45 | 46 | # Performance 47 | 48 | I worked hard on optimising the image comparator, so it should work pretty fast (_160 iterations/s at 50 triangles_), but there's stil a large handicap: 49 | ```java 50 | // Population.java, v1.4.4 51 | 52 | buffer = deepCopy(members); // < Copies the whole population array each time iterating 53 | 54 | buffer[MathUtil.random(buffer.length)].mutate(); // < Fine 55 | 56 | g.setColor(Color.WHITE); 57 | g.fillRect(0, 0, Polygonizer.WIDTH, Polygonizer.HEIGHT); // < Clear background, 58 | 59 | for (Polygon p : buffer) { // < Very, very bad! The speed of java graphics just isn't enough. 60 | g.setColor(p.color); // < Simply removing this line triples the speed 61 | g.fillPolygon(new int[] {(int) p.p1.x, (int) p.p2.x, (int) p.p3.x}, new int[] {(int) p.p1.y, (int) p.p2.y, (int) p.p3.y}, 3); // < Sloooooow 62 | } 63 | ``` 64 | I have no idea what to do here, since multithreading is not an option with the Graphics api. Hope i or somebody else will figure it out in the future. 65 | -------------------------------------------------------------------------------- /src/io/x666c/evoimg/web/WebStats.java: -------------------------------------------------------------------------------- 1 | package io.x666c.evoimg.web; 2 | 3 | import java.awt.Color; 4 | import java.awt.image.BufferedImage; 5 | import java.io.ByteArrayOutputStream; 6 | import java.util.Base64; 7 | 8 | import javax.imageio.ImageIO; 9 | 10 | import io.x666c.evoimg.EvoImage; 11 | import io.x666c.evoimg.gui.InfoPane; 12 | import spark.Request; 13 | import spark.Response; 14 | import spark.Spark; 15 | 16 | public class WebStats { 17 | 18 | private static boolean launched = false; 19 | 20 | private static String tss; 21 | private static String est; 22 | private static String usf; 23 | private static String usl; 24 | private static String pgr; 25 | private static String evr; 26 | private static String err; 27 | private static String gen; 28 | private static Color dcl; 29 | private static Color mcl; 30 | 31 | public static void launch() { 32 | Spark.port(80); 33 | Spark.get("/evo", WebStats::mainRoute); 34 | launched = true; 35 | } 36 | 37 | private static String mainRoute(Request req, Response resp) { 38 | String base64img = "ban"; 39 | final ByteArrayOutputStream out = new ByteArrayOutputStream(); 40 | try { 41 | BufferedImage copy = InfoPane.deepCopy(EvoImage.polygonizer.getImage()); 42 | ImageIO.write(copy, "png", out); 43 | } catch (Exception e) { 44 | e.printStackTrace(); 45 | } 46 | base64img = Base64.getEncoder().encodeToString(out.toByteArray()); 47 | 48 | String ret = "
