Yeah, I looked into that idea too some time ago, when I was trying to use
WPF/Silverlight directly to render a point cloud. The technique is called
"billboarding", and it is a horrible way to render points... It bloats your
point budget, and the appearance is really bad at various scales. Using the
GPU's native notion of a point is *much* better.
