Hi All, I've been looking at the extensions and while I haven't made a final decision my current inclination is to introduce a couple of new classes:
ColorMaski BlendFunci BeldnEquationi These will subclass from ColorMask/BlendFunc/BlendEquation respectively and add an Index parameter that is mapped to the StateAttribute::Member value allow us to individual set each of the appropriate parameters. The glEnablei/glDisablei would also need supporting, for this I'm think that we might need a osg::StateSet::setModei(..) method to complimant the standard setMode() and have osg::State handle the glEnablei/glDisablei depending on whether a particular target is ON/OFF. Thoughts? Robert.
