Check the console if your images get scaled to POT when uploaded to the graphics card. If that's the case, this is the main-cause of your slowdown. Try using TextureRectangles (you'll need absolute tex-coords for that) Try subloading your images: create a placeholder image, attach this placeholder image as texture to your geometry, and copy subsequent tga-frames into this placeholder image and dirty the placeholder image. subloading should be much faster than replacing textures. You can get it even more faster (but difficulter to code): use a second thread which holds a shared context, use a pool of textures which are bound to both contexts and a corresponding pool of images, only one texture is visibly bound to your geometry, so now you can fill in the second thread the other textures with images and swap the textures via an update-callback to show new uploaded frames. I hope you'll get the idea. Or convert your images into a .mov and play it via the quicktime-plugin ;-) hth, Stephan _______________________________________________ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
