the scene graph, previously only duplicated StateAttributes
we're removed.
