[osg-users] How to use Font^ as a variable in a C++ program ?

Hi, I would have a quick question : What do I have to include into a visual C++/CLR project to be able to use Font^ ? I have tried to create a ref class, something like this : Code: [SerializableAttribute] [ComVisibleAttribute(true)] [TypeConverterAttribute(typeof(FontConverter))]

Hi Norbert, I'm missing the OpenSceneGraph context in your question. Could you please give us the context, or use a more appropriate forum (stackexchange maybe?) cheers Sebastian Hi, I would have a quick question : What do I have to include into a visual C++/CLR project to be able to use

Re: [osg-users] [build] Problems with compiling osg3.2 with qt5.2.1 and Cmake2.8.12

Hi Peifu, It seems to me that what you encountered is more like a Qt problem than an OSG one. Qt was not able to find glu32. I guess a walkaround is to set CMAKE_LIBRARY_PATH to the path where glu32.lib is. Just search glu32 on your file system and may have to try a few times, since on Windows the

Re: [osg-users] [osgPlugins] loading .obj file from c++

Hi Sam, The model loads fine on osg-3.3.1 and osg-3.2.0, both 64bit compiled with VS2010. There are missing textures, did you try to load your model without textures? Did you try to use the pre-built osgviewer to load the model? Also what is a bit strange: You have a VS2010 release and your VS

Re: [osg-users] How to use Font^ as a variable in a C++ program ?

I think that what you should use is osgText::Text. There, you can do -setFont(font). font is the name of the font that you want to use. -- Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=59112#59112 ___

[osg-users] Best way balance tree??

Hi, I am developing a car simulator, and our scene is very big (100 km. aprox). What do you think is the best way to balance the osg tree?? LOD?? Thanks! -- Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=59113#59113

Re: [osg-users] Best way balance tree??

osgTerrain and virtual planet builder could be used here. Appart from this, use tiles of predictable size and use a quad-tree structure of PagedLODs to organize them. The question is what your source data is ;-) cheers Sebastian Hi, I am developing a car simulator, and our scene is very big

[osg-users] New scheme for configuring the OSG for building against different versions of the OpenGL/OpenGL ES

Hi All, To address some of issues associated with building the OSG with different OpenGL versions/profiles I've introduced into svn/trunk a new CMake based scheme where you just need to set a single Cmake variable at configure time specifying the target and then have our CMake scripts configure

Re: [osg-users] Best way balance tree??

Thanks Sebastian. What about 'pools'? We have been thinking about having a pool system to manage trees (lamps, cars, etc.). We would render only the objects that are near the player. -- Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=59116#59116

Re: [osg-users] Best way balance tree??

Hi Jaime, my last project was a car simulator for Williams F1. And I want to give you few hints. In theory, quad tree spatial terrain database suits best, and this is output from known terrain tools from Presagis, TerraSim, TrianGraphics - they do this automatically for You. So this is the first

Hi Andor, (I know that this thread is more than 3 months old.) I'd also like to work with the primitive restart functionality. Possibly I will run into the same error. But to check this, I have to enable the restart mode first and set a restart index. Like I claimed in my own thread, called How

Re: [osg-users] New primitive restart mode leaking into other nodes

Hi, About the leaking problem : it is because the GL_PRIMITIVE_RESTART mode has no defaut value in OSG. So if you set anywhere in your scene graph, its value (ON or OFF) will not go back to a default OFF value (which is not set anywhere) It's probably possible to add this default OFF value in
