Cara membuat objek Sphere menggunakan OpenGL

Halo semuanya...Terima kasih sudah datang di blog saya. Disini saya akan membagikan source code menggunakan OpenGL seperti gambar dibawah ini.

Source Code

#include <stdlib.h>

#include <glut.h>

int w=400, h=400, z=0;

int x1=0, y1=0, sudut=0, z1=0, skalaX=0, skalaY=0;

void renderScene(void){

    glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);

    //glClearColor(1,1,1,1);

    glLoadIdentity();

    glTranslatef(0,0,z);

    glRotatef(sudut,x1,y1,z1);

    glPushMatrix();

    glTranslatef(0,-4,0);

    glColor3f(1,0,1);

    glutWireSphere(6,16,16);

    glPopMatrix();

    glPushMatrix();

    glTranslatef(0,0,0);

    glColor3f(0,1,0);

    glutWireSphere(3,15,15);

    glPopMatrix();

    glPushMatrix();

    glTranslatef(0,4,0);

    glColor3f(0,0,1);

    glutWireSphere(6,16,16);

    glPopMatrix();

    glutSwapBuffers();

}

void resize(int w1,int h1){

    glViewport(0,0,w1,h1);

    glMatrixMode(GL_PROJECTION);

    glLoadIdentity();

    gluPerspective(45.0,(float) w1/(float) h1, 1.0,300.0);

    glMatrixMode(GL_MODELVIEW);

    glLoadIdentity();

}

void myKeyboard(unsigned char key, int x, int y){

    if (key =='a') z+=5;

    else if (key == 'd') z-=5;

    else if (key == 'x') {

           x1=1;

           y1=0;

           z1=0;

           sudut+=10;

    }

    else if (key == 'y') {

           y1=1;

           x1=0;

           z1=0;

           sudut+=-10;

    }

    else if (key == 'z') {

           y1=0;

           x1=0;

           z1=1;

           sudut+=-10;

   }

}

void mySpecialKeyboard(int key, int x, int y){

   switch(key){

         case GLUT_KEY_UP:

         z+=5;

         break;

         case GLUT_KEY_DOWN:

         z-=5;

         break;

   }

}

void init(){

    glClearColor(0,0,0,1);

    glEnable(GL_DEPTH_TEST);

    glMatrixMode(GL_PROJECTION);

    glLoadIdentity();

    gluPerspective(45.0,(GLdouble) w/(GLdouble) h, 1.0,300.0);

    glMatrixMode(GL_MODELVIEW);

}

void timer(int value){

    glutPostRedisplay();

    glutTimerFunc(50,timer,0);

}

void main (int argc, char **argv){

    glutInit(&argc, argv);

    glutInitDisplayMode(GLUT_DOUBLE | GLUT_DEPTH | GLUT_RGBA);

    glutInitWindowPosition(100,100);

    glutInitWindowSize(w,h);

    glutCreateWindow("3D");

    gluOrtho2D(-w/2,w/2,-h/2,h/2);

    glutDisplayFunc(renderScene);

    glutReshapeFunc(resize);

    glutKeyboardFunc(myKeyboard);

    glutSpecialFunc(mySpecialKeyboard);

    glutTimerFunc(1,timer,0);

    init();

    glutMainLoop();

}

Oke itu tadi source code menggunakan opengl. Segini dulu blog dari saya. Terima kasih udah mampir....
