Membuat Rumah 3D Dengan OpenGL

Juan Matheus    8/05/2020    OpenGL   

Membuat Rumah 3D dengan OpenGL sama seperti postingan saya yang sebelumnya kita membuat rumah 2D menggunakan OpenGL bedanya ya 3D dan 2D. Kita sudah belajar tentang yang 2D oleh karena itu kita akan meningkatkan skil kita lagi teman-teman, dengan membuat rumah 3D. Bedanya dimana sih ?

Langsung saja siapkan tools yang kalian gunakan kemudian copy script dibawah ini : 

#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;
 }
}

Jika kita jalankan script di atas makan hasilnya akan seperti gambar dibawah ini :
