[solved] Drawing a cube

Is there something wrong with this code? It doesn’t seem to draw all the faces of the cube.

#include <GL/freeglut.h>

float angle;

void display()
{
    glClear(GL_DEPTH_BUFFER_BIT | GL_COLOR_BUFFER_BIT);
    glLoadIdentity();
    glRotatef(angle, 0.5, 0.5, 0.0f);
    glBegin(GL_QUADS);

    // FACE ONE!!
    glColor4f(1.0f, 0.0f, 0.0f, 1.0f);
    glVertex3f(0.5, 0.5, 0.0);
    glVertex3f(0.0, 0.5, 0.0);
    glVertex3f(0.0, 0.5, 0.5);
    glVertex3f(0.5, 0.5, 0.5);    

    // FACE TWO!!
    glColor4f(0.0f, 1.0f, 0.0f, 1.0f);
    glVertex3f(0.5, 0.5, 0.0);
    glVertex3f(0.5, 0.5, 0.5);
    glVertex3f(0.5, 0.0, 0.5);
    glVertex3f(0.5, 0.0, 0.0);

    // FACE THREE!!
    glColor4f(0.0f, 0.0f, 0.0f, 1.0f);
    glVertex3f(0.5, 0.5, 0.5);
    glVertex3f(0.0, 0.5, 0.5);
    glVertex3f(0.0, 0.0, 0.5);
    glVertex3f(0.5, 0.0, 0.5);

    // FACE FOUR!!
    glColor4f(0.0f, 0.0f, 1.0f, 1.0f);
    glVertex3f(0.5, 0.5, 0.0);
    glVertex3f(0.0, 0.5, 0.0);
    glVertex3f(0.0, 0.0, 0.0);
    glVertex3f(0.5, 0.0, 0.0);

    // FACE FIVE!!
    glColor4f(1.0f, 1.0f, 0.0f, 1.0f);
    glVertex3f(0.5, 0.5, 0.0);
    glVertex3f(0.5, 0.5, 0.5);
    glVertex3f(0.5, 0.0, 0.5);
    glVertex3f(0.5, 0.0, 0.0);

    // FACE SIX!!
    glColor4f(0.0f, 1.0f, 1.0f, 1.0f);
    glVertex3f(0.5, 0.0, 0.0);
    glVertex3f(0.0, 0.0, 0.0);
    glVertex3f(0.0, 0.0, 0.5);
    glVertex3f(0.5, 0.0, 0.5);

    glEnd();
    
    glutSwapBuffers();
}

void rotation(int timer)
{
    angle += 0.5f;
    glutTimerFunc(1000 / 50, rotation, timer);
}

void framerate(int timer)
{
    glutPostRedisplay();
    glutTimerFunc(1000 / 100, framerate, timer);
}

int main(int argc, char** argv)
{
    glutInit(&argc, argv);
    glutInitDisplayMode(GLUT_DEPTH | GLUT_RGBA | GLUT_DOUBLE);
    glutInitWindowPosition(0, 0);
    glutInitWindowSize(600, 600);
    glutCreateWindow("dimension3");
    glEnable(GL_BLEND);
    glutDisplayFunc(display);
    glClearColor(1.0f, 1.0f, 1.0f, 1.0f);
    glutTimerFunc(1000 / 100, framerate, 1);
    glutTimerFunc(1000 / 50, rotation, 2);
    glutMainLoop();
    return 0;
}

I’ve enabled depth test and that seems to have sorted most of the faces except one. The remaining one is no doubt an error on my part.

Hi two things,

1. You are repeating the coordinates of face two in face five
   change the coordinates of face 5 to this

 // FACE FIVE!!
    glColor4f(1.0f, 1.0f, 0.0f, 1.0f);
    glVertex3f(0., 0.5, 0.0);
    glVertex3f(0., 0.5, 0.5);
    glVertex3f(0., 0.0, 0.5);
    glVertex3f(0., 0.0, 0.0);

2)Enable depth test
glEnable(GL_DEPTH_TEST); after u enable blending in main.

See if this hlps.
