Re: [osg-users] file extension alias
I think there is no need to do any work in the plugins. Registry::createLibraryNameForExtension(const std::string ext) gives you the name of the library (plugin) you have to load having in mind all the aliases.

Re: [osg-users] osgText::Text Drawing order
Hi Andre, Text by default will drop into the transparent bin so this is likely the reason why it's ordering is not exactly what you expect it. Text has to be in the transparent bin to ensure correct blending. Also I don't of if you are aware but rendering order only controls which item depends upon the current setting of the depth buffer - i.e. is depth test on, and what is rejected (normally more distance fragements are discarded) and the depth of the object. If you switch off depth test or the fragments have the same depth and fragements of the same depth pass the depth test will rendering order make a difference. In you case you don't specify what you are doing with the depth test or depth buffer, it's also difficult to guess at what level of understanding you have about depth buffers and depth test. Robert.

I should add: ... or that have the extension in their supportsExtension list. No this isn't a correct understanding. The file extension alias for for plugins that handle a wider range of file extensions that just the extension component of the name of the plugin, or for where the file extension doesn't match the name of the plugin, the quicktime time is a case in point. Hm, I'm afraid I don't quite understand. Isn't the following the case? - plugin X will automatically be associated with extension 'X'. - to support more extensions the plugin must say that it supports 'Y' *and* the Registry must map extension 'Y' to 'X', because otherwise plugin 'X' won't be considered/loaded for extension 'Y'. (I'm not trying to argue what should be done to have an application tell a plugin to handle another extension, or if that's even a case that needs to be supported.) Cheers, /ulrich PS: The Qt plugin might be a bad example because in addition to supportsExtension() in the ctor it explicitly checks the extensions in accepts*Extension(), so to support a new extension one would need to add this in three places. PPS: And it *also* calls addFileExtensionAlias() from the ctor. ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org

Re: [osg-users] file extension alias
Ulrich Hertlein wrote: What extension/plugin did you use it with? I've used this with proprietary plugins that support multiple different extensions for the same file type. As I understand it 'addFileExtensionAlias' really only works with plugins that don't check the extension name. I only register aliases that the plugin supports. The plugin still checks the extension. I think most all plugins check the extension. The osgDB::Registry constructor does the same thing. Consider the QuickTime plugin, the RGB plugin, etc. On a related note, I also have a proprietary plugin that supports possibly dozens of different file types. The actual formats supported are determined by a third party library loaded by the plugin, so there's no way to know what is supported before loading the plugin, and therefore no way to register any aliases. In this case, the client app simply does an explicit load on the plugin library at init time. Once loaded, the plugin is invoked for every read/write regardless of extension, so the plugin itself determines which files it supports whenever a read/write is invoked, by interacting with its third party library. -Paul ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org

Hi Massimo, Sorry, my first reply went to you directly...

Yes, the enums were changed to const members to fit better with the C++ style but I didn't change the code on the front page :-( Try to use osg.StateAttribute.ON instead (without the .Values)... See http://code.google.com/p/osgboostpython/source/browse/trunk/osgBoostPython/lib/osg/__init__.py I've updated the front page now. Sorry about that. ... tring to build osgboostpython http://code.google.com/p/osgboostpython/ , seems that it don't recognize the .dylb files so i had to simlink *.dylb to *.so.

If you have depth test on then you will be using the depth buffer even with 2D projections.. as 2D projections are really no different rather 3D projections in OpenGL, everything in reality is 3D, everything has depth even it's flat and depth value of 0, and if depth test is on then each fragment will be tested against the depth buffer. For a simple OpenGL program I just draw components in sequence.

[osg-users] Question regarding Culling issue in the SceneView
Greetings All,
I added a CullCallback to the camera of a view. I found it was not
getting hit. After much searching I believe it is due to the
implementation in the SceneView:
Specifically at line 957:
// traverse the scene graph to generate the rendergraph.
for(unsigned int childNo=0;
childNo_camera-getNumChildren();
++childNo)
{
_camera-getChild(childNo)-accept(*cullVisitor);
}
Is there a reason that it is simply not replace that whole section of
code with the following?
_camera-accept(*cullVisitor);
Shouldn't the main camera be culled?
I'm somewhat inclined to think so.
I'd appreciate any feedback on why this may not be the case.
-Regards,
Colin Branch

That's interesting. CullVisitor::apply(Camera) is the place where the
RenderStage for the Camera is created/inserted into the render graph, so
I'm not sure how that works if the SceneView is explicitly skipping the
top level Camera. Maybe Robert can elaborate. Perhaps the Renderer does
this automatically (for osgViewer based apps).

Re: [osg-users] Question regarding Culling issue in the SceneView
Hi Colin,
As Paul suggests CullVisitor::apply(osg::Camera) handles in scene
graph camera's, so will not handle the viewer level scene graph
correctly so _camera-accept(*cullVisitor) won't behave correctly.
Perhaps you could try replacing the for loop with
_camera-traverse(*cullVisitor) as this will call the cull callback
and avoid the CullVisitor::applyOsg::Camera) method. If this works
fine let me know as I can make this change to SceneView.cpp.
Robert.

The effect of this is that update callbacks on cameras are not called, and more importantly, update callbacks on nodes that are children of the camera but not part of the view's SceneData will not be called either. We frequently add nodes directly under a camera (instead of under a scene root that's the scene data of a given view) so that the nodes are only visible to that camera. But with the present behavior, update callbacks on those nodes are never called. If, instead of passing the update visitor to the scene data's root, we passed it to the camera's children, then we're sure all visible nodes would be visited, even those in the scene data...

[osg-users] [vpb] What can I do with an ive file?
Hi OSGers, So I just got done creating the Pugent Sound example given from the vpb website. The coloring didn't turn out right, but the elevation map worked. (only the bottom left hand corner is colored with the texture). Now I am left with the .ive file that has a great looking 3D terrain. What i would like to do is to apply my own textures on the 3D terrain on the fly. The texturing would look similar to this: envision.bioe.orst.edu/StudyAreas/Bainbridge/bainbridgeContextMap.jpg I have access to the data represented by map, so I'm assuming I will just need to rasterize it to a texture and then apply it to the terrain. Can I quickly do this interactively(ie not waiting 3hr for it to process)? I would need to use different textures on the fly as the data can change based on the user's input. Also, later requirements request for me to add more detail to the terrain ( such as forests, neighborhoods, cities, water, etc), they want the landscape to be photo-realistic. I would assume instead of painting on colors, I would instead paint forests, neighborhoods, rivers, etc.. FYI, I am a complete newbie to OSG(first post!) and hopefully I have not bitten off more than I can chew :?. Is what I'm trying to do feasible( well I'm sure it is, but is it realisticly doable?)

const long size = width*height*length;
unsigned short* data = (unsigned short*)calloc(size, sizeof(unsigned short));
for(long i=0; i size ; i+= 3)
{
data[i]=255;//red
data[i+1]=0;//green
data[i+2]=0;//blue

// declaration and allocation of the 3d image (size : 100,100,100)
osg::ref_ptrosg::Image image = new osg::Image;
