‣ 次週(1月23日)の授業で発表してください

先週の復習

SuperCollider client for Processing‣ ProcessingとSuperColliderの連携には、SuperCollider client for Processingが便利

‣ OSCp5よりも簡単に、SuperColliderとProcessingの連携が可能となる

SynthDef("test_inst",{ arg freq=440, length=1.0, amp=0.5; var env, out; env = Env.perc(0.01, length); out = SinOsc.ar([freq,freq*1.001]) * EnvGen.kr(env, doneAction:2) * amp; Out.ar(0, out); }).store;

SuperCollider client for Processing‣ SuperCollider側: 「test_inst」を定義

import supercollider.*; import oscP5.*; !Synth synth; !void setup () { size(600, 400); } !void draw() { background(0); } !//マウスクリックに反応 void mouseReleased() { //新規に楽器を定義(まだ生成はされず) synth = new Synth("test_inst"); //引数を設定 synth.set("amp", 0.5); synth.set("freq", map(mouseY, height, 0, 20, 8000)); //楽器を生成 synth.create(); }

SuperCollider client for Processing‣ Processing側: クリックで音が鳴るように

SuperCollider client for Processing‣ たとえば、ここに円が拡がるアニメーションをつけてみる

import supercollider.*; import oscP5.*; !Synth synth; int NUM = 100; float[] radius = new float[NUM]; PVector[] pos = new PVector[NUM]; int counter = 0; !void setup () { size(800, 600); frameRate(60); noFill(); stroke(31, 127, 255); strokeWeight(3); for (int i = 0; i < NUM; i++) { radius[i] = 0; pos[i] = new PVector(width*2, width*2); } }

SuperCollider client for Processing‣ Processing側:

void draw() { background(0); for (int i = 0; i < NUM; i++) { ellipse(pos[i].x, pos[i].y, radius[i], radius[i]); radius[i] += 1; if(radius[i] > width*1.5){ radius[i] = 0; pos[i].x = width*2; pos[i].y = width*2; } } } !void mouseReleased() { synth = new Synth("test_inst"); synth.set("amp", 0.5); synth.set("freq", map(mouseY, height, 0, 20, 8000)); synth.create(); int n = counter % NUM; radius[n] = 0; pos[n].x = mouseX; pos[n].y = mouseY; counter++; }


SuperCollider client for Processing‣ 完成!!

SuperCollider client for Processing‣ SuperColliderの楽器はそのままで、さらに別の例

import supercollider.*; import oscP5.*; !int NUM = 400; //配列の数 //位置のベクトルの配列 PVector[] location = new PVector[NUM]; //速度のベクトルの配列 PVector[] velocity = new PVector[NUM]; //塗りの色の配列 color[] col = new color[NUM]; //円の大きさ(直径)の配列 float[] diameter = new float[NUM]; !void setup() { size(640, 480); //640x480pixelの画面を生成 frameRate(60); //フレームレート noStroke(); for (int i = 0; i < NUM; i++) { //配列の数だけ繰り返し //位置のベクトルの初期設定 location[i] = new PVector(random(width), random(height)); //速度のベクトルの初期設定 velocity[i] = new PVector(random(-4, 4), random(-4, 4)); //色の初期設定 col[i] = color(random(255), random(255), random(255), 127); //大きさの初期設定 diameter[i] = random(3, 40); } }


void draw() { background(15); //背景を描画 //配列の数だけ繰り返し for (int i = 0; i < NUM; i++) { fill(col[i]); //色を指定 //指定した位置に円を描画 ellipse(location[i].x, location[i].y, diameter[i], diameter[i]); //位置のベクトルに速度のベクトルを加算、次の位置になる location[i].add(velocity[i]); //もし画面の左端、または右端に到達したら if ((location[i].x > width) || (location[i].x < 0)) { velocity[i].x *= -1; //X方向のスピドを反転 playSynth(location[i].x, location[i].y); } //もし画面の下端、または上端に到達したら if ((location[i].y > height) || (location[i].y < 0)) { velocity[i].y *= -1; //Y方向のスピードを反転 playSynth(location[i].x, location[i].y); } } } !void playSynth(float x, float y) { //新規に楽器を定義(まだ生成はされず) Synth synth = new Synth("test_inst"); //引数を設定 synth.set("amp", 0.1); synth.set("freq", map(x, height, 0, 20, 8000)); //楽器を生成


!void playSynth(float x, float y) { //新規に楽器を定義(まだ生成はされず) Synth synth = new Synth("test_inst"); //引数を設定 synth.set("amp", 0.1); synth.set("freq", map(x, height, 0, 20, 8000)); //楽器を生成 synth.create(); }


SuperCollider client for Processing‣ ボールのバウンドに反応

import supercollider.*; import oscP5.*; !Synth synth; int NUM = 100; float[] radius = new float[NUM]; PVector[] pos = new PVector[NUM]; int counter = 0; !void setup () { size(800, 600); frameRate(60); noFill(); stroke(31, 127, 255); strokeWeight(3); for (int i = 0; i < NUM; i++) { radius[i] = 0; pos[i] = new PVector(width*2, width*2); } }


いろいろサンプル
