J'essaye de rendre un carré avec une texture. Est-ce que quelqu'un sait pourquoi cette texture semble être déplacée ou désalignée?C++: La texture DirectX est mal alignée/décalée

Pouvez-vous s'il vous plaît nous montrer les tampons vertex/index? Merci! – Rakete1111
Ok, j'ai mis à jour le code source dans le message. – 436c75656c657373Programmer
Vous pouvez essayer d'utiliser l'adressage de texture de pince pour déterminer s'il s'agit d'un problème uv ou d'un problème de mise à jour de texture. En outre, le dernier paramètre de 'UpdateSubresource' devrait être 0, pas la largeur, car il s'agit d'un pitch de profondeur, et vous n'en avez pas ici. – galop1n
