Untuk memahami intipati transformasi dengan lebih baik, kami memutuskan untuk melengkapkan model kiub tiga dimensi, yang boleh mencapai kesan putaran tiga dimensi 360 darjah tanpa jalan buntu.
Namun, sukar untuk menentukan susunan pandangan setiap muka apabila berputar, dan ia masih belum diselesaikan dengan sempurna. Saya harap seseorang dapat menjawabnya!
