Hi Thomas, > I'm not sure of what form this method needs to take yet.. will do some > further thinking on the topic.
I have settled upon a new SubloadCallback method: class OSG_EXPORT SubloadCallback : public Referenced { public: virtual bool textureObjectValid(const Texture2D& texture, State& state) const { return texture.textureObjectValid(state); } ... }; And a new Texture2D helper method, Texture2D::textureObjectValid(State&) that can be used by the SubloadCallback as above with the default implementation, or by osg::Texture2D::apply() itself to tell whether any modifications to the Texture2D's Image will mean that the TextureObject needs discarding and a new one to be created. This change is now checked into svn/trunk. Since the default behaviour of the callback and Texture2D is the same as before this won't fix your example, to fix the example one simple adds: virtual bool textureObjectValid(const osg::Texture2D& , osg::State&) const { return true; } To the NPOTResizeCallback. Changes example attached. I haven't rolled this change out to other Texture classes yet as I want the new methods to be tested properly first. Thomas could you test out svn/trunk and let me know how you get on. Cheers, Robert. _______________________________________________ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
