Membuat Rumah Sederhana dengan OpenGL

Minggu, Januari 08, 2012 | 0 Comments

Sekarang, saya ingin mencoba membuat sebuah rumah sederhana dengan satu pintu, empat jendela dan pagar yang mengelilingi rumah. Untuk membuat rumah ini, kita hanya menggabung-gabungkan bentuk-bentuk yang sudah di sediakan oleh glut. Proyek ini juga menggunakan transformasi yaitu translasi, skala dan rotasi.

Berikut screenshot rumah yang sudah saya buat



Interaksi keyboard yang digunakan yaitu:
tombol d = untuk menjauhkan dan mendekatkan objek
tombol x = untuk merotasi objek terhadap sumbu x
tombol y = untuk merotasi objek terhadap sumbu y
tombol z = untuk merotasi objek terhadap sumbu z

Berikut kode program selengkapnya

#include "stdlib.h"
#include "gl/glut.h"

int w=600, h=600, z=0;
int x1=0, y1=0, sudut=0, z1=0;
float skalaX=1, skalaY=1, skalaZ=1;
int cx, cy;

void myKeyboard(unsigned char key, int x, int y){
 if (key =='a') z+=5;
 else if (key == 'd') z-=5;
 else if (key == 'q') skalaX+=0.5;
 else if (key == 'w') skalaX-=0.5;
 else if (key == 'e') skalaY+=0.5;
 else if (key == 'r') skalaY-=0.5;
 else if (key == 't') skalaZ+=0.5;
 else if (key == 'u') skalaZ-=0.5;
 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;
 }
}
