"attached you'll find some modifications to Producer, osgGA and
osgProducer to enable Mac OS X support for
+ scrollwheels,
+ mightymouse-srollballs
+ new tracking-pads with scroll feature
+ tablet-support (pressure, proximity and pointertype) (Wacom only tested)
I think there was a bug in the windows-implementation of scroll-wheel
support (wrong order of ScrollingMotion-enum, casting problem) which is
fixed now.
The scrollwheel-code is a bit klunky across platforms, some devices on
OS X can report an absolute delta in pixel-coordinates not only the
direction, so for now there is scrollingMotion (which describes the
direction) and scrolldeltax and scrolldeltay. I decided to leave the
scrollingmotion-stuff to not break old code relying on this."
keyboard and mouse events.
Added osgGA::EventQueue class to support a thread safe event queue and adaption
of keyboard and mouse events.
Removed osgProducer::EventAdapter as GUIEventAdapter replaces it.
Adapted osgProducer and examples to work with the new changes to osgGA.
the names of the operations to be logged for stats purposes, or used when
do searches of the operation list. The keep member variable tells the graphics
thread run loop wether to remove the entry from the list once its been called.
Added osgcamera example that uses osg::GraphicsContext to create the required
window for rendering too, will eventually use osg::CameraNode to replace usage
of osgUtil::SceneView.
Added options into osgprerender for controlling how to do the pre rendering i.e.
--fbo, --pbuffer, --fb --window, and also added the option for controlling the
window size with --width and --height.
Drawables,StateSet, and osgDB::Registry.
Added cleanup_frame() from to osgProducer::OsgCamerGroup to help with proper
clean of OpenGL objects before exit, and modified osgviewer, osghangglider,
osgwindows examples to do the extra frame call to cleanup_frame() before exit.
setClearColor so that it passes on its value to Camera::setClearColor(), and
changed OsgSceneHandler to use the Camera::getClearColor() on each new frame
to ensure that it reflects the settings of the camera correctly.
