Code	//v1 3D surface with colored lighting //v2 added automatic rotation //v2.1 added shadows //v2.2 fixed rotation glitch (noise pattern wasn't rotating) //v2.3 adjusted colors //v3 improved performance, shadows no longer rotate along with surface, stop rotation with space bar, and freeze time with mouse. //v3.1 small fix //v4.0 Massive performance increases overall (massive credit to jocopa3) frameRate(24); translate(width/2, height/2); colorMode(HSB); noiseDetail(2, 0.4); noiseSeed(0); var time = 0; var rot = 0; var tls = 18; var res = 50/constrain(tls, 10, 40)2; var draw = function() { var Shadow = 30; // Define shadow here var w = width; var sc = w/400; var tiles = 18; var Res = res; var Rot = rot; // Re-define rot var Time = time; // Re-define time var Sin = sin; var Cos = cos; // Re-define all functions used var Noise = noise; var pVector = PVector; var Quad = quad; var Fill = fill; background(255, 0, 200); noStroke(); time += keyIsPressed?0:1; var hue = time%255; rot += (mouseIsPressed?(mouseX-pmouseX)/2:0.5); // Calculate cos and sin only once var trigRot = [Cos(rot), Sin(rot)]; // Define functions in draw loop instead of outside of the draw loop var d3 = function(x, y, z){ var z2 = z/w; return new pVector(x/z2, y/z2-zsc); }; var noiseWave = function(x, z, h){ return Noise(x/64, z/64,Time/64)h; }; var rotatePoint = function(pX, pY, oX, oY) { // Use pre-calculated cos and sin rather than re-calculating for every point return [trigRot[0](pX-oX)-trigRot[1](pY-oY)+oX, trigRot[1](pX-oX)+trigRot[0](pY-oY)+oY]; }; for (var d = -1; d <= 1; d += 2){ var rd = Resd; for (var x = 50d; xd >= d; x -= rd){ for (var z = 150; z > 50; z -= Res){ var zPlusRes = z + Res; var xPlusRes = x + Res; var p1p = rotatePoint(x, z, 0, 100); var p2p = rotatePoint(xPlusRes, z, 0, 100); var p3p = rotatePoint(xPlusRes, zPlusRes, 0, 100); var p4p = rotatePoint(x, zPlusRes, 0, 100); var y1 = noiseWave(x, z, 64); var y2 = noiseWave(xPlusRes, z, 64); var y3 = noiseWave(xPlusRes, zPlusRes, 64); var y4 = noiseWave(x, zPlusRes, 64); var p1 = d3(p1p[0], y1, p1p[1]); var p2 = d3(p2p[0], y2, p2p[1]); var p3 = d3(p3p[0], y3, p3p[1]); var p4 = d3(p4p[0], y4, p4p[1]); var brightness = 128+(y1-y2)trigRot[0]Shadow+(y1-y4)trigRot[1]Shadow; Fill(hue, 200, brightness); Quad(p1.x, p1.y, p2.x, p2.y, p3.x, p3.y, p4.x, p4.y); } } } };
