Siphon 経由で Madmapper にスケッチを送信できません。通常の「フレーム送信」スケッチは機能しますが、パラメーターをスケッチに取り込もうとすると、ビジュアライゼーションが表示されません。

私のコードを見て、何が間違っているのか教えてください：

   //Final Project
import codeanticode.syphon.*;


float rotation=0.1;
int num = 100, frms = 320;
float theta, time;
long rs; 
PGraphics canvas;
SyphonServer server;

//long: Use this datatype when you need a number to have a greater magnitude than can be 
//stored within an int.

void setup () {
  size(800, 800, P2D);
  canvas = createGraphics(800, 800, P2D);
  loop();
  server = new SyphonServer(this, "sublime");
};


void draw() {

  background(0);

canvas.beginDraw();
canvas.smooth();
  noStroke();
  fill(255, 255, 255, 20);
  rect(mouseX, mouseY, 50, 50);

  time = (frameCount % frms)/float(frms);
  paintQuads(); 
  theta += 2/TWO_PI/frms;
}



void paintQuads() {
  for (int i=0; i<num; i++) {
    fill(0);
    stroke(255);
    float r = random(-.5, .5);
    float sz = random(5, 15);
    resetMatrix(); //  Replaces the current matrix with the identity matrix. 
    // This effectively clears all transformation functions set before it.



    //multiply the quads

    //Translate
    //Specifies an amount to displace objects within the display window. 
    //The x parameter specifies left/right translation, the y parameter specifies up/down
    //translation, and the z parameter specifies translations toward/away from the screen. 
    //Using this function with the z parameter requires using P3D as a parameter in 
    //combination with size as shown in the above example. 


    translate(random(width), random(height));
    rotate(r);
    rotate(rotation); 

    //images

    noStroke();

    fill(255, 0, 0, 70);
    quad(38, 31, 86, 20, 69, 63, 30, 76);

    fill(255, 210, 0, 10);
    quad(width-9, height-9, 86, 20, 69, 63, 30, 76);

    fill(255, 0, 0, 30);
    ellipse(36, 36, 16, 16);

    fill(50, 46, 100, 20 );
    quad(46, 20, 14, 14, 46, 20, 14, 14);

    fill(50, 46, 100, 75);
    quad(50, 0, 12, 12, 50, 0, 12, 12);

    rotation=rotation+0.5;
  }
  canvas.endDraw();
  image(canvas, 0, 0);
  //send canvas to Syphon
  server.sendImage(canvas);
}

ありがとうございました！-k

PGraphics インスタンスを適切に使用していないようです: 一部の呼び出しはそれを使用し、一部はメイン スケッチに描画しますが、Syphon に送信するキャンバス PGraphics は使用しません。

server.sendScreen();1つの簡単な修正は、代わりに呼び出すことですserver.sendImage();

このように、Processing で表示されるものは、Syphon を介して MadMapper で表示されるものです。 サイフォン マッド マッパー プレビュー

または、PGraphics 呼び出しを修正できます。
