I really need some help please(cube with pictures)

in Programming Questions • 3 years ago

i have this code which makes a cube with only one picture on all 6 sides so i want to make this cube have a different pictures on each side. This cube also moves as you move your mouse over it. If you want to send me a code assum ethe other pictures are called pic1.jpg, pic2.jp, etc. PS- this was based on the TextureCube example if that is neccesary.

PImage pix;
float rotx = PI/4;
float roty = PI/4;

void setup()
{
size(640, 360, P3D);
pix = loadImage("pic.JPG");
textureMode(NORMALIZED);
fill(255);
stroke(color(44,48,32));
}

void draw()
{
background(0);
noStroke();
translate(width/2.0, height/2.0, -100);
rotateX(rotx);
rotateY(roty);
scale(90);
TexturedCube(pix);
}

void TexturedCube(PImage pix) {
beginShape(QUADS);
texture(pix);

// +Z "front" face
vertex(-1, -1, 1, 0, 0);
vertex( 1, -1, 1, 1, 0);
vertex( 1, 1, 1, 1, 1);
vertex(-1, 1, 1, 0, 1);

// -Z "back" face
vertex( 1, -1, -1, 0, 0);
vertex(-1, -1, -1, 1, 0);
vertex(-1, 1, -1, 1, 1);
vertex( 1, 1, -1, 0, 1);

// +Y "bottom" face
vertex(-1, 1, 1, 0, 0);
vertex( 1, 1, 1, 1, 0);
vertex( 1, 1, -1, 1, 1);
vertex(-1, 1, -1, 0, 1);

// -Y "top" face
vertex(-1, -1, -1, 0, 0);
vertex( 1, -1, -1, 1, 0);
vertex( 1, -1, 1, 1, 1);
vertex(-1, -1, 1, 0, 1);

// +X "right" face
vertex( 1, -1, 1, 0, 0);
vertex( 1, -1, -1, 1, 0);
vertex( 1, 1, -1, 1, 1);
vertex( 1, 1, 1, 0, 1);

// -X "left" face
vertex(-1, -1, -1, 0, 0);
vertex(-1, -1, 1, 1, 0);
vertex(-1, 1, 1, 1, 1);
vertex(-1, 1, -1, 0, 1);

endShape();
}

void mouseDragged() {
float rate = 0.01;
rotx += (pmouseY-mouseY) * rate;
roty += (mouseX-pmouseX) * rate;
}

You're already pretty close.

Just load all size jpgs into six different PImages in your setup()

In your draw() method, just call beginShape/endShape for EACH face -- not one for all six -- and call texture() differently for each one.

This is what i have so far:

PImage pix;
PImage pix2;
PImage pix3;
PImage pix4;
PImage pix5;
PImage pix6;
float rotx = PI/4;
float roty = PI/4;

void setup()
{
size(640, 360, P3D);
pix = loadImage("pic.JPG");
pix2 = loadImage("pic2.JPG");
pix3 = loadImage("pic3.JPG");
pix4 = loadImage("pic4.JPG");
pix5 = loadImage("pic5.JPG");
pix6 = loadImage("pic6.JPG");
textureMode(NORMALIZED);
fill(255);
stroke(color(44,48,32));
}

void draw()
{
background(0);
noStroke();
translate(width/2.0, height/2.0, -100);
rotateX(rotx);
rotateY(roty);
scale(90);
TexturedCube(pix,pix2,pix3,pix4,pix5,pix6);
}

void TexturedCube(PImage pix,PImage pix2,PImage pix3,PImage pix4,PImage pix5,PImage pix6) {
beginShape(QUADS);
texture(pix);

// +Z "front" face
vertex(-1, -1, 1, 0, 0);
vertex( 1, -1, 1, 1, 0);
vertex( 1, 1, 1, 1, 1);
vertex(-1, 1, 1, 0, 1);
endShape();
beginShape(QUADS);
texture(pix2);
// -Z "back" face
vertex( 1, -1, -1, 0, 0);
vertex(-1, -1, -1, 1, 0);
vertex(-1, 1, -1, 1, 1);
vertex( 1, 1, -1, 0, 1);
endShape();
beginShape(QUADS);
texture(pix3);
// +Y "bottom" face
vertex(-1, 1, 1, 0, 0);
vertex( 1, 1, 1, 1, 0);
vertex( 1, 1, -1, 1, 1);
vertex(-1, 1, -1, 0, 1);
endShape();
beginShape(QUADS);
texture(pix4);
// -Y "top" face
vertex(-1, -1, -1, 0, 0);
vertex( 1, -1, -1, 1, 0);
vertex( 1, -1, 1, 1, 1);
vertex(-1, -1, 1, 0, 1);
endShape();
beginShape(QUADS);
texture(pix5);
// +X "right" face
vertex( 1, -1, 1, 0, 0);
vertex( 1, -1, -1, 1, 0);
vertex( 1, 1, -1, 1, 1);
vertex( 1, 1, 1, 0, 1);
endShape();
beginShape(QUADS);
texture(pix6);
// -X "left" face
vertex(-1, -1, -1, 0, 0);
vertex(-1, -1, 1, 1, 0);
vertex(-1, 1, 1, 1, 1);
vertex(-1, 1, -1, 0, 1);

endShape();
}

void mouseDragged() {
float rate = 0.01;
rotx += (pmouseY-mouseY) * rate;
roty += (mouseX-pmouseX) * rate;
}

This is the errors i am getting:
You must first call texture() before using u and v coordinates with vertex()

You need to actually have those pictures in the data folder of your sketch!

lol yup thats the problem i dont get why i am getting this error when the pictures are in the DATA file

EDIT: i just realized that i saved in the wrong project file and now my new problem is how can i put a little text right above the cube
i dont get how the refrence page explains it

Use arrays!

// to initialize

int number_of_images = 6;

PImage[] pix = new PImage[num_of_images];

for (int i = 0; i < num_of_images; i++) {

pix[i] = loadImage("pix"+i+".jpg");

}
