Ben and Duncan, Thanks for your helpful suggestions. I"m having some difficulty navigating this really good package using my normal learning techniques. When I do 'help(package = "rgl") it seems only a very small subset of functions available show up. Perusing the rgl.pdf downloaded from CRAN demonstrates the same lack of documentation. There is no vignette. In addition, I have found at least one other package with 3d functions (emdbook::curve3d()).
What is the best resource for learning about all the foo3d() and lower level functionality that rgl and its dependents provide? I saw a book at B&N just last week on openGL. Would that be helpful?
