Contoh Program C++ || Membuat Gambar 2D With C++

Assalamualaikum hamba Allah...........
Pada postingan kali ini saya akan membagikan srouce C++ lagi dan lagi.
Postingan kali ini saya akan membuat meja dan kursi 2D (burik sih).
Langsung saja saya share sroucenya dibawah ini:

//program dua dimensi

#include<GL/glut.h>

#include<math.h>

typedef struct {

            float x,y;

} point2D_t;

typedef struct {

            int r,g,b;

} color_t;

void setColor ( color_t col )

{ glColor3f(col.r, col.g, col.b); }

void fillPolygon (point2D_t pnt[], int n, color_t color)

{

            int i;

            setColor(color);

            glBegin(GL_POLYGON);

            for (i=0; i<n; ++i)

            {

                        glVertex2f(pnt[i].x, pnt[i].y);

            }

            glEnd();

}

void drawPolygon(point2D_t pnt[], int n)

{

            int i;

            glBegin(GL_POLYGON);

                for(i=0; i<n; i++)

                        glVertex2f(pnt[i].x, pnt[i].y);

            glEnd();

}

void userdraw()

{  static int tic = 0;

   point2D_t

                        meja[4]={{20,80},{60,160},{200,160},{160,80}};

   color_t magenta ={1,0,1};

       fillPolygon(meja,4, magenta);

               //setColor(1,0,1);

               drawPolygon(meja,4);

   point2D_t

               depankiri[4]={{20,20}, {20,80}, {30,80}, {30,20}};

   color_t white ={1,1,1};

       fillPolygon(depankiri,4, white);

               //setColor(1,1,1);

               drawPolygon(depankiri,4);

   point2D_t

               depankanan[4]={{150,20},{150,80},{160,80},{160,20}};

   color_t green ={0,1,0};

       fillPolygon(depankanan,4, green);

               drawPolygon(depankanan,4);

               point2D_t

               belakangkiri[4]={{60,50},{60,80},{70,80},{70,50}};

   color_t yellow ={1,1,0};

       fillPolygon(belakangkiri,4, yellow);

               drawPolygon(belakangkiri,4);

               point2D_t

               belakangkanan[4]={{190,50},{190,140},{200,160},{200,50}};

   color_t red ={1,0,0};

       fillPolygon(belakangkanan,4, red);

               drawPolygon(belakangkanan,4);

               point2D_t

                        kursi[4]={{220,80},{240,120},{320,120},{300,80}};

   color_t birumuda ={0,1,1};

       fillPolygon(kursi,4, birumuda);

               //setColor(0,0,1);

               drawPolygon(kursi,4);

   point2D_t

               depankiri1[4]={{220,20}, {220,80}, {230,80}, {230,20}};

   color_t hijau ={0,1,0};

       fillPolygon(depankiri1,4, hijau);

               //setColor(0,1,0);

               drawPolygon(depankiri1,4);

   point2D_t

               depankanan1[4]={{290,20},{290,80},{300,80},{300,20}};

   color_t biru ={0,0,1};

       fillPolygon(depankanan1,4, biru);

               drawPolygon(depankanan1,4);

             point2D_t

               belakangkiri1[4]={{240,50},{240,80},{250,80},{250,50}};

   color_t kuning ={1,1,0};

       fillPolygon(belakangkiri1,4, kuning);

               drawPolygon(belakangkiri1,4);

               point2D_t

               belakangkanan1[4]={{310,50},{310,100},{320,120},{320,50}};

   color_t merah ={1,0,0};

       fillPolygon(belakangkanan1,4, merah);

               drawPolygon(belakangkanan1,4);

point2D_t

                        kursi1[4]={{300,80},{300,160},{320,200},{320,120}};

   color_t putih ={1,1,1};

       fillPolygon(kursi1,4, putih);

               //setColor(1,1,1);

               drawPolygon(kursi1,4);

              

               point2D_t

                        kursi2[4]={{290,160},{310,200},{320,200},{300,160}};

   color_t ungu ={1,0,1};

       fillPolygon(kursi2,4, ungu);

               //setColor(1,0,1);

               drawPolygon(kursi2,4);

                point2D_t

                        kursi3[4]={{290,160},{290,80},{300,80},{300,160}};

   color_t hijau1 ={0,1,0};

       fillPolygon(kursi3,4, hijau1);

               //setColor(0,1,0);

               drawPolygon(kursi3,4);

           

}

void display(void)

{          //clear screen

            glClear(GL_COLOR_BUFFER_BIT);

            userdraw();

            glutSwapBuffers();             }

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

glutInit(&argc,argv);//Inisialisasi Toolkit

glutInitDisplayMode(GLUT_DOUBLE|GLUT_RGB);

glutInitWindowPosition(100,100);

glutInitWindowSize(640,480);

glutCreateWindow("Gambar rumah");

glClearColor(0.0,0.0,0.0,0.0);

gluOrtho2D(0.,640.,-240.,240.);

glutIdleFunc(display);

glutDisplayFunc(display);

glutMainLoop();

return 0;

}
