Intro : <\/strong><\/p>\n

Il est n\u00e9cessaire de manipuler une bonne dizaine<\/strong> d’objets ou d’interfaces pour initialiser DirectX 11 avant de commencer tout affichage 3D.<\/p>\n

Pr\u00e9requis : <\/strong><\/p>\n

– Avoir d\u00e9j\u00e0 lu le code pour initialiser DirectX 10 ou 11<\/em><\/p>\n
