Re: [osg-users] Problem using Bones
Hey Dario Do you have any callback or other classes that affect this model or more specifically the bones in any way? One issue might be that somewhere all of the positions of each bone are set to origin. You can always traverse through the bone structure in the model and print out the information. Hard to say without more information. -- Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=62431#62431 ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org

[osg-users] Does osgb support object properties such as visibility in animation?
Hey everyone, As the title says, Im trying to animate the visibility of a model and export to osgb. So far my animation exports have worked fine. I use 3D Studio Max to create an animation on the timeline, export it to .FBX and then convert it to osgb, and split up the animations on the time line while doing so. I recently started changing the visibility under object properties-Rendering Control- visibility on key frames in 3D Studio Max. This change does not seem to follow through when i convert it to osgb though. The animation works fine except for the frames where it is suppose to fade out and then back in. So I am just curious if the osgb file format supports this? -- Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=62432#62432 ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org

Re: [osg-users] FLATTEN_STATIC_TRANSFORMS Not Always Working
I can probably post up the scenegraph, need to double check, but it will have to wait till tomorrow, I left the laptop it's on at home. As for multiple parents, I did check that and everything in the graph has only 1 parent. All I am using the optimizer for is to remove nested groups created for modelling purposes that aren't needed and to collapse the transforms, as they are not needed once modelling is finished as well. Since rebuilding OSG is pain in our current environment, I may just try copying the flatten code from the optimizer in to my own function and do some debugging to try and find out why they are not being collapsed. -Original Message- From: osg-users [mailto:osg-users-boun...@lists.openscenegraph.org] On Behalf Of Robert Osfield Sent: Thursday, January 22, 2015 8:06 AM To: OpenSceneGraph Users Subject: Re: [osg-users] FLATTEN_STATIC_TRANSFORMS Not Always Working Hi Karl, There isn't any way for me to know whether you have hit upon a bug or just that the scene graph you are trying to optimize is structured in way that could can eliminate the transforms as I simply don't have a dataset that reproduces it.

Re: [osg-users] Low frame rate ( Update Callback on 50 bones ).
Hey everyone, I managed to finally sort this out. The bone weights that were displayed in the console as being too small, are I believe only the specific vertexes that had little to no weight. I re exported the .fbx file very carefully making sure the rigging was right and the bones were set up properly. This fixed the distortion issue, so it was a model problem and not the shader program. Much to my happiness :). I also did some deeper analysis of the frames and noticed that my animation models were causing sever delays, when I exported the fbx models to play animations the bone structure accidentally followed along, so for several models that had fairly high poly counts, the skinning was being done on the cpu. I removed the bone structure from my anim models, and now the hands are the only rigged structure on the scene and it makes use of skinning.vert with over 50 fps in debug mode! Thanks to everyone with the patience to help me sort through this. I still don't understand what that 11 as a value for attribIndex means in the init() method of RigTransformHardware, but maybe one day Ill figure that out :). -- Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=62430#62430 ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org

Re: [osg-users] [ANN] [General Purpose Graphical Introspection]
Corrected post with a little more info My basic idea was to use QT wrapping in order to do create and call method object at runtime as cppintrospection … But QML seamed quite promising in order to bring both wrapping and graphical boxing. So I develop some kind of preprecompiler (before moc so I called it pmoc) that read cpp headers and generates customisable QMLplugin code in order to handle: -Nodal logic ( via config file:copy/paste+fx ambiguities leverage) -Pointer life cycle ( via config file: handle smartpointer/normalpointer) -Native object boxing (put native object in QT boxes) -Graphical menu for action ambiguities leverage (when selected and copied type can be used in several action -CPP2QML method wrapping (not finished..I’m doing it by hand for the moment) I tryied to explain a test case applying code generation to OpenSceneraph library on the website but it’s not very technically detailled….(and written in French) http://osg4noob.olympe.in Here's a gross demo http://youtu.be/yAYs5-lYj7k Here's an eldest video showing how to create a particle system https://www.youtube.com/watch?v=mAxGVT_d1bE So the purpose of the underlying tool is not restricted to osg but almost all cpp libraries (without twisted stuff…ex: I have some grammar problems parsing Bullet headers) So Before you tell it “Yes, the interface is ugly” because osg is my testbench and I have lower level things to do like improve the generated code for ex… Here’s an external reference about something near to what i’m doing (https://www.qtdeveloperdays.com/2013/sites/default/files/presentation_pdf/QtDevDaysSFO-2013_WrappingCppForQml_final.pdf) Is anyone know how to raise money for this kind of project?

Re: [osg-users] GL_INVALID_OPERATION at GLBufferObject::compileBuffer()
Hi Anton, Vertex buffer objects are meant to be allocated up to the maximum size you need and thereafter there will be no changes in size. It sounds like you want it to start of zero and expand as required, which rather breaks the how the buffer is meant to work on the OpenGL side and what the OSG is built for. When doing particle systems using shaders and VBO's the way to manage it is to have a fixed sized vertex array and change the number of vertices accessed by changing the size of the primitive sets that tell OpenGL how to access it. There are really too many unknowns to guess what you are planning with your implementation, but for starters I'd start with allocating a vertex array with the maximum size you need. Robert. On 21 January 2015 at 14:03, Anton Semenov allcrea...@gmail.com wrote: Hi, There is an object of osg::Geometry class with enabled hint use vertex buffer and empty(by default) vertex buffers ( it can be something like particle system so vertex buffer will be changed dynamically). When something (GLObjectsVisitor, or Geometry's draw implementation method) calls GLBufferObject::compileBuffer(), we will get undocumented OpenGL error (GL_INVALID_OPERATION) throwed by glBufferSubData call. As I understand, new buffer have both _allocatedSize and _profile._size equals to 0, so branch if (_allocatedSize != _profile._size) can not be executed and vertex buffer leaves uninitialized. It seems this behavior is not dangerous and could not interfere to another nodes rendering, but it causes error messages which can slow program execution. I do not think that problem is serious, but I'm not sure is it planned behavior or bug. Thank you!

