Indeed there isn't a osg::Image class that does cube maps yet. I have been pondering on this issue for a quite while as this topic does occasionally come up. The way to tackle is to have an osg::CompositeImage/ImageList/ImageArray subclass from osg::Image that provides a list of images that can be assigned to a osg::Texture. One would want to scoop up the needs of the texture array support at the same time. Ideally we'd have an ImageBase class rather than subclassing from Image or refactor Image so it's a base class, and then have concrete implementations subclass from this. It's kinda awkward to undertake such a refactoring now though. A template for an ImageArray class could be the ImageSequence class that already holds a list of images internally. Others are welcome to dive in an add this ImageArray class ;-) Robert. _______________________________________________ osg-users mailing list [email protected] http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
