لا يستطيع هذا الجهاز أو المتصفح رسم الأبعاد الثلاثة (WebGL غير متاح)، لذلك يستخدم الدرس الرسم ثنائي الأبعاد. لا شيء ناقص: الخطوات والزوايا والإجابات هي نفسها.
ركّز على المشهد، ثم: سهما اليسار واليمين يديران العرض. سهما الأعلى والأسفل يميلانه. الزائد والناقص للتكبير والتصغير. الصفر يعيد الضبط. مفاتيح الأرقام تختار زاوية الرؤية. D يبدّل بين النموذج ثلاثي الأبعاد والرسم ثنائي الأبعاد. على شاشة اللمس، اسحب جانبيًا لتدوير العرض؛ والسحب للأعلى أو الأسفل يمرّر الصفحة كالمعتاد. ولكل إجراء زر أيضًا.
