Display-view-read text file?and format?
 

What's the purpose of writing a view.vw text file and then read and apply it? How to write one? Is there any syntax for writing a text?
I have seen one example but I don't understand each element?
(38 ((
(view-list (
(view-0 ((a1 b1 c1) (a2 b2 c2) (a3 b3 c3) A B "perspective") #(1. 0. 0. 0. 0. 1. 0. 0. 0. 0. 1. 0. 0. 0. 0. 1.))
)))))

Would you please explain the meaning of each parameter? Thanks!
