the osgGA::AnimationPathManipulator to handle it.
Added a new Drawable::ConstAttributeFunctor and make the accept(PrimitiveFunctor)
be a const method so can disallows modification. Added Drawable::supports(...) methods
for each of the AttributeFunctor, ConstAttributeFunctor and PrimitiveFunctor so
that programs can querry whether it is possible to use functors with that object type.
osg::PositionAttitudeTransform::AnimationPathCallback which us an app callback
which uses an AnimationPath to specify the new positions of the transform.
Added AnimationPath code to osglight to animate the positional light.
Added CullVisitor::setCullingMode() code into SceneView so that SceneView's
CullingMode is now properly passed onto CullVisitor. Note, this work
had been done before, but must has been lost in a merge. Umm...
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.
option to the osgoccluder demo.
First the osgGA classes have been generalised a little to better support
new GUIEventHandler subclasses.
Second osgGLUT has a new option for registering a user defined event handler,
the allows the application to add externally extra options to the osgGLUT viewer.
Third, the osgoccluder demo now works in two modes. The original create
four occluder sides to wrap an loaded model, the second an interactive
mode which allows the users to add occluders to the model by pointing
to points and pressing 'a' to add a point, the 'e' to end the occluder
polygon, polygons must be convex, planer and be defined in an anitclockwise
order. To start the osgoccluder in this mode one simple runs it with the
'-c' option. Run osgoccluder with no parameter to get a list of options.
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.
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.
added prefixes and suffixes to libs and plugins. ALl this to accomodate
cygwin...
Also added INST_SYS_PREFIX and INST_SHARE_PREFIX for installation, as well
as "standardizing" the install locations for the various platforms.
the Make directory is left with four files only :
makedefs
makerules
makedirrules
instrules
These work for all platforms supported so far, which include :
Linux
Irix
Solaris
MacOSX
Cygwin
FreeBSD
memory manager published at flipcode.com. This can be turned on
with the OSG_USE_MEMORY_MANGER option which then uses custom global
new and delete operators as well as provide osgNew and osgDelete macro's
which add ability to log line and file from which calls are made.
Updated osg,osgUtil,osgDB,osgText and osgPlugins/osg to use osgNew/osgDelete,
and fixed memory leaks highlighted by the new memory manager.
include change the CameraManipulators so they work with double for time
instead of float. Also added support for DataType to osg::StateAttribute
and StateSet so that they can be set to either STATIC or DYNAMIC, this
allows the optimizer to know whether that an attribute can be optimized
or not.
coords of the intersection point with the scene rather than the world
coord value for that point. The code now uses
osgUtil::Hit::getWorldIntersectionPoint() method for getting the world coords.
Added support for getWorldIntersectionPoint to Viewer.cpp.
Put and #ifdef around the setting of the default display list visitor so
it nolonger sets in under IRIX. This is a world around to the IR graphics
imbending lighting info into display lists, if the display lists are
created before state is set up it produces lighting artifacts such as
flickering. Remove the the default display list init visitor removes
these problems, display lists are then built on the fly and drawables
a drawn for the first time.
