support for the unsigned int member to be paired with types in osg::StateSet
so that lights, clipplanes and other attributes that have a type group but
then need to differentiate within that group via a member uint.
the state stack, thus readying the state object to recieve a new frame.
Removed the state.reset() call in osgUtil::SceneView::cull() as this was
causing problems with stats producing inheritance of state when toggling
stats on.
by osgUtil::RenderLeaf to test if any abort state has been set, if so it
doesn't do any further drawing.
The osgProducer::Viewer has been set up to set the osg::State's it manages
with their AbortRendering flag pointers set to the osgProducer::Viewer::_done
memeber varaible. Now when escape is pressed the rendering is aborted early.
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.
Added new osg::State::setInterleavedArray() method.
Added new osg::Group::setNode(uint,Node*) method.
Cleaned up and fixed the osg::Texture's handling of dirtyTextureParamters().
code which modifies the OpenGL state and needs to tell the osg::State
about it to ensure that the OSG doesn't make any errors during lazy
state updating.
and a fix to osg::State's secondary color code from Bob Kuehne.
Moved the body of the getGLExtensionFuncPtr() into the header to help out
support for Windows mapping of different OpenGL extensions function ptr per
dll.
Converted AnimationPath so it is now subclassed from osg::Transform::ComputeTransfromCallback()
so that it can be directly attached to the scene to move objects about.
Changed the osg::SateSet::setGlobalDefaults() so that is sets GL_DEPTH_TEST
to ON.
Added guards and creation of default helper classes in osgGLUT::Viewer and
osgUtil::SceneView so that sensible defaults are used when no settings
are used of osg::State/StateSet,osgUtil::RenderStage/RenderGraph/CullVisitor.
in progress for the new support for controlling the projection matrix from
within the scene graph.
Also Added osg::State::getClippingVolume(), getProjectionMatrix() and
getModelViewMatrix() with allows drawables to access the current projection,
and model view matrices and the view frustum in local coords to the drawable.
it now maintains references to the last applied matrices, automatically doing
lazy state updating. This simplifies the various places in the OSG which
were previously doing the applying, add paves the way for managing the
projection matrix within the scene graph.
Remove MemoryAdapter and mem_ptr as they arn't being used, and can potentially
confuse users by their existance.
easier to specify which modes and attributes have been modified without
the user requiring to know to what value, or to have an equivilant attribute
to pass to the have_applied_attribute method. The original have_applied(mode)
and have_applied(attribute) methods have been renamed have_applied_mode(),
have_applied_attribute() as this was required to prevent the mode and type
values colliding during compile (it was causing a compile error when the method
names were the same.)
modes first then attributes since the it was cause a display bug on some
datesets. It seems that the modes needs enabling before glMaterial's
take affect, at least on the NVidia drivers under Windows and Linux.
The OpenGL reference guide doesn't mention any dependancy so I'm not
sure what the official line is. Some other OpenGl attribute and modes
need to be applied in that order according to the blue book, however,
drivers, at least the NVidia drivers seem require the opposite. This may raise
the spectra of before and after mode applies, but this will require extra
support in osg::State and osg::StateAttribute, and would have to be handled
on a per attribute basis, and possibly different of each platform. Yuck.
attributes are now set first, then modes. This is keep consistent with
the setting of glColorMaterial and glEnable(GL_COLOR_MATERIAL) as specfied
in OpenGL documentation.
