Well DD I am not a mathematics phd But all this was so theoretical even before Video existed!!! Was not even thought of in reality To say something is obselete before even being tried out when conditions proved to be possible Is on your part ignorant How can you say something you did not use is obselete Iterated had no use for it which is hey Krammer helped with the video component and this is why TMMi owns VDK 1-1.4 as we are told I would say if you are as intelligent in understanding Theoretical mathematical postulated algorithms as it relates to what get are doing, Then your only response should be I am not sure I have never used it etc. Not hypothesize your obselete term!! Truly unprofessional of you especially taking all te time you did for your bashing rightfully so of the VDK 2.0 code Cheers TB
