What?  Were you expecting some kind of unicorn perhaps? Is it teatime yet? Or what else might be happening? I managed to get the OpenGL code working for the latest revision of the hair drawing routines, using the "Digital DNA" - approach as I described earlier. This will also work quite nicely for blades of grass, or maybe even Velcro-like materials. Love the new NVIDIA graphics!

As I said earlier, IIRC - real hair just as often as not will have an elliptic cross-section. which is one of the things that helps curly hair be curly, and so on.  This is why IMHO, using the DNA drawing code that I figured out from drawing gears is so useful.  Yet if you ever read one of my other projects, entitled "The Money Bomb!", you might remember this 3-D printed gear, which I somehow managed to print using a commercial 3-D printer on the one hand, but so also using an OBJ file that was also therefore created, nonetheless - entirely from scratch.

So, 50,000 or so lines of code later, I still can't 3-D print artificial trees for a model railroad that I will never own.  Oh well.  Maybe a nice icosahedron?  Or a golf ball?  Not sure how well that one would work out.  The idea of printing or milling at the nanoscale, whatever that might mean, does have some appeal.  Maybe.  It is so nice to have a project that otherwise does nothing in any case.   Where their final product contains no Arduino, nor any other circuitry, no batteries, no source of power.  It doesn't even need to blink.  It is sufficient for it to merely exist, at least for now.
