hello,

i am new in processing.
i have a problem concerning my camera position. i want to circle it around my object by using the mouse or keyboard. i have a center point (x, y, z) and radius. and want the camera to recognize the past positions of my object.

here is my code:

import processing.opengl.*;

Essen e[] = new Essen[1];
Kacken k[] = new Kacken[1];
Schlafen s[] = new Schlafen[1];

color white = color(255, 255, 255, 80);
color red = color(255, 0, 0, 50);
color green = color(0, 255, 0, 50);
color blue = color(0, 0, 255, 50);
color back = color(95, 95, 95);



void setup () {
 size (700, 700, P3D);
 background (back);
 stroke (white);
 smooth();
 noLoop();

 for (int i=0; i < e.length; i++) {
   float x = random (250, 450);
   float y = random (250, 450);
   float z = random (250, 450);
   e[i] = new Essen (x, y, z);
 }

 for (int i=0; i < k.length; i++) {
   float x = random (250, 450);
   float y = random (250, 450);
   float z = random (250, 450);
   k[i] = new Kacken (x, y, z);
 }

 for (int i=0; i < s.length; i++) {
   float x = random (250, 450);
   float y = random (250, 450);
   float z = random (250, 450);
   s[i] = new Schlafen (x, y, z);
 }
}

void draw () {
 //background (back);
   smooth();
   

   
 for (int i=0; i < e.length; i++) {
   e[i].move ();
   point (e[i].position.x, e[i].position.y, e[i].position.z);

 }

 for (int i=0; i < k.length; i++) {
   k[i].move ();
   point (k[i].position.x, k[i].position.y, k[i].position.z);
 }

 for (int i=0; i < k.length; i++) {
   s[i].move ();
   point (s[i].position.x, s[i].position.y, s[i].position.z);
 }

 for (int i=0; i < e.length; i++) {
   e[i].move ();
   stroke(red);
   line(e[i].position.x, e[i].position.y, e[i].position.z, k[i].position.x, k[i].position.y, k[i].position.z);
   stroke(green);
   line(k[i].position.x, k[i].position.y, k[i].position.z, s[i].position.x, s[i].position.y, s[i].position.z);
   stroke(blue);
   line(s[i].position.x, s[i].position.y, s[i].position.z, e[i].position.x, e[i].position.y, e[i].position.z);
 }
}

void mousePressed() {
 loop();
}

thanks for your help

thank you.

as i wrote, i am new in processing.
so might you show me a possiblity to integrate this in my code please.
