Machine Vision. "Stacked Sequence Structure"

[Jokelnice]

Hi.
I have a doubt. Thank you for the cooperation.

Most examples found in the LabVIEW Help that are related to machine vision, used the structure "Stacked Sequence". Is there a technical reason for this to be done in this way?.

Absolutely not.  In some circles, the stacked sequence is frowned upon as an inferior method.

I think they are intended to show you the sequence of operation.  They are also a quick and dirty way of writing functional code.  Not the prettiest, not the best method, but fast and easy and gets the job done.

I would tend toward either a linear sequence with errors wired to maintain order of operation, or a standard state machine architecture for more complex sequencing.

FYI, I am told that many of the LabVIEW examples have been rewritten for the next release.  I am not sure if Vision examples were included in the overhaul.

Thanks.
Precisely for this was that I had my doubts. The courses always suggest minimize the use of these structures ( Flat  and Stacked Sequence structure ) and conversely increase the use of other structures as "state machines" for example. But I worried that the machine vision applications, will use this structure.

You're totally right on this point. Maybe the extensive use of stacked sequence in LabVIEW examples can be realted to the fact that in the past NI employees were not allowed to sit for NI certification exams so they didn't take the rule too seriously  or worse, they had trainnees make the examples 

Anyway I think somewhere on the community there is a place where you can submit examples.

NI, Mysteries.
