Shader glsl : Problème pour passer une texture en paramètre dans le shader

Bonjour, voulant développer un shader de bump mapping j'ai commencé par recuperer celui present sur codessources et l'ai modifié pour l'appliquer dans une application opengl, mais le shader n'agit pas sur les textures. J'ai tout vérifié mais je n'arrive pas à trouver! Pouvez-vous m'aider ?
