I have a multi-threaded C++ app which does 3D rendering with the OpenSceneGraph library. I'm planning to kick off OSG's render loop as a separate thread using boost::threads, passing a data structure containing shared state in to the thread. I'm trying to avoid anything too heavyweight (like mutexes) for synchronization, as the render lo...
I have an application that is built against OpenSceneGraph (2.6.1) and therefore indirectly OpenGL. The application initializes and begins to run, but then I get the following exception "attempt was made to execute an invalid lock sequence" in OpenGL32.dll. When I re-run it, I sometimes get this exception, and sometimes an exception abou...
I need to completely disable texturing in OSG. I tried glDisable(GL_TEXTURE_2D) and also using an osg::stateSet, but some nodes that have textures still render their textures. Is there any way to globally turn off texturing? A bit of background : I need to produce an object coverage map for a scene, that is, knowing what object produced...
Hi, I'm studying Computer Graphics as part of my curriculum at my university. The course focuses on scene modeling, rather than rendering or other aspects of computer graphics. We're learning the math behind it and OpenSceneGraph to actually run something. As part of the HW, and also out of sheer interest, I need to create a 3D model,...
Hello, I have a webcam pointed at a table at a slant and with it I track markers. I have a transformationMatrix in OpenSceneGraph and its translation part contains the relative coordinates from the tracked Object to the Camera. Because the Camera is pointed at a slant, when I move the marker across the table the Y and Z axis is updated, ...
Hi there, For an augmented reality project I want to display a high resolution live camera feed. Then in front of this I want to display a model than can be manipulated (translate, stretch, etc) in real time. I was going to use OpenSceneGraph but realized it will be a lot of work to get the manipulations working. So I would prefer a mo...
My job is to upgrade all of our applications that use OpenSceneGraph (an openGl toolkit) version 0.9.9 to the latest and greatest 2.8. Well quite a few caveats come with this task: 1.) After version .9.9 there was a major overhaul the the core OpenSceneGraph (OSG). Commonly used functions and classes were added and removed. Simply put, ...
Hello everyone, We have a modeling tool which uses OCC, and a 3d editor using OSG. What i want to do is, export the model from the first tool and import into the second tool. I have been searching the web for days, but i can't find a solution. Three things can solve my problem: 1 - An exporter for OCC to export into OSG supported form...
I'm trying to build OpenSceneGraph's pdf plugin on a win32 box. The plugin is using cmake's PKG_CHECK_MODULES macro to find cairo and poppler libraries. I don't know how to install these in such a way as to help it find them though. ...
Hello, this is my 1st question in the site. I need a 3DS model loader for opengl applications. Loader should also be able to load .jpg textures. I tried to use OpenSceneGraph for this purpose but this time I have to also use the whole OpenSceneGraph data structure to render the scene. Is it possible to use OpenSceneGraph only for model l...
Does anyone have experience to fairly compare VTK and OpenSceneGraph? I'm more familiar with VTK, but I'm curious as to whether anyone has tried both extensively. I have both built, 5.6 vtk and 2.9.9 osg, can run the examples... at first glance OSG seems more 'rough', but maybe that's OK. In particular I worry about being able to fidd...
