I am using control P5 and peasycam to create 3d agent based system. However, my controlP5's font is quite blurry. And I also don't know how could I move the camera to the center of my object in peasycam.
Here is the code:
- import processing.opengl.*;
import peasy.*;
import controlP5.*; - kWorld world1;
PeasyCam cam;
ControlP5 controlP5;
PMatrix3D currCameraMatrix;
PGraphics3D g3; - int population = 500;
- boolean alignment_enabled = false;
boolean coh_enabled = false;
boolean sep_enabled = false;
boolean wander_enabled = false;
boolean steer_enabled = false; - void setup(){
- size(1200,800,P3D);
//frameRate(30);
smooth();
world1 = new kWorld();
population();
g3 = (PGraphics3D)g;
cam = new PeasyCam(this, 2000);
controlP5 = new ControlP5(this);
control();
controlP5.setAutoDraw(false);
}- void population(){
- world1 = new kWorld();
for (int i = 0; i < population; i++) {
world1.addAgent(new kAgent(new PVector(random(150,width),random(0,height)), new PVector(random(-1,1),random(-1,1)),random(3,5), random(0.1,0.3)));
}
} - void draw(){
background(0);
//fill(100);
//rect(0,0,150,height);
fill(255);
PFont font;
font = loadFont("SansSerif.bold-10.vlw");
textFont(font,20);
textMode(SCREEN);
text("MODELT 2010",0,height-20);
//stroke(128);
//fill(255);
world1.run(); - gui();
}- void gui() {
currCameraMatrix = new PMatrix3D(g3.camera);
camera();
controlP5.draw();
g3.camera = currCameraMatrix;
} - void control(){
//population
controlP5.addSlider("population",0,2000,500,0,0,80,20).setId(1);
controlP5.controller("population").setLabel("population");

controlP5.controller("alignment").setLabel("alignment");
//cohesion
controlP5.addBang("cohesion",0,80,80,20).setId(3);
controlP5.controller("cohesion").setLabel("cohesion");
//separation
