Vec4Array is-a std::vector and contains a contiguous block of its base type, such as float. I haven't tested this, but you should be able to just call: osg::Image::setImage( width, height, 1, GL_RGBA8, GL_RGBA, GL_FLOAT, (unsigned char*) &vec4Array[0], NO_DELETE); Hope this helps, Cheers, /ulrich _______________________________________________ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
