- Hi, all. Yes, I have finals starting tomorrow, but there's one little question
- I just *have* to ask... :-)
-
- Fact: QuickDraw GX is going to use quadratic bezier curves a la TrueType.
-
- However: editing quadratic curves is somewhat painful compared to editing
- PostScript cubic curves, because of the number of extra points required to
- describe similar contours.
-
- So: are we going to see lots of GX programs that <ouch> make us use quadratic
- curves to describe shapes? Or <grin> is there some magic way to display cubic
- curves using quadratics? As far as I know, there's no simple way of doing so.
- Does <gasp> GX provide some way of performing this magic? If not <"display
- ignorance" mode on>, shouldn't it?
-
- I guess what I'm worried about is programs showing up that make editing curves
- harder than it needs to be -- much like the spline curves in MacDraw...
-
- Stressfully yours,
-

- P.S. Personally, I *still* think NuGraph sounds a little cooler than "QuickDraw
- GX"... of course, average users might think it was a charting package...
