Ada yang mau bikin kayak gini gaaaaaaaaak????? :D Yuk merapat! kita main-main sama Grafika Komputer.
Kita buat program yang menampilkan
sebuah rumah dengan atap yang berbeda warna dengan temboknya dan dikelilingi
oleh pagar.
Nih Syntaxnya:
#include
#include
#include
int millis=1;
int action=0;
int w = 640, h = 640;//variabel global
float x=0,y=0,z=-25, teta=0, masuk=0;//posisi awal koordinat
void atap(void){
glPushMatrix();
glEnable(GL_COLOR_MATERIAL);
glTranslatef(0,0.5,-4);
glRotatef(teta,0.,1.,0.);
glColor3f(0,0,1);
glRotatef(90,-1.,0.,0.);
glutSolidCone(1.2,1.,20.,20);
glDisable(GL_COLOR_MATERIAL);
glPopMatrix();
}
void pintu(float alpa, float x, float y,float z, float r, float g, float b){
glPushMatrix();
glTranslatef(x,y,z);
glRotatef(alpa,0,1,0);
glColor3f(1,0,1);
glScalef(0.6,1.,0.01);

glPopMatrix();
}

}
