If youre using an ancient browser, on the other hand, you may just see a message that WebGL is not supported. In the former case, upgrade your hardware; in the latter, upgrade your browser! /p> iframe classifrm-right width320 height180 srchttps://www.shadertoy.com/embed/WslSRH?guitrue&t10&pausedfalse&mutedfalse allowfullscreen>/iframe> p>Hover over one and youll see a play/pause button, a fullscreen option and a rewind facility. In the bottom one (Yin-Yang), click in the right half for more symmetry, the left for less./p> p>Instead of your CPU computing the colours of the all pixels to be displayed for every screen image (ideally about sixty times a second), it sends little programs called shaders to the GPU, which the GPU itself then runs in parallel thousands of times on very specialised processors , to generate every pixel value for the viewport./p> iframe classifrm-left width320 height180 srchttps://www.shadertoy.com/embed/4tVyDd?guitrue&t10&pausedfalse allowfullscreen>/iframe> p>By manipulating mathematical functions according to the position of the pixel on the screen and the time since the animation started, its possible to generate all sorts of interesting effects./p> p>I have only recently discovered this form of programming, and it gives me great joy to have found a new way of making art from mathematics./p> p>But shaders are not just about art, or even just about rendering data to the screen. The ability of graphics processors to do thousands of calculations in parallel gives them applications in Bitcoin mining and artificial intelligence, iframe classifrm-right width320 height180 srchttps://www.shadertoy.com/embed/MtcfzM?guitrue&t10&pausedfalse allowfullscreen>/iframe> for example. In fact, some of the newest GPUs have special instructions built into their hardware which facilitate the computations needed by neural networks, so training such networks on very large datasets is far more feasible. /p> p>The use of GPUs and massive parallelisation of computation for all sorts of other applications is a hot area of research currently, and we can expect interesting developments over the next few years. Maybe people will soon forget why theyre called GPUs, as the original specialisation of the word disappears and they become really useful general-purpose workhorses utilised for a wide range of tasks in our digital lives./p> h1 classfloat-right>For more info see a classbig-link href/shaders>Shaders/a>/h1> /main> aside classinfo> p class intro> This is the website of John Lynch, software developer, mathematician, digital artist, musician, composer, gardener, builder, aficionado of good coffee. /p> p class intro> To find out more about me and what I do, hit on one of the links above. :) /p> h2>Voronoi Diagrams/h2> iframe classifrm-right width320 height180 srchttps://www.shadertoy.com/embed/XltfzM?guitrue&t10&pausedfalse allowfullscreen>/iframe> p> You are looking at an animated Voronoi diagram. They arise from plotting a number of fixed points, then plotting the loci of points that are equidistant from the two nearest fixed points. Here Im colouring according to the distance of the closest fixed point, and animating the results by varying some parameters with time. Voronoi diagrams result in tesselations of the plane, and have a wide range of applications ranging from fluid dynamics, the study of bone growth, forest growth patterns, rainfall measurement, aviation, video game collision detection and a host more! The animation is coded in a "shader", a small program which runs entirely on your graphics chip. For more info see a href/shaders>here/a>. /p> p> span classnote>Mathematical note:/span> distance may be defined in terms of any valid distance metric, but generally some form of Minkowski distance, such as Euclidean distance (order 2) or Manhattan distance (order 1).
