Kubus 3 Dimensi di DevC++

Membuat Kubus 3D dan menempelkan objek foto pada bidang kubus tersebut.

Pertama, kita harus menggunakan imageLoader.cpp dan imageLoad.h.
Kemudian dalam file main.cpp kita akan membuat coding bagaimana kita membuat kubus dan  menempelkan objek foto pada setiap sisinya tersebut.
Coding nya seperti ini :

#include <iostream>
#include <stdlib.h>
#ifdef __APPLE__
#include <OpenGL/OpenGL.h>
#include <GLUT/glut.h>
#else
#include <GL/glut.h>
#endif
#include “imageloader.h”

const float BOX_SIZE = 7.0f;
float _angle = 0; //Rotasi terhadap box
GLuint _textureId;
void handleKeypress(unsigned char key, int x, int y) {
switch (key) {
case 27:
exit(0);
}
}
//Membuat gambar menjadi tekstur
GLuint loadTexture(Image* image) {
GLuint textureId;
glGenTextures(1, &textureId);
glBindTexture(GL_TEXTURE_2D, textureId);
glTexImage2D(GL_TEXTURE_2D, 0, GL_RGB, image->width, image->height, 0, GL_RGB, GL_UNSIGNED_BYTE, image->pixels);
return textureId;
