To set up extension aliases using a config file, an app calls:
osgDB::Registry::instance()->readPluginAliasConfigurationFile(), passing in the file name as the parameter. (Of course this should be done before loading any files whose names depend on the mapping.) osgDB will search for the file using OSG_FILE_PATH.
The file should contain a line for each mapping, with the "map" extension first, followed by a space or tab, then the plugin identifier. For example, a file containing this line:
flt OpenFlight
would map the ".flt" extension to the OpenFlight plugin."
retain objects for several frames before deleting them. Also added RenderStageCache
into CullVistor.cpp that is used for handling RTT osg::Camera's that are being
used in double buffered SceneView usage.
on the screen, it looks more aesthetically pleasing to have a larger
gap between lines than is given by default. I added a new parameter,
lineSpacing, in the Text class to allow the line spacing to be adjustable
by the application. The default value is 0 meaning there is no extra
spacing given. The value should be given as a percentage of the character
height. A good value for longer paragraphs is 0.25 (25%) or more."
copy constructors that take a const osg::CopyOp rather than a
osg::CopyOp&, forcing an unnecessary copy. The attached header fixes
this, based off OSG 1.2.
Also fixed duplicate "or" openArchive()'s comment."
related support into osgViewer::Viewer and osgViewer::StatsHandler.
Added lazy updating of text in StatsHandler HUD to minimize the impact of
slow text updating on observed frame rates.
Added setting of osg_SimulationTime and osg_DeltaSimulationTime to the uniforms set by SceneView
Added frame(double simulationTime) and advance(double simulationTime) parameters to
osgViewer::SimpleViewer, Vewer and CompositeViewer.
Updated various examples and Nodes to use SimulationTime where appropriate.
* Setup proper pixel format for ATI boards (removal of WGL_SWAP_METHOD_ARB specification from the requested pixel format since unsupported by the ATI driver)
* Fix to create sample OpenGL window on the proper display device. This is the temporary window used to choose the desired pixel format. In the previous version, this window was always created on the primary display device, even though it had potentially different pixel formats compared to the target display device containing the window to be created.
* Implementation of WindowingSystemInterface::setScreenResolution() method
* Implementation of WindowingSystemInterface::setScreenRefreshRate() method
* Implementation of GraphicsWindow::requestWarpPointer() method
* Implementation of GraphicsWindow::useCursor() method and associated trait support. This can be used in two ways; first, when the graphics trait requested indicates that no cursor should be present, a new cursor-less window class is used to create the window. When a cursor-enabled window creation is requested, another window class is used. After creation of a window, it is also possible to toggle the cursor state by using the GraphicsWindow::useCursor method.
* The way the mouse behaves is now compatible with the behaviour seen on X11; i.e. when pressing a mouse button, the window where the pointer is located will capture the mouse input and release it only after the button has been released. This results in all mouse movement events being dispatched to the window where the button was pressed initially until it is released. This improves the interaction with graphics windows.
* Preparation work has been done to support the ability of moving a window from one screen to another screen and recreating its rendering context when this happens. This has been tested with a mix of NVIDIA and ATI cards and works properly. For the moment being, this feature is commented out due to changes in the core OSG libraries that have been done but need to be submitted later this week for approval by Robert.
Upcoming features
* Support for moving windows from one screen to another screen seamlessly
* Ability to set the window (i.e. the application itself creates the rendering window and passes it to the GraphicsWindowWin32 class)
* Other miscellaneous items"
---------------------------------------------------
up the StateSetManipulator and moved the initialization of locally cached states
into the handle method to ensure a representative version of the StateSet is captured
Added s/getStats() to osg::View and osg::Camera.
Added population of View::getStats() with frame stats in osgViewer/Viewer.
Added Basic StatsHandler to osgviewer example.
Tweaks by Robert Osfield - Moved methods to FileNameUtils, added unix
implementation of getRealPath add extern and OSGDB_EXPORT to function declarations.
include/osgParticle/ParticleSystem. I replaced
Particle(ptemplate? *ptemplate: _def_ptemp)
with
ptemplate? *ptemplate: _def_ptemp
in a couple of places. This should make particle creation and reuse go
a little faster without all that memory allocation and copying."
+ Multi-display-support
+ automatic hiding of the menubar/dock if one of the windows intersects
the menubar/dock
Bugfixes:
+ event-handling was done by the first opened window, other windows did
not receive events -- fixed
+ mouse-coordinates were absolute, now they are relative to the window.
known bugs:
+ windows with decoration and in fullscreen-size are moved by the system
a little bit, so that the titlebar is accessible/visible. So if you want
real fullscreen-windows, don't decorate the window :)
I updated the XCode-project-file so all ported examples are linked
against osgViewer."
as osg::GraphicsOperation. Unpdated parts of OSG depending upon these.
Added a virtaul bool valid() method to osg::GraphicsContext to allow apps to
test whether a valid graphis context has been created or not.
added frame stamp updating and update traversal to osgViewer::Scene/Viewer.
Updated osgcamera example to use new Viewer API calls instead of using local
rendering calls.
default Registry Options object, but it would be useful to be able to
request loading with a different Options object. The attached files
allow you to do that (based off the OSG 1.2 source).
For example, I'm implementing a loader that requires context information
when it pages in subgraphs, which becomes significantly complicated when
multiple scenegraphs are requesting subgraph loads with different
contexts (the loader needs to know which context to use, and the
Registry Options needs to be carefully managed so the context settings
don't clobber each other, especially in multithreaded situations). Being
able to pass an Options instance along with the Node request resolves
this problem."
Performance tests on big models did not indicate any performance penalty in using doubles over floats,
so the move to doubles should mainly impact precision improvements for whole earth databases.
Also made improvements to osgUtil::PlaneIntersector and osgSim::ElevationSlice classes
2 Getter/setter for _maxNumberOfParticlesToSkip that is used for filtering of particles during draw. This enables you to turn the filtering of by setting this value to zero.
3 Getter for retrieval of the first particle in the trail. This allows you to directly manipulate the trail from your application by walking from the start particle towards the end of the trail."
