2) Each "chapter" is quite brief, but also robust. It has some math but also has psuedocode. I would like more code rather than math, but that's my programmer preference. Also lots of interactive examples.

I think about this page because I have found myself wanting a page like it for other subjects. It'd be nice to have a page that aggregates them into a table of contents. A Primer on Heightfields, Simulating Lighting, Simulating Physics.

If you've gotten this far and liked the Primer on Bezier Curves, I recommend following the author, @TheRealPomax.

And if anyone has any suggestions around improving the Primer, I'm always up for thinking about ways to make it happen. What were the two things you had to piece together rather than being covered explicitly?

TBH it was years ago and I don't remember exactly. I was rasterizing 3D poly-curves to a heightfield. Saying that out loud isn't knocking anything loose in my memory though. If I think of it I'll be sure to let you know.

You also may have added things since I was heavily referencing the book. I don't recall the chapter "Working in 3D Normals" which was exactly what I was doing.

heh, yeah it may not update frequently, but it's still getting new content every half year or so =P

I guess one thing I'm not seeing that is useful for drawing poly-curves is knowing when you're past the end of the curve segment, and I don't see that. If I recall, it's mostly just a dot product check. >0 for one end, <0 for the other end.
