Like OpenGL the OSG doesn't do bounds checking an every call, based on the idea that a properly set up database/application won't need bounds checking everywhere so the overhead associated with such checks would be a unnecessary performance penalty. Since both OpenGL and OSG are performance critical APIs such a policy can make a difference.
