Hi Ming, What do you mean by the image I set is null? If you want examples of how textures are set up have a look at the OSG examples - just do a search for texture2D. For instance osggeometry has a textured quad. Robert. On Fri, Jul 18, 2008 at 9:43 AM, ka Ming [EMAIL PROTECTED] wrote: Hi,

OSG tries to construct an OpenGL context with stereo properties, but cannot find any type of context that has this type of stereo available. This indicates your Quadbuf stereo is not (correctly) enabled in the NVidia driver. Did you enable the quadbuf in the Nvidia control panel, and do other apps

Hi Ming, The value is null, its 0, its a size, null terminology is used for pointers. It simply means that the texture object hasn't been allocated yet so it doesn't have a size. Only once the OpenGL texture object is compiled by the graphics context will its size be set. Robert. On Fri, Jul
