Sorry if this is a stupid question but I'm still very new at this and have no idea what I'm doing.

I'm trying to apply a texture to a shape I've created. If I load up the code right off the site it works fine.


noStroke();
PImage a = loadImage("myimage.jpg");
textureMode(NORMALIZED);
beginShape();
texture(a);
vertex(10, 20, 0, 0);
vertex(80, 5, 1, 0);
vertex(95, 90, 1, 1);
vertex(40, 95, 0, 1);
endShape();

But if I try and put it into code that loops I just get a black screen. It seems like it should work the same, but it's not. What am I doing wrong?

PImage myimage;

void setup(){
 size(300, 300, P3D);
 noCursor();
 noStroke();
 noFill();
 noLoop();
 textureMode(NORMALIZED);
 myimage = loadImage("myimage.gif");
}

void draw(){
 background(0);

 beginShape(QUADS);
 texture(myimage);
 vertex(10, 20, 0, 0, 0);
 vertex(80, 5, 0, 1, 0);
 vertex(95, 90, 0, 1, 1);
 vertex(40, 95, 0, 0, 1);
 endShape();
}
