Question by lalalaaa: film making: What are the third z-axis index vectors?
I’m doing an assignment in my photography class where we’re learning about vectors and I got the whole converging, diverging, cutaways, blah blah blah and I got the z-axis stuff, but I can’t find ANYTHING in my textbook about the “third z-axis index vectors” and why they might be used. Does anyone know what they are and why they’re used?

imagine if you can, a stack of abacus’… (them weird chinese counting frames)… if you honestly dont know, google it…
right the stack is 10 layers high, (10 frames) on each frame (layer) is 100 beads… arranged in rows of 10.. this is a basic grid, for plotting in 3D.. sometimes called a map or overlay or spatial grid… so, i need steps going up the castle in some CGI death fest…
step one, will be 111, 122, 133, (remember each square has a number from 1 to 1000.) using this we can plot things in free space, so, when we shoot, we know where things need to be… in relation to the live screen /and the chromakey background.
