▌pd小練習_[repeat]及[separator]的控制

GEM-TEST from kicko on Vimeo.


這個小動畫本來是這次openframeworks工作坊時的小練習

而我則是用puredata用相同的原理將它做出來

以下是openframeworks的程式碼
----------------------------------------------------
#include "testApp.h"
#define NUM 24

ofPoint pos[NUM];
float angle;
ofPoint rot;

//--------------------------------------------------------------
void testApp::setup(){
    ofBackground(0, 0, 0);
    ofSetFrameRate(60);
    ofSetCircleResolution(64);
}

//--------------------------------------------------------------
void testApp::update(){
    angle += 0.02;
    for (int i=0; i
        pos[i].x = sin(angle*i/NUM)*200 ;
        pos[i].y = cos(angle*i/NUM)*200 ;
    }
}

//--------------------------------------------------------------
void testApp::draw(){
    ofSetColor(31, 127, 255);
    ofNoFill();
    ofTranslate(ofGetWidth()/2,ofGetHeight()/2 );
    ofRotateX(rot.x);
    ofRotateY(rot.y);
    for (int i=0; i
        ofCircle(pos[i].x, pos[i].y, i*200.0/NUM);
    }
}
------------------------------------------------------------------

以下則是puredada的做法：
