“view based” (surface, edges, what you see) vs “object based” (what it is, simplified) representation:
Children’s stick figures are an example of “object based” representation. The crooked line is indeed an arm, and not the edge of an arm but the object of an arm.
I haven’t found much yet. John Willats appears to be the authority on this.
“Art and Representation: New Principles
in the Analysis of Pictures” was the start of it.
Oh I love these kinds of things happening on my profile in comments.It’s why I bring up stuff like this – for the random branching in comments. I don’t like ‘sticking to the topic’ unless I must.
I say: JIF about 1/2 of the time but I no longer wrinkle my nose as “gif(t)” as I once did and have been overheard saying “gif” the other half. It’s totally interchangable now and has been for me for a few years.I’d actually forgotten that I had once upon a time been “JIF” in the great debate. I remember the author and the when GIF89a format came out with Compushow and the explaining of the pronounciation and all the newcomers who decided they didn’t like the author’s reasoning but mostly they were justifying their saying it wrong for years.
But, amass large amounts of people saying a thing wrong for a few decades and pronounciations change. mob rule or democracy or bullying? Depends how you stand. I’m generally pacifist but I like accurate history whenever viable.
The tl;dr: y’all are saying it wrong but it doesn’t matter.
“For example, Willats  has carefully detailed the
ways that lines conjoin in T-shaped junctions to depict occlusion, Y-shaped junctions to show corners, and L-shaped junctions to show edges. “
