How to create a blob detection with an sphere following the blob.

kujn14

Hello, I need help to create code with a blob detection with an sphere following the blob or a circle detection with an sphere following the circle. Is it possible for you to help? If you are interested in helping, I can elaborate further. I'm new to coding in processing.

JFGI?

@TfGuy44 Yes, I did look at that. Can you help me to get a sphere instead of a rect?

See, "How do I draw a sphere at a given position?" is a MUCH easier question than "How do I do blob detection?". We're talking way, WAY easier here.

void setup(){
  size(400,400,P3D);
  ortho();
}

void draw(){
  background(0);
  // Set your own (x,y) however you like - maybe with blob detection.
  float x = mouseX;
  float y = mouseY;
  // Draw sphere at (x,y)
  pushMatrix();
  lights();
  translate(x,y);
  scale(30);
  fill(255,0,0);
  noStroke();
  sphere(1);
  popMatrix();
}

@TfGuy44 Thank you! I'll try to use this.
