Whoah.
God damn it, I thought I was finished!
Related: I coded up a Mandelbrot generator from the pseudocode here: http://beej.us/blog/data/mandelbrot-set/. It does something, but not a lot (I get mainly red, with a couple of splotches of yellow-green here and there) and each frame takes in the order of seconds to render. Am I doing something wrong (with the scale, maybe?), or is this the result you’d expect from a naive floating-point implementation of the linked algorithm on a Teensy?
I converted a few of the above tweetable formulas to be displayed along a single strand of LED’s, but the results were unfortunately rather meh. As for Mandelbrot sets, as much as I love them (and still have my Aug '85 issue of Scientific American), I just don’t see this as something I could animate on an Arduino. Will continue to keep an eye out . . .
Yeah, I had a play around and didn’t really get much satisfactory in 2D either. Part of the problem was the spec was for 1024-bit RGB values (why why why?!) and in addition to that I had trouble getting the “scale” right, from the original 1024x1024 grid to my ~20x36 grid.
My take on it is to project given field on to what leds I have then translate, rotate, path follow and zoom around the fields.
I’m a tad bit short of that at the moment, but that is the plan.
Pretty well what Mein said: In my case, I scaled the x axis to the number of LED’s I have and then ran the algorithm through the y axis and then displayed for each increment. I didn’t, however rotate and zoom around.
