Further experiments with triangle generator.

I like the fire like colours in all of these outputs. As I stated before I like the idea that these outputs would be very time consuming and tedious to create in photoshop or illustrator but with code they can be created within a matter of seconds. 

float med_mouseX=mouseX;

float med_mouseY=mouseY;

float old_mouseX=0;

float old_mouseY=0;

float red=random(0,255);

void setup() {

  size(1000,1200);

  background(255);

}

void draw(){

  noStroke();

  med_mouseX=(mouseX+pmouseX)*0.5+random(-400.0,400.0);

  med_mouseY=(mouseY+pmouseY)*0.5+random(-400.0,400.0);

  if(mousePressed){

    if(old_mouseX==0){

      old_mouseX=mouseX;

    }

    if(old_mouseY==0){

      old_mouseY=mouseY;

    }

    fill(random(0,255),0,0,random(0,255));

    beginShape();

      vertex(mouseX,mouseY);

      vertex(med_mouseX,med_mouseY);

      vertex(pmouseX,pmouseY);

    endShape();

   

  fill(random(0,255),0,0,random(0,255));

    beginShape();

      vertex(med_mouseX,med_mouseY);

      vertex(pmouseX,pmouseY);

      vertex(old_mouseX,old_mouseY);

    endShape();

     

    old_mouseX=med_mouseX;

    old_mouseY=med_mouseY;

  }

}

void mouseClicked() {

  med_mouseX=mouseX;

  med_mouseY=mouseY;

  old_mouseX=mouseX;

  old_mouseY=mouseY;

}

void keyPressed(){

  if(key=='s'){

    saveImage();

  }

  if(key=='x'){

    background(255);

  }

  if(key=='e'){

    filter(ERODE);

    filter(ERODE);

    filter(ERODE);

  }

  if(key=='d'){

    filter(DILATE);

    filter(DILATE);

    filter(DILATE);

  } 

}

 void saveImage() {

  String fileName = timeStamp()+".tiff";

  PImage imageSave = get(0,0,width,height);

  imageSave.save(fileName);

}

  

String timeStamp() {

 String timestamp = year()+"_"+month()+"_"+day()+"_"+minute()+"_"+second()+"_"+millis();

 return timestamp;

}
