Load image as background of sphere

georgia

I'm trying to make a sphere of size 30 with an image as the background. How do I do this? I'm using the directionalLight() method, so I think I need to incorporate the image somewhere in there. Anything helps!

Chrisir

just say background(imgBg);

load imgBg in setup()

nothing to do with your lights

and now show your code...

I tried that, but I think there's an issue because the image I'm trying to load onto the sphere isn't the same size as the sphere...Here's my code.

int y;
PImage bg;
PImage spherebg;

void setup(){
  size(1024, 576, P3D);
  noStroke();
  fill(204);
  bg=loadImage("space.jpg");
  spherebg=loadImage("sun1.jpg");

  println(inventory);
  noLoop();
  fill(0);
  textAlign(CENTER);
}

void draw() {
  noStroke(); 
  background(bg);
  buildSphere();
}

void buildSphere(){
  float dirY = (mouseY / float(height) - 0.5) * 2;
  float dirX = (mouseX / float(width) - 0.5) * 2;
  directionalLight(99, 0, 66, -dirX, -dirY, -1); 
  translate(width/2 - 100, height/2, 0); 
  sphere(30); 
  background(spherebg);
  translate(200, 0, 0); 
  sphere(80); 
}

this should be the first line in draw() to get the stars

background(bg);

this command can not give you the texture for the sphere though.

You seem to mix this up a little: background stars and texture of the sphere.

E.g. this line

background(spherebg);

makes no sense: background can not make the sphere texture.

but you see how it is done in the other thread, ok...?
