There are many edge detectors, but I’m going to use the Canny Edge Detector, because I’m vaguely familiar with it and it’s quite well regarded. Here’s the image I’m going to use for the initial development: Step… Continue reading
I’ve got that itch again. The one that sits at the back of my head going “you haven’t done any cool programming in ages, don’t you think you should?” It’s an urge to go and work on a personal coding project, where I can experiment with stuff I find interesting,… Continue reading
My friend and I want to build an unmanned aerial vehicle. Unlike the predator drones, it will not be armed with missiles. This is an educational project for us; I’ve never done any proper “bare metal” coding before, or even very much hardware based stuff. Matt, however, is great at… Continue reading
Ten sample through each pixel: With more samples, the image eventually converges to this: There are still some bugs to work out: the above image had to be auto-leveled to correct the brightness. It starts out way to dark, for some reason.
Shamus Young was messing around with Perlin Noise, which turned out to be normal noise. I dug around in an old VM to find this image: The massive sphere in the background is procedurally textured with the Perlin Noise function, that is described in this paper: http://mrl.nyu.edu/~perlin/paper445.pdf It’s not the best… Continue reading
