I always love reading artists rules of thumb for how to use curves and surfaces in design. I'm surprised how much performance is a consideration. In CAD the degree of the surfaces are not really a big deal any more, surface degrees of 3 are most common, in some fields you get up to degree 7 or 8. However there are generally a lot fewer surfaces in CAD then there are curves in a page full of fonts. A couple of comments: > to convert quadratic to cubic, the best the program could do is an approximation of the original outline You can convert quadratic to cubic exactly (the algorithm is called degree elevation). Cubic to quadratic must be an approximation, but the artist seems happy with it and designs around it (Bezier endpoint at inflection point, etc). The other comments about file size and computation still hold. > Since we still need a worldwide network of computers just to find some more pi digits, no perfect circles to anyone Hmm, you can get perfect circles with rational Beziers, but I don't know if those are supported in fonts. I know they're not supported in svg.