Re: [osg-users] [ANN] osgVegetation - A vegetation database builder
Hi Guys, kingarthur10: by looking at the cmake-log I assume that your platform is Linux, unfortunately the library is only tested under Windows (compiled with MSVC2010) but it’s on the roadmap to fix the cmake-files to support Linux builds as well. If you know some cmake I would point you to start looking into the OSGDep.cmake file in the CMakeModules folder, for instance the OSG_BIN_FILES_DEBUG/ OSG_BIN_FILES_RELEASE variables should probably be empty for Linux builds (you usually keep your shared libraries in the path at one location). kornerr: Yes I'll try to upload some screenshots to github tonight, the sample media is however not that impressive so it’s on my todo-list to get some better showcase art.

I couldn't understand it. 2015-01-22 18:56 GMT+07:00 Julien Valentin julienvalenti...@gmail.com: Corrected post with a little more info My basic idea was to use QT wrapping in order to do create and call method object at runtime as cppintrospection … But QML seamed quite promising in order to bring both wrapping and graphical boxing. So I develop some kind of preprecompiler (before moc so I called it pmoc) that read cpp headers and generates customisable QMLplugin code in order to handle: -Nodal logic ( via config file:copy/paste+fx ambiguities leverage) -Pointer life cycle ( via config file: handle smartpointer/normalpointer) -Native object boxing (put native object in QT boxes) -Graphical menu for action ambiguities leverage (when selected and copied type can be used in several action -CPP2QML method wrapping (not finished..I’m doing it by hand for the moment) I tryied to explain a test case applying code generation to OpenSceneraph library on the website but it’s not very technically detailled….(and written in French) http://osg4noob.olympe.in Here's a gross demo http://youtu.be/yAYs5-lYj7k Here's an eldest video showing how to create a particle system https://www.youtube.com/watch?v=mAxGVT_d1bE So the purpose of the underlying tool is not restricted to osg but almost all cpp libraries (without twisted stuff…ex: I have some grammar problems parsing Bullet headers) So Before you tell it “Yes, the interface is ugly” because osg is my testbench and I have lower level things to do like improve the generated code for ex… Here’s an external reference about something near to what i’m doing ( https://www.qtdeveloperdays.com/2013/sites/default/files/presentation_pdf/QtDevDaysSFO-2013_WrappingCppForQml_final.pdf ) Is anyone know how to raise money for this kind of project?

Re: [osg-users] [ANN] [General Purpose Graphical Introspection]
It would be nice to see some explanation video with real world examples of yours. 2015-01-23 6:17 GMT+07:00 Julien Valentin julienvalenti...@gmail.com: I'll try to stay simple: pmoc generate customisable and extendable graphical components embedding objects method and I use in a generic Editor to demonstrate the ability to do runtime graphical programmation: The paste feature introspects the selected object and calls the method that can be used with copied object as a parameter. If several methods fit the couple (class of selected /class of copied) then a menu popup in order to ask you which you want to call. So It avoids programmation and compilation steps as all is done at runtime. More globally (and from my point of view), it allows to highlight features (and so on bugs) of C++ heterogenous (or not in the case of my osg experiment) libraries and allows to mix them in a generalized graphical context to manipulate them. Personnally, I use osg4noob to introspect my own classes when i'm not sure of what I'm doing(where to put what) or when my scene is becoming too complex (ex:it allows to know which PagedLOD are in RAM). It saves me a lot of coding time and so I thought the underlying pmoc was an interesting project to developp deeper. kornerr wrote: So what problems does your software solve exactly?

[osg-users] [Qt] Create a HUD (by using QGraphicsView / QGraphicsScene )
Hi, I work on a project using OSG (with OSG Earth). I create HMI with Qt and add OSG (Earth) view using osgQt::GLWidget devived class (osgEarth::QtGui::ViewerWidget ) and it's work fine. My application needs a HUD over the OSG widget but when I display QWdiget over the GLWidget, it has a black background (only when it is over the GLWidget). It's look like Qt can do transparency when OSG widget is behind. There is a solution for this ? On the net, I found information about QGraphicsView and QGraphicsScene to make a HUD but when I try to use it, ma application crash to runtime with a lot of OpenGl error. My code looks like : Code: _viewerWidget = new GLWidget(viewer); _viewerWidget-setAutoFillBackground(true);; _views.clear(); _viewerWidget-getViews( _views ); _viewerWidget-makeCurrent(); QGraphicsView* view = new QGraphicsView(); view-setViewport(_viewerWidget); view-setViewportUpdateMode(QGraphicsView::FullViewportUpdate); QGraphicsScene* scene = new QGraphicsScene(); scene-addWidget(new LeftPanel()); view-setScene(scene); // Add to MainWindow _ui.widgetForOsg-layout()-addWidget(view); I have a look to osgQtWidgets example but I don't found how to use correctly QGraphicsView and QGraphicsScene. Can you help me please ? Thank you!

I request full files as it's more reliable than applying diff's and avoids any potential copy and paste mistakes at either end. When I do my merges I use a graphical diff so I can see the changes properly in context - without this you can't really make a proper assessment of the fix. I I try to use patch files I'd need to apply the patch files, hope that they merge correctly (but don't have a full proof way of confirming this) and then do the graphical diff against a second check out of the repository.
