Suggestion: How about to use unit square instead of unit quad? about webgl-fundamentals HOT 4 CLOSED

I don't feel like "square" is really accurate because it's not a square unless you manipulate it into one by scaling it with extra math. In other words, if you take a unit quad and draw with gl_Position = position on a default canvas you'll get a 150x75 rectangle which is not a square.

Yes it's not square in pixel space.
But doesn't it square in clip space??

from webgl-fundamentals.

what size is clip space? To me, clip space is some arbitrary size. I think it's confusing to call something that doesn't appear to be a square a square.

I don't think of clip space as a square. I think of clip space as the space of the canvas (or whatever we're rendering to). In that space a 0 to 1 by 0 to 1 quad does not appear to be a square.

But I get it's an opinion. if you want to write "unit square" in Korean that's fine by me but I think I prefer unit quad in English since I feel like I'll get questions why it's not appearing as a square

Ah I understand it.
Actually when I read this sentence:

A unit quad is a quad (square) that's 1 unit big.

I imagine like this:

So I think it's a square.
But as you told, rendering result can make people confused.
I'll translate it into quadrilateral.
