Hi Tim, Perhaps we could provide an osg::Array subclass for the custom struct that we want, this would give the array scalability and flexibility of matching the C and GLSL structures. Using std140 alignment would be necessary along with users understand the rules of this. This is still better than the current usage is really difficult to understand what is going on.
Relaxing the std140 usage and the knowledge of alignment issues would require some kid of serialization info of the individual parameters. Perhaps one could have a tuple style template class for this that packs the variables into an struct that the template knows enough about to pass the alignment info correctly to/from GL. Thoughts?
