Keterangan :

Untuk masalah gambar, gunakan gambar dengan format BMP. Letakkan gambar di folder yang sama dengan letak penyimpanan file codeblock tersebut.

Perhatikan juga hal ini :

Untuk melihat dari berbagai sudut kamar, ganti gluLookAt, berikut script-nya :

gluLookAt(1.0, 0.8,  3.3,    1.0, 0.8,  1.0,    0, 1, 0);

gluLookAt(0.7, 5.2,  1.2,    0.7, 0.0,  1.2,    0, 0, 1);

gluLookAt(0.0, 0.95,  3.0,    1.5, 0.95,  1.0,    0, 1, 0);

gluLookAt(0.0, 0.95,  2.8,    1.0, 0.95,  1.0,    0, 1, 0);

Pilih salah satu saja.

Sekian.
