I don't know what "quadratic dots" are, but I'd suggest that you try the 
version from R-forge.  It has some bug fixes, but it will still be a few 
days or weeks before it makes it to CRAN.  If you still don't get what 
you want, then please put together a simple example and send it to me, 
explaining what you want, and what you see, and I'll try to fix it if 
it's an rgl problem.
