Hello!

I produced a simple code that flies a 3D camera through a box when you press cursor UP.
The eye flies into the screen through the box.
The position of the center (LookAt ) is always 12 pixels in front of the eye.
You move the camera via cursor UP and DOWN.
But at the center of the box all kinds of weired stuff happens to the box (diagonal lines and stuff). Why? Program error?
Code below.

Thanks!

Greetings to all,

Chris



float fillValX = 2;  
float CameraAdd = 5;

void setup()
{
 size(1100, 900, P3D);
 background(100);
 smooth();
 noFill();
 stroke(256, 0, 0);
} // setup

void draw()
{
 camera ( width/2.0, height/2.0, fillValX,
 width/2.0+1, height/2.0+1, fillValX+12,
 0, 1, 0 ) ;              
 background(0);
 translate(458, 428, 1320);
 box(440);
 translate(458, 428, 1620);
 box(40);
 println(fillValX);
} // draw

void keyPressed() {
 if (key == CODED) {

   if (keyCode == UP) {
     fillValX += CameraAdd;
   }
   else if (keyCode == DOWN) {
     fillValX += -CameraAdd;
   }
 }
 else {  
   // not key == CODED
 }
} // keyPressed
