Re: [osg-users] CMake build target INSTALL

Ok, the problem seems that Cmake detects a Coin3D 2.4.5 installation only halfway correctly. It is missing the libs and thus I suppose the values from the cache don't make it into the target for the .iv plugin (include directory etc pp). When running the INSTALL target the cmake script craps o

Hi there, two things as of SVN rev 7366 using the INSTALL target in combination with Visual Studio 2003: - osgdb_freetype is not being copied (anyway the plugins folder is not as crowded, I have a hunch that more is missing) - applications like osgversion etc are not copied I did clean cache

Hi Everyone, I'm trying to control transparency of a subgraph from a high level, and I though BlendFunc with BlendColor would be a good way to go. Setting up the two with constant color = (1, 1, 1, opacity_scale) and BlendFunc = (GL_CONSTANT_ALPHA, GL_ONE_MINUS_CONSTANT_ALPHA) allows me to

I need to get a large screen shot (preferably 2352x1796) of my scene. I followed the basic screengrab code: osg::ref_ptr image = new osg::Image; image->readPixels(x,y,width,height, GL_RGB,GL_UNSIGNED_BYTE); osgDB::writeImageFile(*image,_filename); But it didn't work like I wanted it to. By pas

Hello, I don't know anything about the data you want to visualize, but in case of isosurfaces of a scalar field you could get correct sorting via GPU Raycasting (a.k.a. volume rendering) if you manage to fit the scalar field into a 3D Texture on the graphics card. Regards, Joachim Michele Bo

Current svn doesnt build due to that osgIntrospection is missing a reference to osgGetVersion() defined in osg.lib. Either something has changed in osgIntrospection causing this, or a setting in the CMakeLists.txt has disappeared. Therefore the CMakeLists.txt for osgIntrospection should have the
