Code	/** * I'm Dalendrion (not my actual name), born in 1983 in the Netherlands. * * My first encounter with programming was when a friend asked me if I would be interested in learning it. * Not knowing what I was about to get into I said "Err, sure?" * That was the best decision of my life. * I loved it so much that I started an education in computer science * even though I almost had (and now have) a Bachelor's degree in chemistry... * * I love math, logic and problem solving. Programming turns all that into something creative. * And that's flipping awesome. / / A sun! Give it time to load. Once the counter reaches 360, the animation will speed up. There's a special event every 6 minutes! See the original at: * https://www.khanacademy.org/computer-programming/animated-sun/6526591131451392 / // Larger steps makes it load faster, but makes the animation less smooth. var step = 5; //The size of the sun. var toScale = 2; var noiseVal; var noiseScale = 0.06; translate(width / 2, height / 2); scale(toScale); imageMode(CENTER); var lon0 = 0; var lat0 = 0; var R = 100 PI / TWO_PI; var s = 1.6; var color1 = [225, 128, 10]; var color2 = [225, 192, 10]; var planet = []; var draw = function() { background(0); if(planet.length < 360 / step) { var cosLat0 = Math.cos(lat0); var sinLat0 = Math.sin(lat0); var atm = 25; for(var i = 0; i < atm; i+=1) { var _h = (atm - i); noStroke(); var _p = atm / _h / 10; fill(_p * color1[0], _p * color1[1], _p * color1[2], 100); ellipse(0.5, 0.5, 64 + _h, 64 + _h); } for(var y = -50; y < 50; y++) { var lat = map(y, -50, 50, -HALF_PI, HALF_PI); var cosLat = Math.cos(lat); var sinLat = Math.sin(lat); for(var x = -50; x < 50; x+=0.5) { var lon = map(x, -50, 50, -PI, PI) - lon0; var cosLon = Math.cos(lon); var sinLon = Math.sin(lon); noiseDetail(5.5, 0.70); noiseVal = noise(x * noiseScale0.7, y noiseScale); var _x = R * Math.cos(lat) * Math.sin(lon); var _y = R * cosLat0 * sinLat - sinLat0 * cosLat * cosLon; var _z = cosLon; var r = Math.sqrt(_x_x + _y_y); var c = Math.asin(r / R); if(_z >= 0 && c >= 0) { var col1 = color(noiseVal * color2[0], noiseVal * color2[1], noiseVal * color2[2]); stroke(col1); var frostLat = radians(35);/* if(abs(lat) > frostLat) { stroke(lerpColor(col1, color(255), constrain( (abs(lat) - frostLat) / (0.5(PI - frostLat)), 0, 0.5) ) ); }/ point(_x/s, _y/s); } } } lon0 += radians(step); filter(BLUR); planet.push(get(width / 2 - 50toScale, height / 2 - 50toScale, 100toScale, 100toScale)); text(planet.length * step, 150/toScale, 150/toScale); } else { var im = planet[floor(millis() / (20step)) % planet.length]; image(im, 0, 0, im.width / toScale, im.height / toScale); } fill(0); noStroke(); if(sin(millis() / 1000) > 0) { ellipse(cos(millis() / 1000) 100, 0, 33 * toScale, 33 * toScale); } };
