Default Explain the difference between rift and quarter sawn, please.

My understanding of quarter sawn wood is that the growth lines run perpendicular to the face of the board. Therefore, it would seem to me that the ideal cut for any quarter sawn board would be radially outward from the center of the log.

However, when I look it up on several websites, it seems like the rift sawing pattern is what would lead to perpendicular growth lines. The quarter sawn pattern they show on several websites only gives you perpendicular growth lines on some cuts in the middle of the quarter. The rest are off 90 degrees. To my way of thinking, based on the cut pattern shown in this example diagram, rift leads to the most 90 degree growth lines (all of them, in fact).

But I've always taken rift to mean somewhere between quarter sawn and flat sawn. Am I missing something?
