またも昨日の日記.

他の仕事で結局ほとんどできず.

ただ, list8.3を少しだけいじって仕事で使用したので少し楽しかった.

PImage img; int _numChildren = 6; int _maxLevels = 6; Branch _trunk; void setup() { size(3000,2000); // img = createImage(width, height, ARGB); // colorMode(RGB, 255, 255, 255, 128); background(255, 0); noFill(); smooth(); newTree(); } void newTree() { _trunk = new Branch(1, 0, width/2, height/2); _trunk.drawMe(); } void draw() { background(255, 0); _trunk.updateMe(width/2, height/2); _trunk.drawMe(); } void keyPressed() { if (keyCode == ENTER) { saveFrame( "img#####.png"); // img.save("imgT#####.png"); } } class Branch { float level, index; float x, y; float endx, endy; float strokeW, alph; float len, lenChange; float rot, rotChange; Branch[] children = new Branch[0]; Branch(float lev, float ind, float ex, float why) { level = lev; index = ind; strokeW = (1/level) * 10; alph = 255 / level; len = (1/level) * random(500); rot = random(360); lenChange = random(10) - 5; rotChange = random(10) - 5; updateMe(ex, why); if (level < _maxLevels) { children = new Branch[_numChildren]; for (int x=0; x<_numChildren; x++) { children[x] = new Branch(level+1, x, endx, endy); } } } void updateMe(float ex, float why) { x = ex; y = why; rot += rotChange; if (rot > 360) { rot = 0; } else if (rot < 0) { rot = 360; } len -= lenChange; if (len < 0) { lenChange *= -1; } else if (len > 500) { lenChange *= -1; } float radian = radians(rot); endx = x + (len * cos(radian)); endy = y + (len * sin(radian)); for (int i=0; i<children.length; i++) { children[i].updateMe(endx, endy); } } void drawMe() { if (level > 1) { strokeWeight(strokeW); // stroke(0, alph); stroke(0, 255, 0, alph); // stroke(random(255), random(255), random(255), alph); fill(255, alph); line(x, y, endx, endy); ellipse(endx, endy, len/12, len/12); } for (int i=0; i<children.length; i++) { children[i].drawMe(); } } }

今日は研究の仕事が溜まっているので他の内容はできないかな...

とりあえず, 進んでも進まなくても, 一日の終りに日記を書くことだけはやるようにしよう.
