Hi, We have a special installation for users which doesn't have such plugin. Is it possible to have a decent font without it? I need to have a small screen font(about 10 pixels or less) which is readable. Thank you! Cheers, igor -- Read this topic online here:

Hi Tim, I just don't understand why Texture2D isn't sufficient for everything you are doing. glTextureRectangle is deprecated, it was a temporary workaround added to OpenGL, you shouldn't need it at all now that OpenGL fully support non power of two textures. So please just use Texture2D all

Hi Tim. Texture2D and TextureRectangle are wrappers around two distinct types of OpenGL textures, and at a C++ level are both subclassed from osg::Texture, so there is no OpenGL level mapping that makes sense in attempting to convert one to the other, and at the C++ level there isn't any means
