Déplacement d'Obj en WebGL

Version imprimable

Bonjour à tous, je souhaite pouvoir limiter le déplacement de l'OBJ seulement si on se trouve sur la zone d'affichage mais après plusieurs tentatives avec des mouseover mouseout toujours aucun résultat. Voici le code que j'utilise :

En espérant avoir été clair :?

C'est bon j'ai réussi à détecter quand je suis dans la zone et tout marche comme je le souhaite du moins presque ... parce que lorsque je colle la zone d'affichage en haut à droite l'objet ne suis plus vraiment la souris, il tourne en rond :weird: je vois pas trop pourquoi :) .

Salut, je pense que tu devrais développer ton problème ainsi que ce que tu souhaites obtenir, car ce n’est pas clair et ton code l’est encore moins.
Pour nous aider à comprendre tu devrais mettre en ligne une demo (sur JSFiddle par exemple)

Le code que tu poste me semble bien compliqué, pourquoi utilise tu des coordonnées sphériques ? si je me réfère au nom du constructeur FirstPersonControls, je peux qu’en déduire que tu souhaites déplacer la camera comme dans un jeu de FPS, mais quel rapport avec le déplacement d’un model OBJ ?
