The texture data isn't automatically read-back into the associated image but there are calls in osg::Image that can read the current texture.

Re: [osg-users] Assigning one image to another
I believe the method is this one, but make sure to use it in proper place /** Read the contents of the current bound texture, handling compressed pixelFormats if present. * Create memory for storage if required, reuse existing pixel coords if possible. */ void readImageFromCurrentTexture(unsigned int contextID, bool copyMipMapsIfAvailable, GLenum type = GL_UNSIGNED_BYTE); Nick http://www.linkedin.com/in/tnikolov Sent from Benoni, Gauteng, South Africa On Wed, Aug 26, 2009 at 6:38 PM, Brett Thomas Lee brettle...@hotmail.comwrote: yes I have the same problem you have mentioned.Can you please be more specific about the methods in osg::Image please. -- Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=16755#16755 ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
