That's a nice paper. Filed!

Not entirely true, but not entirely false either: the quadratic has degenerate cases where it can't be represented by a single quadratic polynomial, and regardless of the order, each dimension in a nth order Bezier curve is guaranteed

3d Beziers have been a thing for a long time already though! In modelling, NURBS surfaces are typically used (the non-uniform rational B-spline, where the rational B-spline part is a "rationalised" bezier, which is a whole section

Only OpenType with TrueType outlines (the common .ttf file) do - lines and quadratic curves is all you get. OpenType fonts with CFF/Type2 outlines (the equally common .otf files) use cubic curves instead, with an insanely rich instruct

Quadratic curves get very "pointy" with increased curvature, so you're trading "easy to draw a single smooth curve" (fairly meaningless in vector work) for "a genuine hassle to line up the consecutive curves th

although as a Springer book it's a bit pricey =( (I'll be trying to add rational B splines and NURBS to the primer soon..ish... there's a few other topics that still need expanding first)

nice, file it and I'll see how easily I can get on that.

well, close to. Processing is based on Java, but has a simplified syntax, different visibility model, and different scoping rules. Primarily due to how pde source code gets aggregated into a single class which can be compiled to run in the

This isn't actually JS, it's Processing, so the idea is that this will work in the browser by virtue of a library that will run Processing source code in the browser. If you want to do the programming offline, just hit up processi

there's a codebase this builds on, simply called codebase.pde, in the same dir as the tutorial.

Nintendo generally doesn't care in the slightest if their assets are used for things like this. In the US and many other jurisdictions Nintendo might care about this is simply fair use. It's an educational resource without even a

This is great for the less popular star treks... got one for Voyager, too?

needs a spell check though, there's quite a bit of copy that has spelling or grammar mistakes, or missing words.

I just read that sentence, and it doesn't explain anything. It just says they're not what he likes, so here's another one that might work: http://www.mucommander.com/

At least for the "de Casteljau" algorithm that Jason also demonstrates in this HN link (in my article, it's http://processingjs.nihongoresources.com/bezierinfo/#splitti... )

No, I'm pretty sure I made them animated, and added a big red text over the sketches to make sure you know they are, saying "Animated sketch, click to play" =D
